Defender (defender.com) usually carries the Perko cork gaskets.RAW WATER STRAINER GASKETS
I cant really identify the manufacturer of the bronze raw water engine intake and A/C strainers. I think they are Perko. I need new gaskets / O-Rings for the top cap where you pull out the mesh strainer. Looks like 3 inch for engine and 2 inch for A/C. Does anyone know the correct part numbers?
