The SMC PNEUMATICS KQ2H11-34AS is a push-to-connect tube fitting connector designed for fast, tool-free pneumatic line connections. Built from brass with a polybutylene tube-contact component, it accepts 3/8 inch outside diameter tubing and threads into a 1/8 inch NPT port. The fitting is rated to 145 psi maximum working pressure and handles temperatures from 23 degrees F to 140 degrees F. It is a compact, single-piece connector suited for plumbing into pneumatic control panels, automation assemblies, and fluid distribution lines where a reliable push-in connection is required.
This fitting is used in light industrial, commercial, and OEM pneumatic systems where 3/8 inch OD tubing must terminate at a threaded port. Typical applications include compressed air distribution, pneumatic actuator supply lines, and instrumentation tubing runs. The NPT thread form suits standard North American pipe fittings and manifold ports. At an overall length of approximately 0.95 inches (24.10 mm), it fits in tight panel and manifold installations without extending far from the port face. Installers working on automation equipment, HVAC pneumatic controls, or fluid-handling panels will encounter this fitting class routinely.
Designed as an OEM-style push-to-connect connector for pneumatic systems using 3/8 inch OD tubing and 1/8 inch NPT threaded ports.
Depressurize and lock out the pneumatic circuit completely before removing or installing any fittings. Verify the mating port thread form is NPT before installation - do not force the fitting into BSPT or other thread forms. Insert tubing fully until it bottoms out in the collet to ensure a leak-free grip. Inspect the tubing end for clean, square cuts with no burrs before insertion.
