Permatex 80017 Aviation Form-A-Gasket No. 3 Sealant, 16 oz. , Brown

Permatex 80017, Aviation Form-A-Gasket No. 3 Sealant, 16oz

A non-hardening gasket dressing that seals mating surfaces without ever fully setting rock hard, so gaskets stay serviceable and don't fuse the joint shut for good. Aviation-grade formulation for metal-to-metal joints, fittings, and gasket surfaces that need a reliable seal without sacrificing the ability to service them later.

Spec: Permatex PN 80017, Form-A-Gasket No. 3.

Who this is for: A&P mechanics and engineers sealing gasket surfaces and fittings during scheduled maintenance, and flight schools or owner-operators handling their own gasket work in-house.
