Sandwich Adapter question?

Hey guys I got a minor setback if anyone lend some advice. I did a Oil cooler this weekend on my 750i. The sandwich adapter um running is from Jeg’s the normal universal one 25782 - Derale Aluminum Thermostatic Sandwich Adapter. The O-ring that came with the adapter was too thin to get a seal on the motor. So I used one from a oil filter and I’m still getting a small leak. I’m wondering if anyone has used this setup and what O ring did you used to get a good seal on your adapter.

Most of those universal adaptors fit all types of cars but not all types of bikes. I used this one. Its made for the Kawie. It has a thick O-ring. Maybe you can go to an auto parts store and get a fat one to fit yours...or just get one like this. I have had no problems with it.

You have to be carefull on which adapter you get. These bikes have such a small sealing surface that some of the adapters where machined in such a way that part of it would not seal to the block. If you go over to highlifter and search for oil cooler with the username mikewalker, he go's through and expalins the problems with some adapters and the right ones to use.

Well I thought it was there. I don't know what happened to it. I know though that some of the adapters had this one spot on them that would not seal because of how small the sealing surface was on the bike, it left a part of it out in the open.

lowes carries every size and thickness of o-ring you could ever want. i'd take a gander over there.
