DJK Posted August 18, 2023 Report Share Posted August 18, 2023 Looking for a source for the rubber seal that goes into the groove of the cover on a Purolator by-pass filter assembly. It calls for a P40 filter which crosses to a Wix 51201, unfortunately, the seal is the wrong one. The dimensions are : OD = 4 5/8" ID = 4 1/8" thickness = .125". I have tried McMaster Carr etc. Quote Link to comment Share on other sites More sharing options...
Ivan_B Posted August 19, 2023 Report Share Posted August 19, 2023 I am still using the old one. Yours is also just a rubber gasket, isn't it? You can just cut it out from the regular gasket material of appropriate thickness. Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted August 19, 2023 Report Share Posted August 19, 2023 Since these older gasket are not easy to find I make my own gaskets for my by pass oil filter lid. All you need is a compass and pair of sissors and also make a couple gaskets. The mother of invention is the savior when something is necessary needed right now.

Sniper Posted August 19, 2023 Report Share Posted August 19, 2023 A little thicker than yours https://www.mcmaster.com/4061T323/ Quote Link to comment Share on other sites More sharing options...
vintage6t Posted August 20, 2023 Report Share Posted August 20, 2023 If you happen to have a Cricut Maker in the house then cut your own. Admittedly for the gasket you need it's complete overkill compared to what @desoto1939 suggested but way more fun. Quote Link to comment Share on other sites More sharing options...

I will attempt to make one if I can't come up with one. Thanks guys. Quote Link to comment Share on other sites More sharing options...

Will attempt to make one, Dad has a compass up in the work shop. Quote Link to comment Share on other sites More sharing options...
