Smc Pneumatics KQ2Y04-M6A Male Run Tee Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2Y04-M6A is a push-to-connect male run tee tube fitting designed for pneumatic plumbing and fluid conveyance applications. It accepts 4mm OD tubing and terminates with an M6 x 1 male threaded port on the run, allowing a branch connection to be added inline without additional fittings or tools for the tube side. The body is brass with a polybutylene tube-retention collet. Rated to 145 psi maximum working pressure, it handles typical plant-air and low-pressure pneumatic circuit pressures found in automation and instrumentation lines. Licensed HVAC, automation, and instrumentation technicians regularly specify this fitting when routing control-air or pilot lines in tight panel spaces.

This fitting is suited for light industrial and OEM pneumatic plumbing where 4mm tubing is the standard line size. Typical install scenarios include instrument air distribution manifolds, solenoid valve pilot supply lines, and small-bore pneumatic control circuits operating within the rated temperature window of 23 degrees F to 140 degrees F. Its compact overall length of approximately 1.23 inches (31.2 mm) makes it practical in space-constrained enclosures and machine frames.

Key Features

• Push-to-connect design accepts 4mm OD tubing without tools for fast, repeatable assembly
• M6 x 1 male thread on the run port for direct panel or manifold mounting
• Brass body construction provides corrosion resistance in typical compressed-air environments
• 145 psi maximum working pressure suitable for standard plant-air and pilot-line service
• RoHS compliant for use in environmentally regulated equipment
• Compact 31.2 mm overall length fits tight enclosures and machine frames

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic systems using 4mm OD tubing and M6 x 1 threaded ports. No specific compatible model numbers were provided in the product data.

Installation Notes

Depressurize and bleed the pneumatic circuit completely before removing or installing any fittings. Cut tubing squarely and deburr the cut end before insertion to ensure the collet seats and seals correctly. Verify the M6 x 1 thread pitch on the receiving port before installation to avoid cross-threading. To release tubing, press the collet ring inward while pulling the tube free.
