Review on 💡 Pneumatic Connector Fittings by Ted Lele: Optimize Your Material Handling Efficiencies by John Larsen

These are really high quality connectors. They have a solid rubber seal with what appear to be stainless steel grips that retract when the trigger is pulled. The pipe thread is short and too small to be tightened enough to prevent leakage. One worked for me because I might have a little leak around threads in my application. It's a shame that so many Chinese parts fail because of non-standard pipe threads.
