At Corvair1, we only sell one type of gaskets: the best ones. No second choices that are not up to standards. All our gaskets are top of the line, made in the USA to Corvair specifications. These are the gaskets I have been using in my own rides, as well as customers',for many years. Most of them are thicker than the average ones out there, for better seal and performance. Note that often good gaskets can leak due to use of improper sealer. Many people use silicone, and too much of it, thinking that will stop any leak. That can actually make it worse. There are many types of sealers out there, some claim to be specially designed for gaskets, some will be real hard to remove when time comes to replace gaskets; my personal preference for sealer is lithium white grease, I would say it works awesome! and a little dab does the job. Our seals are some of the best ones, we offer choices of material when available: original polyacrylate and viton, the preferred choice for many....don't hesitate to call Rafee at 918-413-1548 with any questions you might have.
Avoid this silicone mess!!! LOL!
