MB Sturgis Propane Fittings - 100473-12

  • Hoses
  • Pigtail Hoses
  • 1 Foot Long
  • 1/4 Inch - Male NPT
  • Type 1 - Female
  • MB Sturgis

Pigtail makes the connection from the propane tanks on your trailer to the propane regulator. Also used to connect tanks to a high-pressure regulator to carry gas to a 2-stage regulator. Check valve prevents hazardous backflow leakage.


Features:

  • Propane pigtail connects your propane cylinder to a regulator
    • Used for single or dual tank setups on the front of your travel trailer
    • Also used to connect a remote tank to a high-pressure regulator
  • Female Type 1 fitting connects to the valve on your propane cylinder
  • Male NPT connects to a propane regulator
  • Built-in bypass mode shuts gas off when flow reaches maximum capacity for safety
    • Thermal shut-off device turns off gas flow in extreme heat caused by open flame
    • Excess-flow safety device limits gas flow in the event of a severe leak
  • Durable thermoplastic hose and brass fittings approved for LP gas only
    • Rated for high pressure and high flow rate to handle unregulated propane
    • UL569 and ANSI Z21-81 certified
  • Made in the USA


Specs:

  • Temperature range: -40 F to 140 F
  • Hose dimensions: 12" long x 1/4" inner diameter
  • Hose fittings:
    • Female Type 1
    • 1/4" Male NPT
  • Maximum pressure rating: 350 psi
  • Maximum flow capacity: 450,000 Btu per hour
  • 1-Year limited warranty


This propane hose is ideal for travel trailers with a split-tank system. This kind of system features 1 cylinder on the driver's side and 1 cylinder on the passenger's side of your trailer. This hose connects the cylinder on the passenger's side to a high-pressure regulator. An additional hose (sold separately) will then carry the propane from the high-pressure regulator to the 2-stage regulator on the driver's side of your trailer.


Bypass Mode for Safety

This Type 1 connector will go into bypass mode if the flow rate surpasses the maximum flow capacity for this connector, which is 450,000 Btu per hour. A ball inside of the fitting will push an internal spring down, pressing firmly against the bottom of the fitting to shut off the flow of gas.


When choosing a Type 1 connector, consider your overall propane demands and choose a connector with a flow rate that just exceeds it. That way, you won't trigger the bypass mode during normal use, but it will trigger in the event of a leak. If the bypass valve engages, stop using gas and start checking your connections for leaks.

I THOUGHT I WOULD NEVER BE ABLE TO FIND AN AMERICAN PART MADE WITH HIGH QUALITY TRUE RUBBER HOSE AND QUALITY CLAMPS WITH A PERFECT TANK FITTING. ETRAILER OBTAINED THIS FOR ME(AFTER A LITTLE WAIT) AND I WAS SO HAPPY TO RECEIVE IT. THANK YOU FOR THE QUALITY EQUIPMENT, I HAVE COME TO EXPECT FROM YOUR COMPANY.



by:

This is what you want. Don't buy the cheap chinese crap. I did to replace original USA made pigtails (15 years old) and after losing a couple of tanks of propane, figured out they were slowly leaking. Cheap pigtails were only a couple of years old too. Don't let the fancy stainless steel braiding fool you like it did me.



by:

Both Propane pigtails fit perfectly with no leaks



by:

I replaced these in 2023 on my 2015 travel trailer as the originals had dry rotted and failed. The rubber is still pliable and these are working like they should.



by:

First one leaked jyst behind the type-1 connector at the hose. I was promptly sent another that didn't leak. Quality customer service and a good product.



by:

Great service. Quick answers to my questions and part was ordered and received quickly and correctly. Thank you!



by:

This propane hose has already far outlived the original factory one, and recently survived a 14,000 mile cross country trip to Alaska and thru Canada on some extremely rough and dusty roads.



by:

I purchased these to update my Lp supply system because mine were hardened and fairly old. They looked really good and fit perfect. We replaced the hoses and went on about testing them and found them to be leaking at both ends. The coupler and the brass fitting was fine, it was the hose connections at the crimp. Not just one of them but both were leaking, and surprisingly both hoses. We were using our camper at the time so I had to put the old ones back on. I got sick and never sent them back. This is only the second time out of all the parts I've purchased from etrailer that had failed, so I wasn't overly upset about. Good looking hoses, just bad crimps. Thankfully I bubble checked them and didn't just put them on and walk off. If I would have sent them back I'm sure etrailer would have replaced them, I just never did. I will still continue to buy my parts from etrailer, stuff happens no fault of them.



by:

A item that I feel should be replaced on a routine basis



by:

I installed on a travel trailer. It hasn't been used yet on a camping trip but it was easy to install. I did a soapy water check on it and it didn't leak.



by:

My previous hose is 1'. When I ordered this one it was 2 inches shorter. I'll be needing to return it. Not sure if I missed that but it might be something to consider calling out somewhere.



by:

The website was easy to use and find the correct parts.



by:

Last week this propane hose started leaking.
So I'm going to buy a new one .
I was hoping it would of lasted longer than this.

