  • 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...

  • 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...

  • 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...

  • 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.

  • 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.
