1DFAUL RTV Silicone Gasket Maker, 170 g High-Temp Oil-Resistant Sealant

High-temperature RTV silicone forms a flexible seal to help close gaps between metal mating surfaces. Its oil-resistant, waterproof formula is designed for automotive sealing work. Use it to form a gasket for an engine or gearbox, or for applications such as pumps and axles. It offers a formed-in-place alternative to cutting a gasket when the job calls for sealant applied directly to the joint.

Tips for day-to-day use

For a consistent seal, clean oil from the surface before applying the silicone, then spread it evenly across the joint. During curing, apply pressure so the RTV can fill gaps between the surfaces. Once the seal is made, carry out a sealing test before returning the equipment to use. Curing time can vary with the conditions, the listed full cure time is 28 minutes, and the guidance for room temperature gives a range of 10 to 30 minutes. Avoid contact with uncured sealant.

The clear liquid comes in a tube and is intended for metal surfaces. Its stated application temperature range is -60 to +300°C. The high-temperature and oil-resistant properties make it relevant to joints exposed to automotive fluids and heat, while its waterproof and antifreeze properties support sealing needs across changing operating conditions. Rather than relying on a pre-cut gasket, this product lets you form a silicone gasket at the joint itself.

Why it makes sense

This sealant is specified for automotive engines, gearboxes, front and rear axles, pumps, superchargers, valve covers, valve guides and oil pans. That range makes it useful for workshop jobs involving different engine and drivetrain components, as well as pump repairs. The cured silicone is described as flexible, helping it maintain a seal through vibration and temperature changes. It is also presented as non-corrosive and capable of filling small surface gaps.

Buyers describe the product as effective for a range of sealing tasks, including automotive repairs. Feedback is mixed on leak prevention, durability and application, so careful surface preparation and even coverage remain important parts of the job. You’ll like it if you need a clear RTV silicone gasket maker for metal automotive components and want to form the seal directly on the mating surface.
