Review on ColorConnex Coupler Plug Piece Industrial by Marcos Fiallo

I've had the exact same set for 3 years, no air leaks and no issues. I've recently moved and need a lot more for my modernized workshops with a few necessary catenaries. I bought these as the price and quality are great and from previous experience. Now I have 6 different clutches in different areas in my wood shop and in my auto repair shop. I keep my air at 90psi and have no air leaks from the clutches and they all work fine. I really don't understand the bad reviews regarding the air leak. My only guess is that people don't put tape on threaded leads. 2 to 3 wraps of pipe tape and a good fit are a must for any coupling to be installed. I've used and used my 3 year old set quite a bit and it's still holding up as good as the day I bought it with my first Zilla flexible air hose. Both are made by the same company and the quality is excellent!
