Sensor-Safe Blue RTV Silicone Gasket


The original Permatex blue makes reliable “formed-in-place” gaskets that resist shrinking, cracking and migrating. Product cures to a strong, flexible rubber that seals flanges against leakage and resists oil and other shop fluids. Coat pre-cut gaskets to increase reliability. Temperature range -65°F to 500°F (-54°C to 260°C) intermittent. Low volatility. Fills gaps to .25″ when fully cured.
