Prevost Air Hose Quick Safety Coupler

By pushing the button on a Prevost Air Hose Quick Safety Coupler, one can-with one hand-more easily connect and disconnect any compressor-powered tool. The device bleeds off the air slowly in disconnection plus stops leaky hose connections. Prevost couplers reportedly purge the air on everything down line so there’s no hose whipping or sudden pressure releases.

Cost: $25-$50 each, depending primarily on plug circumference
