Red Hi-Temp RTV Silicone Gasket Maker, 8 oz

Dynatex 143374 is Dynatex® Red Hi-Temp RTV Silicone Gasket Maker in an 8 oz automatic can. This one-component, non-sag silicone cures with ambient moisture to form a tough, flexible, leak-proof gasket that is oxygen-sensor safe and manufactured to meet OEM requirements. Fully cured, it withstands extended service at temperatures up to 650 °F (343 °C) and resists oil, water, antifreeze, transmission fluid, thermal cycling, and vibration—ideal for high-heat engine, transmission, and exhaust assemblies in automotive, heavy-duty, marine, and industrial equipment.
