Title: engine oil cooler adapter seal
Post by: Jack4159 on November 27, 2022, 08:09:27 AM
I've looked at all the usual places but can't find a replacement seal, does anyone know if these are available anywhere?
If not any suggestions?
Thanks as always.

I am not familiar with a current off the shelf replacement. I am sure there is something similar already made out there that will work. You could get some sheet rubber that is fairly stiff and cut it out using the adapter as a pattern if you don't have the defective original. I am fortunate to have a rubber products supplier Hanna Rubber in KC where I live so I can more easily sort through possible alternatives. If you use something flexible like inner tube you will need to glue it to the adapter and letting it set up before clamping the oil cooler adapter to the Ford filter adapter.

My Boss 302 adapter used this gasket. A thin paper gasket and thin layer of sealant is fine. The stock gasket was thin aluminum with a thin layer of rubber on each side.

Jack I don't think your seal is factory. I seem to recall the filter seal is correct on the top side

I was just looking for the same thing and have a seal on the adapter the same as in your pic.

The Shelby adapter takes an o ring from a Fram oil filter. It sits in a machined groove in the adapter itself. The Ford service listing actually shows a Fram number for that o-ring. Just pull one off of a used oil filter. That's all the thing is.

I've never seen anything like the "gasket" posted in the OP's picture.



The "69-70 Boss 302 adapter " uses the rubber coated gasket pictured in Van's post. It won't work on the Shelby adapter.

It also shows an o-ring gasket fitting under the fluid bolt. Mine works without that.

The B2 adapter also fits the 351-c and 429 series of that era but can be backfit onto any 289 type block.

The Shelby part is unique to the FE's. The 427 Cobras have their own version.


The B2 adapter also has a "pressure releif spring" built in. What in fact that is, is a thermal switch to open circulation to the cooler/radiator at a certain temperature. I believe that is around 185°F. The Shelby version has no such device incorporated into it.

Just to clarify the street 427/428 Cobra's did not use any remote cooler adapter . Only the competition models or SC model used the remote oil cooler adapter.
