Smc Pneumatics KQ2U10-03AS Y-connector Fitting 10mm 3/8 Bspt

Product Description

The SMC PNEUMATICS KQ2U10-03AS is a push-to-connect Y-connector tube fitting designed for pneumatic and fluid distribution lines. It accepts 10mm outside-diameter tubing and connects via a 3/8-inch BSPT threaded port, allowing a single line to split into two branches without tools on the tube side. The body is brass with polybutylene components, rated for a maximum working pressure of 145 psi. Operating temperature range runs from 23 degrees F to 140 degrees F. This fitting is installed by pneumatic system technicians, pipefitters, and industrial maintenance mechanics working on compressed-air or low-pressure fluid circuits.

The KQ2U10-03AS is suited for light industrial, commercial, and OEM pneumatic assemblies where a compact, tool-free tube connection is needed at a branch point. The BSPT thread type is common in international and OEM equipment. Typical applications include instrument air lines, pneumatic actuator supply circuits, and process control tubing runs where space is limited and quick-change serviceability is valued. This fitting handles moderate-pressure compressed air and compatible fluid media within its rated temperature and pressure envelope.

Key Features

• Push-to-connect design allows tube insertion without additional ferrules or tools on the tube end
• Y-configuration splits one supply line into two branch outlets in a compact form factor
• Brass body with polybutylene components for compatibility with compressed air and light fluid service
• Rated to 145 psi maximum working pressure
• BSPT threaded port matches international and OEM equipment standards
• RoHS compliant construction

Compatibility

Designed for use with 10mm outside-diameter push-to-connect tubing and 3/8-inch BSPT threaded ports on pneumatic manifolds, valves, and equipment fittings within the rated pressure and temperature limits.

Installation Notes

Depressurize and lock out the compressed-air circuit completely before removing or installing any fitting. Hand-tighten the BSPT threaded end and apply appropriate thread sealant compatible with the media and operating pressure per system requirements. Insert tubing fully until it bottoms out in the collet to ensure a secure, leak-free connection. To release tubing, depress the collet ring and withdraw the tube while the line remains depressurized.
