Smc Pneumatics KQ2U13-36AS Y-connector Fitting 1/2 in Od

Product Description

The SMC PNEUMATICS KQ2U13-36AS is a push-to-connect Y-connector tube fitting designed for pneumatic and fluid distribution systems. It splits a single line into two branch lines without tools, using a push-in collet mechanism to secure tubing rated at 1/2 inch outside diameter. The body is constructed from brass with polybutylene components and is rated for a maximum working pressure of 145 psi. This fitting is suited for compressed air, light fluid, and pneumatic control lines in industrial and mechanical service environments. Licensed plumbers, pipefitters, and pneumatic technicians are the typical installers.

This Y-connector is used in pneumatic distribution manifolds, compressed air supply lines, and fluid control circuits where a single supply must branch to two downstream points. The 3/8 inch NPT thread connection allows integration into standard threaded port blocks and manifolds. Its compact form factor, with an overall length of approximately 2.16 inches (54.80 mm), makes it suitable for panel-mount and tight-clearance installations in both light industrial and commercial mechanical systems.

Key Features

• Push-to-connect collet design - no tools required for tube insertion
• Y-configuration splits one inlet into two branch outlets
• Brass body with polybutylene components for corrosion resistance
• 145 psi maximum working pressure rating
• 3/8 inch NPT threaded port for standard manifold compatibility
• RoHS compliant construction

Compatibility

Designed as an OEM-style replacement or direct-install fitting for pneumatic and fluid distribution systems accepting 1/2 inch OD tubing and 3/8 inch NPT threaded ports.

Installation Notes

Installation is typically performed by a licensed pipefitter, pneumatic technician, or plumber. Depressurize and isolate the line fully before removing any existing fitting or inserting this connector. Ensure tubing is cut cleanly and squarely, and that the tube is inserted to full depth before pressurizing. Verify that system operating pressure does not exceed 145 psi and that ambient temperatures remain within the rated range of 23 degrees F to 140 degrees F.
