Hylomar Advanced Formulation Gasket & Jointing Compound, 85 g, Blue

Hylomar Advanced Formulation is a solvent-free, non-setting, non-hardening gasket and jointing compound, supplied in an 85 g (3 oz) tube. It functions as a gasket dressing and flange sealant, applied as a mobile compound that fills and seals surface imperfections in flange faces rather than forming a set film. Because it does not set or harden, parts can be assembled immediately or left indefinitely before jointing, and the compound can be removed from dismantled components with an acetone-soaked cloth without scraping. It resists most automotive fluids and many other chemicals, as well as joint vibration, shock, and differential thermal expansion, and operates from -55°C to 250°C (-67°F to 482°F).
