## Description

J-B Weld MufflerSeal Muffler Cement Plastic Tube 6 oz. (37906)

Review: Before paying big bucks for a new muffler a little of this may be all that you need! - This stuff worked great! If you have the luxury of a little extra time or a heated garage or heat gun I’d take advantage of it because it does take more time than one might think for it to cure. I pretty much used a whole tube (smaller size order option) but I also laid it on thick around the collar area where the muffler meets the exhaust. I live in the northeast so it’s been cold and I wanted the extra strength for the long winter complete with caustic road salts, moisture and frost heaves. It was a great fix to get me over the hump until spring! J-B Weld is a great company with great products!
Review: Used on 3in 94 k1500 exhaust, worked great. 350sbc - Worked great for my application however, it cracks on moving joints. Still sealed my exhaust very nicely.

### ⭐⭐⭐⭐⭐ Works great for muffler repairs
*by C***N on September 4, 2025*

Used this J-B Weld MufflerSeal to fix a small leak in my car’s muffler, and it worked really well. The cement is thick and easy to apply, and it sets up quickly. Once it cured, the leak was completely sealed and it’s holding up perfectly even under heat and vibration. Definitely a good, affordable solution if you need a quick muffler repair without replacing the whole part.
