Why this plug

  • Brass 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 1/2" 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 1/2"-body industrial-interchange coupler (ISO 6150-B / ANSI T3.20.14), the most common high-flow 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 rated -40°F to +250°F.

Is this air coupler fuel-rated?
No — the 5 Series is an industrial air/fluid coupler for compressed air, water, and similar media; it is not rated for fuel.

Ideal for high-flow shop air lines, pneumatic tools, and production equipment. Pair this plug with a matching 1/2" 5 Series coupler for a complete, leak-free connection.
