Gasket Sealants

Permatex® Hi-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 deg F.

Permatex® ultra Gray® gasket maker 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 perform under the higher load conditions of engines with closely spaced bolt patterns (typically non-US designed) and maintains outstanding oil, water-glycol resistance.

Ultra Black® ensures extended drivetrain warranty compliance. Fast curing formula. Sensor safe, low odor, non-corrosive. Meets performance specs of OE silicone gaskets. Retains high flexibility, oil resistant properties through use of a patented adhesion system. Temperature range -65 to 500 deg F intermittent, resists auto and shop fluids and vibration.

Permatex® Ultra Copper® 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. Permatex® Ultra Copper® is the most advanced high performance, high temperature (up to 700 deg F intermittent) RTV gasket available.

Designed specially for high torque and high vibration applications, like those common in import engines, this premium RTV gasket maker exceeds manufacturers performance requirements. Sensor safe, low odor and non-corrosive. Maximum vibration resistance, with outstanding resistance to oils, cooling and shop fluids. Guaranteed not to leak. Temperature range -65 to 500 deg F intermittent.
