Description

It is sensor-safe, low-odor, and non-corrosive, ensuring it will not contaminate oxygen sensors or damage sensitive electronic engine components. Featuring a high-rigidity paste consistency, this gasket maker is ideal for components with closely spaced bolt patterns. It is specifically formulated for use on high-torque and high-vibration engine components, including valve covers, water pumps, intake manifold end seals, and thermostat housings. It maintains a temperature resistance range of -54°C to 260°C (-65°F to 500°F). For best results, allow the material to reach a full 24-hour cure time before returning the component to service.