Wait! Dont purchase a new one yet, I see this has a 1 year warranty! Let me get you to our customer service department.

Everything worked great. Fixed my propane line leak (regulator leaked)

The hose we ordered fit perfectly and arrived in a timely manner. It's easy to order parts from etrailer.com

I received them very quickly.well made good fit no leaks



by:

Arrived as described. Attached photo shows set up prior to mounting regulator.



by:

Made in USA! Thank you! I tried to by local, still waiting for a call back 2 1/2 weeks later...etrailer will be my first stop for my next RV need!



by:

Hello,

Thank you for a no worries
order, my delivery was on time and all it’s good..



by:

Order was received on time as stated. Items were stocked.

I used these as replacements for two older style hoses on my RV tanks. The old ones required the use of a wrench to remove them from the tank. It was an easy conversion that took less than 15 minutes.
On the connection to the regulator, I used yellow teflon gas tape on the threads as a precautionary measure. Still don't know if that was necessary, but didn't want to take a chance they might leak. So far, so good, no leaks at the connections.
They are reasonably priced good quality hoses. With the older hoses it was a pain to switch out empty tank for a full one. Eventually it got so difficult to get the hose thread started in the propane tank that I stripped one of them out, which is why I ordered new hoses from etrailer.
Tank swap outs are now a breeze, and no tools required! Wished I had done this years ago.
Standard shipment from etrailer was adequate and reasonably priced.

Still working good. Small purchase that has made life easier.



by:

Didn't last a year just bought another brand from etrailer couple months ago. Started leaking from the hose connection



by:

High quality made in USA propane pigtails. Note that these are 1/4 inch pipe thread ends for the older auto switching regulator on my 2007 Airstream International. The more common 1/8 inch reverse flare fitting will not fit mine. The 1/4 inch pipe thread pigtails are a little harder to find, and are able to flow more propane. I have a propane powered generator that thes work very well with.

Still solid, no leaks! Well made product.

Works as should fast delivery



by:

Order two of these to replace failed units on our trailer. Shopped on Amazon and saw tons of comments about people getting units that failed and leaked out of the box. Both of these look like high quality hose crimps and two weekends of use without any issues. Shipping was super quick and good communication. Would order from etrailer again.

Bought two of these to replace the originals that came from the factory. One year in and no problems. Seems higher quality then the originals.

  • Gas Log Set Needs Automatic Changeover 2-Stage Propane Regulator for Dual Propane Tanks
    The pressure regulators we have available are all a nominal 11" WC which is most common for RV appliances. Please verify your gas log set requires 12" WC minimum. If an 11" WC will work, I suggest the MB Sturgis Vertical 2-Stage Propane Regulator, # 108220. You will also need two Type 1 connection hoses to go from the tanks to the regulator, # 100473-12 is a 12 inch hose. This has a flow capacity of up to 400,000 Btu per hour.

  • Should Propane Leak From The Hose When I Remove The Tank on Fifth Wheel Trailer
    You are correct, gas should not be able to leak from the hose when you remove the tank. It sounds like you have a stuck or defective check valve in the regulator or the pigtail. Sometimes corrosion can build up and cause the back check valve to stay open. Some customers have been able to use a small amount of spray lubricant or PB Blaster to loosen up any build up that may have caused the check valve to stay open, but your best option is to replace the regulator and the hose completely,...

  • 12 Propane Pigtail
    If you have a 1/4 Inch - Male NPT, I suggest the # 100473-12. If you have a 1/4 Inch - MIF, then I suggest # 100833-12. If you have brass fittings in the inlets on the regulator then you most likely have the inverted flare.

    You can hook the MB Sturgis High Capacity Two-Stage Auto Changeover Regulator # 888001-MBS up between your two 20lbs propane tanks but the # 100473-12 will not work as supply lines because you need a male inverted flare tip like the MB Sturgis Propane Pigtail - Type 1 x 1/4" Male Inverted Flare - 15" Item # 100575-15-MBS.

