MADE IN THE USA!

Percy's Reusable Flange Gaskets are multi-layered and made of a special "DEAD SOFT" aluminum, which conforms to header flanges for an ultimate seal. Because the SEAL-4-GOOD is a solid metal gasket, it will not blow-out nor will it burn-out.
The "SEAL-4-GOOD" header gaskets are now available for most popular applications.

Testimonial

"It was good to see Percys sign on with the USAR Pro Cup Series. Last year I
wrecked a car at IRP, it bent the header flange on the engine and I could not afford to
replace the headers. I found the Percys aluminum gasket at a local auto parts store
and was able to reseal the headers to the engine. I ran this gasket set in the
remaining races of the season and will continue to run Percy's HP Products. Thanks,
Greg Van Alst Van Alst Motorsports #35 Northern Division "

"I recently purchased your aluminum flange gaskets for my Camaro. I had blown out my paper gaskets and am happy to tell you that your product sealed nicely and I know will not bow out on me. If you have a decal of your company I would like to display it on my car. Thanks again for making a great product.”
- Eric Bayne

"Simply put, the best header & collector gaskets made! Installed header gaskets on my small block Chevy after other brands failed. Problem solved. Do yourself a favor & buy these gaskets the first time & be done with it!!! "
-Art Rowe
