Permatex 81409 High Temp RTV Silicone Gasket, 11 Oz, Red

Permatex High-Temp RTV Silicone Gasket is a single component, room temperature vulcanizing gasketing compound designed to provide reliable “formed-in-place” gaskets for mechanical assemblies. This material cures on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. The product resists aging, weathering and thermal cycling without hardening, shrinking or cracking. Designed to maintain maximum performance in a continuous temperature environment of 600°F. OEM Specified.
