1/4\" Flow S1 Safety Coupler-3/8\"NPT Female (\"High Flow\" Profile)

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.

Technical features of this coupler include........

  • 1/4" Flow (37.7cfm)
  • European High Flow Profile
  • Nitrile seals for leak free connections
  • Stainless steel spring
  • Impact resistant plastic composite body
  • 175psi working pressure
  • Push to connect
  • Push button disconnect

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
