Granville Instant Gasket Silicone Sealant
Granville Instant Gasket Sealant 40g
High-performance RTV silicone for instant gasket formation and sealing.
Granville Instant Gasket Sealant is a versatile, oil-resistant RTV silicone designed to replace traditional pre-cut gaskets. It creates a tough, flexible seal that resists heat, oil, and vibration — ideal for automotive, industrial, and marine applications.
Supplied in a handy 40g tube, it’s perfect for smaller jobs such as sealing engine covers, sumps, gearboxes, and thermostat housings. Once cured, it forms a durable, leak-proof joint that remains flexible under pressure and temperature changes.
