Industrial Grade Gasket Sealant 10.15 oz

LOCTITE 475372 is a clear, room-temperature vulcanizing paste designed for gasket sealing on glass, metal, plastic and wood. It resists oil and remains non-sagging during application, making it suitable for automotive and industrial assemblies that require a flexible, durable bond.

Check material compatibility and cure schedule

Verify that the mating surfaces are glass, metal, plastic or wood and that the joint will see oil exposure rather than other fluids. The product requires a full day to cure at room temperature and provides a 45-minute working window, so plan assembly sequences accordingly.

Sustained temperature and oil resistance

Once cured, the sealant maintains integrity across a continuous range from -60 to 400 degrees F. Its non-sagging paste form resists oil degradation over long service intervals without slumping or losing adhesion in the joint.

Questions about this item

Does the 10.15 oz cartridge come with a nozzle or do I need a separate caulk gun?

The product is supplied as a cartridge only; a standard caulk gun and a cut-to-size nozzle are required for application.

How do I decide between the SI 9160 series and other Loctite gasket sealants?

Choose the SI 9160 series when you need a clear, non-sagging RTV paste rated for -60 °F to 400 °F that resists oil on glass, metal, plastic and wood.

What does the 400 °F maximum temperature mean once the sealant is cured in an engine?

After the full 1-day room-temperature cure, the sealant maintains its bond and oil resistance continuously up to 400 °F in service.
