These are a high quality stainless steel sandwich plate adapter fitting in 13/16-16-UNF which is used on most early model GM 4 & 6 cyl, as well as Buick, Cadillac, Oldsmobile and Pontiac V8’s. They are be used with our oil filter sandwich plates for installing oil temp and pressure sensors, but can also be used with other aftermarket oil cooler sandwich plates etc to replace possibly poor quality alloy fittings that may have been included with your plate. Before you order make sure to check which fitting type you need for your vehicle, make sure if ordering the 13/16" 16 UNF fitting it’s the right type for your car. If in doubt, feel free to give us a yell and we would be happy to assist.
The reason we have stocked these stainless steel fittings is because a lot of the sandwich plates on the market ship with cheap alloy fittings which to be brutally honest we wouldn’t personally trust on our vehicles, so we couldn’t sell something that we wouldn’t ourselves use.
These are high quality stainless steel fittings, strong and reliable, which is all you would want to use when this is a pretty critical component. As you can see we have kept the price on these very low, much lower than you will find elsewhere.
