Dependable, leak-free connections for air and light fluid lines. The Foster 2302S/SH is a 303 Stainless 1/8" coupler 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 plugs. 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 superior corrosion resistance for washdown, marine, and chemical environments.
  • Stainless ball locking — which means a large number of captive balls spread the load for positive, swiveling connections that resist wear and reduce hose torque.
  • Viton seal — which means reliable sealing in elevated-temperature and hot-fluid 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 — 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 plug 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 Viton seal rated -40°F to +300°F (Viton, heat).

Can it handle hot air or hot water?
Yes — this variant uses a Viton seal selected for elevated-temperature and hot-fluid service.

How does it connect?
The 2 Series socket uses a manual pull sleeve — retract the sleeve by hand to connect or release the plug. The socket is valved (one-way shut-off), so install it on the pressure side; the supply line seals when the plug is removed.

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