Smc Pneumatics KQ2L04-08A Reducer Elbow Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2L04-08A is a push-to-connect plug-in reducer elbow fitting designed for pneumatic and fluid tubing systems. It connects two different tube sizes in a 90-degree elbow configuration without tools, using a push-to-connect mechanism for fast, secure assembly. The fitting is constructed from brass and polybutylene and is rated for a maximum working pressure of 145 psi. It suits applications where a quick, reliable tube-to-tube connection is needed at a directional change point. Licensed technicians and pipefitters working on compressed air or low-pressure fluid lines will find this fitting a standard choice for panel-mount and in-line reducer applications.

This fitting is suited for use in industrial automation, pneumatic control panels, compressed air distribution, and light fluid-handling systems. It is commonly installed in settings where tubing must change direction and step down in outside diameter in a single connector. The 4 mm tube outlet and 8 mm stem outside diameter make this fitting appropriate for small-bore pneumatic lines typical in instrumentation and process control work.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure locking
• Reducer elbow configuration combines a 90-degree bend with a tube size reduction in one fitting
• Brass and polybutylene construction provides durability in pneumatic and fluid service
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant for use in environmentally regulated environments

Compatibility

Designed as an OEM-style push-to-connect reducer elbow for pneumatic and fluid tubing systems using 4 mm and 8 mm outside diameter tubing.

Installation Notes

Installation is performed by qualified pipefitters, pneumatic technicians, or instrumentation specialists. Depressurize and lock out the pneumatic or fluid circuit completely before removing or installing any fitting. Ensure tube ends are cut cleanly and squarely with a tube cutter for proper seating and leak-free performance. Follow applicable facility pneumatic safety standards and verify system pressure does not exceed the 145 psi rated maximum after installation.
