Why this coupler

  • Sleeve Guard — which means a rigid flange at the nose shields the sleeve from accidental retraction when the hose is dragged over an obstacle.
  • 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 3/8" flow, no drips, no hiss. Built to take daily shop abuse and keep sealing leak-free, connection after connection.

Frequently asked questions

What does this connect to?
It mates with any 3/8"-body industrial-interchange plug (ISO 6150-B / ANSI T3.20.14) — the most common air-coupler standard in North America.

What pressure and temperature is it rated for?
300 PSIG working pressure (vacuum to 27" Hg connected), with a Buna-N (Nitrile) seal.

What is a Sleeve Guard?
A rigid flange at the nose of the socket that protects the sleeve from being knocked open when the hose is dragged, reducing accidental disconnects.

Ideal for shop air lines, pneumatic tools, impact wrenches, and production equipment. Pair this coupler with a matching 3/8" 4 Series plug for a complete, leak-free connection.
