Gasket Sealant FAQ


Gaskets are used to prevent leakage of fluids or gases by forming impervious barriers. For successful gasketing, the seal must be able to withstand the operating temperatures and pressures to which it is subjected, and must remain intact and leak-free over a long period of time.


LOCTITE® gasketing products are self-forming gaskets that provide a perfect seal between components, with maximum face-to-face contact, eliminating flange face corrosion. A low pressure seal is formed immediately on assembly and, at full cure, it provides a seal that won’t shrink, crack or relax.

LOCTITE gasket & flange sealants can provide up to 95% material savings over hard gaskets while offering flexibility in design, allowing for lower cost manufacturing methods.
