Prevost Kit - 1/2" Female NPT High Flow Safety Disconnect & 1/2" Male Air Plug (for use with 1" Drive Impact Tools) - Facom and other manufacturers of 1" drive Impact tools typically spec a 1/2" NPT male plug for use in the tool and recommend a coupler capable of 100+ CFM air flow on the end of your supply hose. This hose should have an inside diameter of 1/2" or 3/4" with end fittings of at least 1/2" NPT. This kit flows an incredible 183 SCFM of air at 100psi. For use with 1/2" Industrial Interchange air plugs (IRP11 series).

Safety coupling has a 2 stage disconnect (you must do both steps to release the tool/air plug)....

(1) Pulling back on the coupler releases the downstream air pressure making the hose safe.

(2) Pushing forward on the coupler then releases the plug from the coupler

For use with high capacity pneumatic tools (truck impact wrenches, jackhammers, pnematic pumps, etc) and for irrigation contractors running larger diameter hoses to blow out sprinkler systems.

Note on Thread Size - Thread Size (NPT) does NOT refer to the physical dimension of the pipe or fitting. Please refer to the table below if you're unsure of which size to buy. For example, a 1/4" NPT pipe thread (common air tool fitting size) has an outer diameter of 0.540".

Outside Diameter (OD/inches) = Pipe Thread Size (NPT)

• 13/32 (.405") = 1/8" NPT
• 35/64 (.540") = 1/4" NPT
• 43/64 (.675") = 3/8" NPT
• 27/32 (.840") = 1/2" NPT
• 1-3/64 (1.050") = 3/4" NPT
