Review on 🔧 Permatex 54540 Pneumatic and Hydraulic Sealant - The Ultimate Solution for Air and Fluid Systems - 1.22 oz. by Cre Soto

Ideal for the air fittings on my air tools/compressors. I have a 29 gallon port cargo that may leak significantly overnight. This slowed the leak, but the hiss was still audible. The plug for the check valve thread was raw to say the least. I used teflon tape, pipe lube and got it. I had to use a black RTV because the threads were very poorly made. On the other hand, I've used it for my air tool fittings and hoses and it works great. A little goes a long way, I honestly think it will last for years if it doesn't dry inside.
