Anaerobic 518 Flange Sealant, 50Ml

PERM51813 Anaerobic 518 Flange Sealant (50 ml) is a noncorrosive anaerobic gasket maker designed for sealing aluminum, iron, and steel flanged mating surfaces when you need a reliable seal—especially when a conventional gasket is missing, delayed, or has decided it’s retired. It fills gaps up to 0.015 in, cures to a solvent-resistant seal that won’t tear or decay in service, and still allows easy disassembly even after extended use.
