Hylomar Gasket Dressing ' Flange Sealant

Hylomar Universal Blue Racing Formula Gasket Dressing & Flange Sealant from Permatex is a non-chlorinated, gel-based sealant especially formulated to remain flexible and tacky after application, even when exposed to high engine temperatures. Designed for use with pre-cut gaskets and head gaskets, Hylomar's sealant can also be used as a sealant for machined flanges and threaded parts. The non-setting, non-hardening formula allows repeated assembly and disassembly without the need to apply more sealant.
