Smc Pneumatics KQ2T04-01AS Male Branch Tee Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2T04-01AS is a push-to-connect male branch tee tube fitting designed for pneumatic plumbing and fluid distribution applications. Constructed from brass with a polybutylene tube insert, this fitting accepts 4 mm outside-diameter tubing and connects to a 1/8 BSPT male threaded port. It handles a maximum working pressure of 145 psi and operates across a temperature range of 23 degrees F to 140 degrees F. The compact design with an overall length of 31 mm makes it well suited for instrument panels, pneumatic manifolds, and tight-cabinet installations. Licensed technicians and pneumatic system integrators are the typical installers.

This fitting is used in compressed-air and low-pressure pneumatic circuits found in industrial automation, HVAC controls, and process equipment. The male branch tee configuration allows a single inline threaded port to branch a tube run into two directions, reducing the need for additional adapters or block manifolds. Its RoHS-compliant brass body suits clean-air and dry-gas service, and the push-to-connect mechanism supports fast, tool-free tube insertion during panel builds or field service.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Brass body with polybutylene tube contact surface for corrosion resistance in dry-air service
• Rated to 145 psi maximum working pressure
• Accepts 4 mm outside-diameter tubing
• 1/8 BSPT male thread for direct port connection
• RoHS compliant construction

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic systems using 4 mm outside-diameter tubing with 1/8 BSPT threaded ports, consistent with KQ2 series plumbing configurations.

Installation Notes

Depressurize and lock out the pneumatic system completely before removing or installing any fittings. Ensure the mating port threads are clean and that thread sealant appropriate for BSPT connections is applied before tightening. Insert tubing fully until it bottoms out in the collet to achieve a proper seal. Verify the installed assembly holds pressure before returning the system to service.
