Smc Pneumatics KQ2L10-12A Reducer Elbow Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2L10-12A is a push-to-connect plug-in reducer elbow tube fitting designed for pneumatic and fluid-line plumbing applications. It transitions between two different tube sizes in a 90-degree elbow configuration, allowing a quick, tool-free connection without ferrules or compression sleeves. The fitting is constructed from brass with a polybutylene insert and is rated for a maximum working pressure of 145 psi. It suits lines operating between 23 degrees F and 140 degrees F, making it a practical choice for both indoor shop-air systems and light industrial pneumatic circuits. Licensed plumbers, pipefitters, and HVAC-R technicians regularly specify this type of fitting for instrument air, process lines, and control tubing runs.

This fitting accommodates a 10 mm outside-diameter tube on one port and a 12 mm outside-diameter tube on the opposite port, enabling a straight size reduction through a 90-degree turn in a single component. It is well suited to residential and light commercial pneumatic panels, compressed-air distribution systems, and control-line assemblies where space is limited and a quick inline reducer elbow is needed. No special tooling is required for installation or tube release, which reduces service time during panel assembly or field repair.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• Reduces and elbows in one body, eliminating an extra fitting and potential leak point
• Brass construction provides corrosion resistance and durability in compressed-air service
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F suits most indoor pneumatic environments
• Accepts 10 mm OD tube on one end and 12 mm OD tube on the other

Compatibility

Designed as an OEM-style push-to-connect reducer elbow for pneumatic tubing systems using 10 mm and 12 mm outside-diameter polyurethane, nylon, or compatible soft tubing in compressed-air and instrument-air applications.

Installation Notes

Installation is performed by pipefitters, plumbers, or qualified pneumatic technicians. Depressurize and lockout the air supply before removing or installing any fitting. Confirm tube ends are cut squarely and deburred before insertion to ensure a full, leak-free seat in the collet. Follow applicable ASME or facility compressed-air codes for system pressure testing after assembly.
