So it's never a bad idea to pick up a replacement small plug, and a large plug for your tow vehicle and your towed vehicle. This is what's going to ensure the longevity and smooth running of your SMI system. This is going to go over the end of your female and male end, so that you don't have to worry about getting any dirt or debris inside your air hose fitting when you're not using it. We'll put one on our vehicle end too, just to keep the dirt and debris out of that also.My personal opinion, if I had a system just like this, I would want to make sure all of my plugs are all plugged up before I go anywhere after my trip. So that means when I unhook my air hose that stretch from my towed vehicle to my tow vehicle, I'm going to pick up a couple of these extra plugs and put them over top of the fittings on my hose too, just to make sure everything in that hose stays nice and clean.Well guys, with all that being said, that's going to do it for our review and replacement of our large and small rubber caps.

This hitch is amazing!!! Be prepared though it is very heavy! I love how easy it is to adjust to different heights and ball sizes with the 2 common sizes provided. The scale on the back can be helpful to let you know if you have the proper trailer weight. The more you use it the more you will like it!
Exact replacement for original lost cap. Thanks
Works well, found the old one
I keep loosing it. Not really needed.
Great product—terrific price—arrived quickly— etrailer always exceeds my expectations
THEY SHOULD BE A LITTLE TIGHTER, THE WORST PART IS POSTAGE FOR THE PART. THE PRICING EVENTUALLY LEADS YOU TO NOT EVEN REPLACING IT WHEN IT COMES OFF
I am a returning customer and again find the product and service excellent. I am sure I will be back yet again. I would recommend etrailer to my friends. I could not find the caps for my AF1 supplemental braking system even at their site - yet, I did find them on etrailer!
Perfect part …just what I needed.
Great products great service
The part is exactly what I needed, but is very expensive.
As described
I have ordered from etrailer several times and have always been pleased. The item was exactly as expected, so I give it 5 stars, your shipping process, let me down and I give it 1 star. The item was listed as “in stock” and I needed it for a trip so my braking system would work. It took several days for it to be shipped, then standard shipping days. Sorry, just not what I have come to expect from etrailer.
Perfect replacement.
Just what we ordered and nice to have s pares
e trailer is so quick with shipping ord ers
Perfect replacement caps! If you're like me and put these things in your pocket when hooking and unhooking, eventually one will go missing. I now have spares for the next time!
Great service and fast shipping!

Perfect. Thanks!
Always a pleasure to work with the folks at e-trailer. Professional but friendly and excellent products l
I bought some spare large and small air fitting covers used on our SMI Air Force One supplemental braking system. These small plastic covers can split after some use--as have the ones in use on my system. Not much more to say. They keep the dirt out of the lines. I always like to have a few spares.
Etrailer always gives good service. I usually look to them first for RV related parts.
I bought a number of these dust caps for the quick connect fitting of our auxiliary brake system. Because the plastic caps bend when being put on or pulled off, the ends of the caps can split.
The replacement caps work fine and my current supply should be good for several more years.
I purchased these extra air fitting caps for my Air Force One supplemental braking system because only one of each came with the system, they are essential for keeping the air lines clean, and it woud be easy to lose or misplace them. I received exactly what I ordered, and the price and delivery time were good.
Didn’t fit my fitting, no use to me

You mentioned that it did not fit and I wanted to ask if you were using it on your Quick-Disconnect air valve on your Air Force One supplemental braking system? Do you know the model number of the braking system?

Hi Jenny, yes I’m using a quick disconnect that was on the coach when I bought it. I use a M&G braking system, similar to the AF1. The quick connect air hose fitting I use came with the M&G brake I had installed on my Jeep. The vinyl cap I purchased was to small to go over the female quick connect fitting on the back of the coach...

Perfect and fast shipping!
Great products and helpful associates
The large cap quick disconnect seems sturdy enough to weather all four seasons here in the east. It should last quite a long time.
It will protect the coach’s SMI Air Force One air port and the toad vehicle air nipple.
I am satisfied with its sturdiness and time will reveal whether it protects from moisture and debris.
