## Overview

J-B Weld 32329 Ultimate Black RTV Silicone Gasket Maker & Sealant is a professional-grade, room temperature vulcanizing silicone designed for automotive and mechanical assemblies. It creates a durable, waterproof, and oil-resistant gasket that withstands intermittent temperatures up to 500°F. Trusted by mechanics and DIYers alike, it bonds strongly to metal and rubber surfaces without shrinking or cracking, ensuring leak-proof performance in demanding environments.

## Description

J-B Weld Ultimate Black Gasket Maker & Sealant is an RTV (Room Temperature Vulcanized) Silicone gasketing material designed for use in mechanical assemblies where maximum petroleum and oil resistance is required. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof, gasket and seal on most surfaces. It will not shrink or crack, resists oil and petroleum products, resists weathering, is sensor safe, has good temperature resistance up to 500 F intermittent and is great for many automotive applications.

Review: Very very good - 100% recommend. I bought this off the back of a chat with AI on the best silicone sealer for a new Scorpion GPF back exhaust. Couldn’t be happier with the seal. I made 2 rings, approximately 2-3mm thick inside the female end of each of the 2 connecting pipes for my i20n. Formed a complete seal and have half of it left, which probably won’t be used. No air leaks, no smell or burning. I did give it around an hour to set/ cure after putting bits of the car together having rented a ramp for 6hrs (fit other bits too). On initial startup underneath the car there was zero burn off or smells etc. Highly recommend the copper silicone version.
Review: Good liquid gasket - Used to replace an SV’s gasket gone bad - clear instructions and good technique stopped my leak. Still have loads left but been about a week and no fault. Ensure you buy the heat resistant version if you’re using it on engine parts.

### ⭐⭐⭐⭐ It’s great, I think?
*by I***N on 27 June 2025*

Never used this stuff before or anything like it. Been rebuilding an engine from scratch for the first time. Surprisingly easy to apply, considering reviews of anything like this said it was hard to apply. Bit like icing a cake a suppose. As for whether it does the job well, smells bad and dries quick, I I’ve nothing else to compare it to but I was happy with the result so far. Let’s hope the engine is sealed as it should be.
