Description
LOCTITE High Flex Gasket Maker Flange Sealant (Part No. 555354) is a form-in-place gasketing paste engineered to deliver a resilient, solvent- and temperature-resistant seal between close-fitting rigid metal flanges.
Unlike precut gaskets, this flexible gasket maker adapts to flange movements caused by vibration, pressurization, and thermal expansion, maintaining seal integrity under demanding operating conditions. Its high flexibility and durability make it an effective alternative where conventional gaskets may fail or degrade over time.
LOCTITE High Flex Gasket Maker is ideal for forming gaskets on pumps, housings, axle covers, gear cases, split crankcases, and similar assemblies. It can also be used to repair damaged conventional gaskets or as a coating/dressing to enhance the sealing performance of existing gaskets.
Supplied in a 50 ml tube, it is well suited for maintenance, repair, and OEM assembly tasks requiring reliable, long-lasting sealing performance.
