Dependable, leak-free connections for air and light fluid lines. The Foster PJ8-2S/S is a 303 Stainless 1/8" plug from the proven Foster 2 Series — a miniature, high-flow quick coupler only 5/8" in diameter (socket ~1 oz) that interchanges with Foster 1/8" 2 Series couplers. Built in the USA for shops, hobbyists, and OEMs that need a compact coupler without giving up flow or durability.

Why this coupler

  • 303 Stainless construction — which means it withstands repeated high-pressure cycling without deforming.
  • Precision leak-proof seal — which means bubble-tight performance within the rated working pressure.
  • 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 — no drips, no hiss, no fighting a stuck sleeve. Drop it into a tight panel or a crowded bench and the compact 5/8" body stays out of the way while still flowing like a larger coupler.

Frequently asked questions

What does this connect to?
It mates with any Foster 1/8" 2 Series coupler of the same body size. The 1/8" 2 Series is Foster’s miniature industrial profile.

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 (Buna-N).

Is this air coupler fuel-rated?
No — the 2 Series is a miniature air/fluid coupler for compressed air, water, and similar low-pressure media; it is not rated for fuel.

Which side does the plug go on?
The plug is un-valved and exhausts the downstream line at disconnect, so the matching valved socket installs on the pressure side.

Ideal for lightweight, low-flow applications — airbrushes, small pneumatic systems, hobby and craft tools, instrument air, and compact shop setups. Pair this plug with a matching Foster 1/8" 2 Series coupler for a complete, leak-free connection.
