Video Transcript for Review of Derale Thermostatic Sandwich Adapter For GM Application - D25720

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a brief look at this Derale thermostatic sandwich adapter for GM applications. This high-quality, die-cast aluminum, thermostatic sandwich adapter with the half-inch NPT ports is going to provide external lines for simple installation of an oil cooler without having to reposition your oil filter, allowing oil cooler than 180 degrees to bypass your heat exchanger. So, it's going to ensure a quicker engine warm-up. Now, this is going to install between your stock engine oil filter landing and the oil filter so your stock filter is retained.

And the engine filter thread size is 13/16 of an inch by 16. This also includes a 13/16 of an inch by 16 sleeve nut that you can see right here. And then as you can see here, this also includes an O-ring and the O-ring diameter is 3 1/2 inches. And the overall thickness of this sandwich adapter itself, sitting right at 2 1/4 inches thick. Well, that's gonna conclude our brief look today.

I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

  • Engine Oil Cooler Sandwich Adapter for a 2003 Chevy Suburban 1500 with a 5.3 Liter Engine
    According to Derale, the 5.3 liter engine used in 2007 and 2008 uses a filter thread size of 22 x 1.5mm and an O-ring size of 2-3/4 inches. You would need # D25734. However, to be on the safe side, I recommend Derale Thermostatic Sandwich Adapter, # D25782. It will work with engine thread filter sizes 3/4 inch-16, 13/16 inch-16, 18 mm x 1.5 mm, 20 mm x 1.5 mm, and 22 mm x 1.5 mm. And fits O-ring sizes 2-3/4 inches or 3-1/2 inches. So it basically covers anything that could be on your Suburban.

  • Availability of a Derale Low-Profile Sandwich Adapter for a 2006 Chevrolet Duramax Deisel
    The correct Sandwich Adapter for your 2006 Chevy Duramax is the Derale Thermostatic Sandwich Adapter - 13/16-16 Engine Filter Threads, item # D25720. There is not a Low profile adapter available at this time for the 3-1/2 inch O-ring filter size. You will need to measure the area you have below your existing filter for installation and removal of the oil filter after installing the adapter. The # D25720 adapter is 2-1/4 inches thick so you will need at least 2-1/4 inches plus the thread...

  • Availability of Non-Thermostat Controlled Oil Filter Sandwich Adapter
    We have non-thermostatic controller sandwich adapters for oil coolers that it sounds like would be your best option. For that you would want the part # D15735. It comes with multiple thread sizes as well to allow you to fit it to nearly all vehicles with spin on oil filters.

  • Derale Thermostatic Sandwich Adapter Recommendation for a 2007 GMC 3500HD Dually
    I would recommend you get a Derale Thermostatic Sandwich Adapter # D25782 as it comes with multiple adapter sizes to ensure that you get the correct size for your application. I did some checking and it looks like you will need the 22 mm x 1.5 mm size for your 2007 GMC 3500HD. This is one of the included sizes in the # D25782. However, since you said you have a LBZ engine and I was under the impression that the 2007 trucks had the LMM engine the # D25720 would be a safe recommendation...

    It seems like you're wanting to cool your engine or transmission down. If it's the engine you're wanting to cool, you can grab this kit # D15605 which comes with a sandwich adapter with multiple thread sizes to ensure that it will thread into your Tacoma. If you're wanting to add an oil cooler to your 2010 Toyota Tacoma, you won't need the Derale Thermostatic Sandwich Adapter # D25720. All you need is a cooler like this one # D12906.

  • Which Engine Oil Cooler Kit will Work on a Chevy 350 Crate Motor In a 1934 Ford
    If your filter is the larger style GM filter you will need to use the Derale Tube-Fin Engine Oil Cooler Kit w/ Sandwich Adapter (Multiple Threads) - Class III, item # D15505, which includes the adapter for the larger filter. If you are not sure which filter you have the # D15505 will work on the engine without the use of the adapter. If you have the smaller filter on your vehicle you can use the Derale Tube-Fin Engine Oil Cooler Kit w/ Sandwich Adapter (Multiple Threads) - Class III,...

  • Thread Sizes of the Derale Thermostatic Sandwich Adapter # D25720
    The Derale Thermostatic Sandwich Adapter # D25720 has 1/2" NPT ports and is compatible with an engine filter thread size of 13/16"-16. I wish I could tell you up front if it would fit on your application but you will just need to do some checking on your equipment and compare it with these specs. This is especially the case if you are building a custom piece for your Duramax. If you have factory threads then it should fit as your factory threads should be 13/16"-16. The installation instructions...
