Getting confused
That rubber pictured above in the Ebay ad is not a seal. It is a retainer. The little groove you see in the retainer is so it collapses to get it in the master cylinder They can only be used once. You put that in the master cylinder and then push the rod in using dawn regular brand dishwashing liquid the same Dawn you rub down the inside of slicks with to seal them. Any other lube ruins it. It will rot . Once the retainer is installed properly you should not be able to pull the push rod out without extreme force. Remember once you pull this rod out the retainer is junk you need a new one. Ebay is the cheapest I buy them in bulk. They are not pure rubber like a hose they are a polymer
