Review on High-Quality Quafwia Aluminum Camlock Fittings Coupling for Industrial Applications by Cho Screeton

These fittings worked great on my Harbor Freight 2" semi-trash pump. I wanted to upgrade the inlet and outlet connections and they worked fine. Well constructed. The only problem I had I had and it might be a charge pump in the port, the threads were very tight. I hand tightened it the first time and it got stuck and I had to use a wrench to remove the fitting which damaged the first few threads i ended up using a file to lightly file the threads to make the fitting complete can be set up.
