Smc Pneumatics KQ2L11-00A Push-to-connect Union 3/8 in

Product Description

The SMC PNEUMATICS KQ2L11-00A is a push-to-connect union tube fitting designed for quick, tool-free connections in pneumatic and fluid-transfer plumbing systems. Constructed with a brass body and polybutylene components, it accepts 3/8-inch outside-diameter tubing and holds a maximum working pressure of 145 psi. The union configuration allows two tube ends to join inline without threading or soldering. Licensed plumbers, pipefitters, and pneumatic system technicians install this fitting in compressed-air lines, light hydraulic circuits, and general fluid-distribution runs where fast, repeatable connections are required.

This fitting is suited for residential, commercial, and light industrial pneumatic plumbing applications. It performs across a wide service temperature range of 23 degrees F to 140 degrees F, making it appropriate for interior mechanical rooms, equipment panels, and air-supply manifolds. The push-to-connect design speeds up installation and disassembly during service calls, reducing labor time on tight maintenance schedules. It is RoHS-compliant, making it acceptable for installations where restricted-substance requirements apply.

Key Features

• Push-to-connect union design - no tools required for tube insertion
• Brass body with polybutylene components for corrosion resistance
• Rated to 145 psi maximum working pressure
• Service temperature range of 23 degrees F to 140 degrees F
• RoHS-compliant construction
• Accepts 3/8-inch OD tubing for inline union connections

Compatibility

Designed as an OEM-style push-to-connect union fitting compatible with 3/8-inch outside-diameter tubing in pneumatic and general-purpose fluid-transfer plumbing systems.

Installation Notes

Installation is typically performed by a licensed plumber or pneumatic systems technician. Depressurize and isolate the air or fluid line completely before disconnecting or installing any fitting. Ensure tubing ends are cut cleanly and squarely with a tube cutter to achieve a leak-free seal in the push-to-connect collet. Verify the installed fitting does not exceed the 145 psi working pressure or the 140 degrees F temperature limit for the intended service condition.