  • Dual Propane Regulator Replacement for Older Trailer
    It looks like what you have there are dual propane tanks, so a dual propane regulator will be needed. The age of the trailer doesn't matter so long as the fittings on the tanks are current. So what you need is the Compact Low Pressure 2-Stage Automatic Changeover RV LP Gas Regulator # 37207-31525. For hoses you can use the 12 inch MB Sturgis Propane Hose Assembly - RV Type 1 w/ Back Check x 1/4" MPT # 100473-12. To mount this regulator if needed, you can use the U-Post RV LP Gas Regulator...

  • Propane Regulator Replacement For A 1992 Coleman Elite Royal Pop Up Camper
    Depending on your current regulator, you will want either a single stage like the MB Sturgis Single Stage Propane # 108072 or a dual stage like the MB Sturgis Horizontal 2-Stage Propane Regulator # 108221 to replace your current popup camper setup. Replacing the pigtail hose with the MB Sturgis Propane Hose Assembly - RV Type 1 w/ Back Check x 1/4" MPT - 12" # 100473-12 could also update your Coleman Elite propane setup.

  • Recommended Replacement For A Horizontal Propane Regulator
    Based on the picture you provided you have a horizontal two-stage regulator. For replacement I recommend the MB Sturgis Horizontal 2-Stage Propane Regulator - 11" Water Column Outlet # 108221 that you were already looking at and some Jamar's White Stuff # 37207-30555 to seal up the threads of the regulator to prevent any leaks. You'll want to ensure that the vent is placed down so that water build up in the regulator can properly dissipate out. I also recommend using a pigtail hose like...

  • Recommended Adapter Fittings To Go From A 1/4" NPT Male Fitting To A 3/8" Female Flare Fitting
    From what you're saying you have a 3/8 Female Flare fitting on your regulator and need to connect to propane tank with a pigtail hose. While we don't currently carry an adapter hose to meet this need we do have some adapters that can help get you there. You'll need to hook the MB Sturgis Propane Adapter Fitting # MBS77FR into the 3/8" female flare fitting on the regulator. From there you'll use the MB Sturgis Propane Bulkhead w/ Nut and Lockwasher # MBS47FR to connect that fitting to...

  • Regulator Kit Recommendation for 2006 Fleetwood Niagara
    I looked up your 2006 Fleetwood Niagara and it looks like it uses two tank setup like what a lot of pop up campers use. So for a regulator designed for dual tanks with an automatic changeover we have the Camco Regulator part # CAM59005 which allows you to connect both of your tanks to a hose for your heater. If you need new pig tail assemblies between the tanks and the regulator we have the part # 100473-12 which is a standard 12 inch long pigtail. None of these have O-rings though.

  • Hoses and Regulators Needed to Add Dual Tank Propane Setup to Trailer
    I attached a picture that shows what the typical dual tank setup looks like with the accessories needed labeled. First thing you need is pig tails to go from the tanks to the regulator like the part # 100473-12. Then for a dual tank regulator with automatic changeover we have the part # 37207-30395 that each of the pigtails would connect to. Then for a 12 foot long extension hose that would plug into outlet of the regulator you'd want the part # 100040-144-MBS. From there you'd connect...

  • What Size Pigtail Fitting Fits MB Sturgis Regulator # 88801-MBS
    On the MB Sturgis regulator part # 888001-MBS the inlet side has a 1/4 inch female inverted flare fitting and the output side is 3/8 inch NPT. So the pigtail side would need to have a 1/4 inch male fitting like the MB Sturgis part # 100473-12 which is 12 inches long.

  • Length of MB Sturgis Propane Hose Assembly, # 100473-12
    The overall length from end to end of the MB Sturgis Propane Hose Assembly, # 100473-12, is slightly greater than 12". However, once the 1/4" MPT is threaded into the regulator and the RV Type 1, with back check valve, is connected to the propane supply, you will have a bout 12" of length between regulator and valve connection. Providing about the same as you have with current hose.

  • Recommended Replacement Hose From Propane Tank to Regulator on 5th Wheel
    The hose and fittings sizes are standardized for RV's. Therefore, what you have is going to be a type 1 to either a 1/4" NPT or 1/4" Male Inverter Flare. If you have the former I recommend part # 100473-12 or part # 37207-30715 if you have the latter. That said, I get why you're confused as these fittings don't actually mic out to 1/4", they will measure larger but that does not correlate to their nominal size which would be the same for measuring any sort of NPT fitting.

  • Propane Pigtail to Use with MB Sturgis Horizontal 2-Stage Propane Regulator 108221

I believe this is what you currently have but I think the end you're seeing looks like the MB Sturgis Propane Adapter Fitting # 204120-MBS and I think the white plastic piece is part of the back-check.
