Sanvo Black Super RTV Silicone Gasket Maker 93g

Sanvo is a manufacturer of industrial adhesives, sealants, and maintenance chemical products for automotive and industrial maintenance applications. Their range includes RTV silicone gasket makers, thread sealants, and chemical maintenance products designed for use in engine assembly, gearbox repair, and general industrial equipment sealing.

Sanvo RTV (Room Temperature Vulcanising) silicone gasket maker is used to form in-place gaskets on mating surfaces in engine, gearbox, and equipment assembly. Applied to one mating face before assembly, it cures on contact with atmospheric moisture to form a flexible, oil-resistant seal that conforms to surface irregularities and eliminates the need for cut paper or cork gaskets.

Where this product is used

RTV silicone gasket maker is used across engine and equipment assembly and repair:

• Engine sump, rocker cover, and timing cover reassembly where pre-cut gaskets are unavailable or have been replaced by RTV.
• Gearbox and differential housing sealing where oil resistance and temperature flexibility are required.
• Industrial equipment and pump casings where flat mating surfaces require a formed-in-place seal.

Selecting the right option

Ensure surfaces are clean, dry, and free of old gasket material before applying. Apply a consistent bead around the bolt hole pattern and mating surface perimeter. Allow the stated cure time before filling with fluid or applying load. Check the temperature rating — standard RTV suits most automotive applications; high-temperature formulations are required for exhaust manifolds and turbo housings.
