RG-535823 OIL FILLER CAP GASKET

July 20, 2022

This Real silicone gasket for the oil filler cap on Continental engines fit perfectly (after I spent 30 minutes cleaning the old disintegrated cork gasket out of the oil filler cap) and appears that it will seal the cap and otherwise work well.

Like all the parts I order off aircraft Spruce they ship quickly and works. Anytime I’ve had technical questions they was very helpful.

Very nicely made. Clear PN markings on the gasket. Proper fit for a TCM IO-520-D on a C A185F oil filler tube cap.. I expect to get many years of trouble free, leak free service from this silicone robber gasket.

I ordered this part for my io550. It was not the right size, but too small.
