Why this plug

  • Steel construction — which means it withstands repeated high-pressure cycling without deforming.
  • 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 coupler (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.

Is this air coupler fuel-rated?
No — the 4 Series is an industrial air/fluid coupler for compressed air, water, and similar media; it is not rated for fuel.

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