Review on 🔧 Tailonz Pneumatic Push Pull Valve 4R210 08 for Optimal Operation by Randy Bin

Like that, but previously applied Teflon pipe impregnation looks like cement. I got 1 engagement thread before I became uncomfortable applying more torque. I soaked dope in acetone for an hour and it softened. Hit it with a small flathead screwdriver to peel off the first layer and let soak for another hour. The rest was removed with a brass brush. I used regular teflon tape and got regular thread engagement. Pressure relief fittings have severe fitting size limitations. I see them running at 1/4 NPT where they don't release large amounts of pressure but when using them on a 100mm x 150mm pneumatic cylinder I feel they slow down the piston speed significantly and also make a lot of noise (would probably happen independently). Instead, I chose to use plastic tubing to reduce pressure drop and route it to minimize noise.
