Built in the USA for demanding shop air, tools, and production lines.

Why this coupler

  • Automatic push-to-connect — which means single-handed connection with no sleeve retraction, for faster cycle times.
  • Brass construction — which means corrosion resistance and smooth, reliable operation.
  • EPDM seal — which means compatibility with steam service.
  • One-Way Shut-Off — which means the socket seals the supply line the instant the plug is removed, holding pressure and preventing blow-down.

Snap it on and the connection just holds — full 1/2" flow, no drips, no hiss. Built to take daily shop abuse and keep sealing leak-free, connection after connection.

Frequently asked questions
