Durable and Versatile – Excellent Gasket Maker for Oil Resistance
The RTV silicone gasket maker is an excellent product for sealing engine parts that need maximum oil resistance. I’ve used it for valve covers and oil pans, and it has held up perfectly under harsh conditions, even with high temperatures and constant exposure to oil. The application is straightforward, and it forms a strong, durable seal that doesn’t leak once cured. It dries quickly and provides a solid, long-lasting bond that is resistant to oil, water, and other fluids. Overall, it’s a high-quality gasket maker that does exactly what it promises. Perfect for anyone needing a reliable sealant for automotive or other oil-resistant applications. Highly recommend!

👍
I used it for my lower timing cover on my 2016 Volkswagen GTI and it’s been holding up for the last six months. I totally recommend this silicone. It’s easy to work with. It’s not messy and it’s durable.

This stuff is a life saver
I used this to seal the back window of my Jeep because I got mad that I couldn’t find the source of a leak……it worked perfect! Stopped the leak and it’s black, so it kinda blends in. I didn’t do a very good job putting it in, but it works! This stuff will make a seal on just about anything.
