Review on πŸ”§ Permatex 54540 Pneumatic and Hydraulic Sealant - The Ultimate Solution for Air and Fluid Systems - 1.22 oz. by Jeff Westra

Revainrating 5 out of 5

Worked when other products didn't work.

I have been sealing threads of all kinds for many years. The fitting manufacturers I have had to use have done a very poor job with NPT threads in the Chinaum factory where they were born. This material permanently seals the threads with lightweight aviation hydraulic fluid. Worth every penny.

Pros
  • Nice packaging
Cons
  • old
