22071 Water Pump & Thermostat Housing Gasket Maker, Rtv Silicone, 0.5 Oz.

Permatex 22071 is a noncorrosive, sensor-safe RTV silicone gasket material formulated specifically for water pumps and thermostat housings. This specialized sealant delivers the highest water-glycol resistance available in an RTV silicone, making it particularly effective for sealing engine cooling system components that experience constant moisture exposure.

This RTV silicone forms a tough, flexible rubber gasket that resists aging, weathering, and thermal cycling without hardening, shrinking, or cracking. Unlike rigid gaskets that can fail under stress, the flexible formula maintains performance across a temperature range of -65°F to 500°F intermittent, accommodating the temperature fluctuations common in engine applications. The 0.5 oz tube provides a convenient size for on-the-spot sealing and repair work.
