Description:

Specially formulated for cooling system repairs, the Permatex 22071 Water Pump and Thermostat RTV Silicone Gasket delivers reliable sealing performance in demanding automotive environments. This sensor-safe, non-corrosive RTV silicone is engineered specifically for use on water pumps and thermostat housings, providing exceptional resistance to water and glycol-based coolants.

Designed with superior adhesion and long-lasting flexibility, this RTV silicone can be used both as a gasket maker and a gasket dressing, ensuring leak-free seals even on irregular or imperfect mating surfaces. Once cured, it forms a durable, flexible seal that withstands vibration, thermal expansion, and pressure changes commonly found in engine cooling systems.
