Prevost "High Flow"
2-stage safety coupler - 1/4" flow body with 3/8" NPT
female end. Recommended for use at the wall drops in a plumbed
air distribution system (or as the main connection point on a
portable compressor). The first push of the button on the side of
the coupler bleeds the air from the load (the hose and air tool).
The second push releases the hose from the coupler.
"Push-button" Quick Couplers are great for any shop
that uses compressed air.
I recommend the 1/4"
flow bodies for smaller systems and at the ends of your
(1/4", 5/16" or 3/8" id) air hoses. This European
High Flow profile uses a threaded plug (male for tool bodies,
female for hose connections) which flow approx 33% more volume vs
standard Industrial or Truflate profiles. See photo1 and photo 2. Recommended for paint shops....sanders
and grinders have higher CFM requirements compared to standard
impact tools. These couplers MUST be used with the matching
"High Flow" plugs.

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