The SMC PNEUMATICS KQ2H08-U02A is a push-to-connect tube fitting connector designed for fast, tool-free pneumatic line connections. It accepts tubing with an 8 mm outside diameter and features a 1/4 inch universal thread for wide compatibility across pneumatic systems. Rated to 145 psi maximum working pressure, this fitting is constructed from brass with a polybutylene tube contact body and is RoHS compliant. The overall installed length is 18.50 mm. HVAC and plumbing technicians working with compressed air lines and pneumatic control circuits rely on this style of fitting for quick, secure connections in tight spaces.
This fitting is suited for pneumatic tubing runs in light industrial, commercial HVAC, and mechanical systems where push-to-connect convenience is required. The universal thread type makes it adaptable to a range of ports and manifolds without requiring thread-type-specific adapters. Its white coloring aids visual identification in multi-line installations. Typical applications include control air circuits, instrument air tubing, and pneumatic actuator supply lines.
Designed as an OEM-style replacement or upgrade fitting for pneumatic systems using 8 mm outside diameter tubing and 1/4 inch universal thread ports.
Installation is typically performed by licensed HVAC technicians or mechanical tradespeople working on pneumatic control systems. De-pressurize and lock out the pneumatic circuit before installing or removing any fittings. Ensure tubing is cut squarely and deburred before insertion to achieve a proper seal. Verify that the thread type and size match the receiving port before assembly.
