Smc Pneumatics KQ2T04-02AS Male Branch Tee 4mm 1/4 Bspt

Product Description

The SMC PNEUMATICS KQ2T04-02AS is a push-to-connect male branch tee tube fitting designed for pneumatic plumbing systems in light industrial and mechanical applications. It accepts 4mm outside diameter tubing and connects via a 1/4-inch BSPT male thread, delivering a maximum working pressure of 145 psi. The body is brass with polybutylene contact components, balancing corrosion resistance with secure tube retention. Licensed plumbers, mechanical contractors, and pneumatic system technicians install this fitting where a single male-threaded port must branch into two tube runs without additional adapters or manifold hardware.

This fitting is suited for compressed air distribution, pneumatic control circuits, and fluid conveyance lines operating within a temperature range of 23 degrees F to 140 degrees F. Its compact overall length of approximately 1.44 inches (36.5 mm) makes it practical in tight panel or manifold installations. The push-to-connect design reduces assembly time compared to compression or flare fittings, making it a common choice in OEM machine builds and field service work on pneumatic control panels.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion for 4mm OD tubing
• Male branch tee configuration splits one threaded port into two tube outlets in a single fitting
• Rated to 145 psi maximum working pressure for standard pneumatic service
• Brass and polybutylene construction for durability and moderate chemical compatibility
• 1/4-inch BSPT male thread for direct port mounting into BSPT-tapped manifolds or valve bodies
• RoHS compliant materials

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic systems using 4mm OD tubing and 1/4-inch BSPT ported components. Verify thread form compatibility before installation, as BSPT threads are not interchangeable with NPT threads.

Installation Notes

Installation is performed by mechanical contractors or pneumatic system technicians. Depressurize and lock out the air supply before removing or installing any fittings. Confirm the mating port is tapped to BSPT specification, as BSPT and NPT threads share similar dimensions but are not compatible. Insert tubing fully until it bottoms against the fitting stop to ensure a leak-free connection; use the fitting collar to release tubing during disassembly.
