Smc Pneumatics KQ2L07-09A Reducer Elbow Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2L07-09A is a push-to-connect plug-in reducer elbow tube fitting designed for pneumatic and fluid transfer systems. It accepts tubing with a 0.25-inch outside diameter and features a 5/16-inch stem outside diameter, allowing it to connect lines of differing sizes in a compact elbow configuration. Built from brass and polybutylene, this fitting handles a maximum working pressure of 145 psi across a service temperature range of 23 degrees F to 140 degrees F. Installation requires no tools for tube insertion, making it well suited for fast assembly and field repairs. Licensed pneumatic technicians and mechanical contractors are the typical installers.

This reducer elbow fitting is used in compressed air distribution, pneumatic control circuits, and general fluid transfer lines where a directional change and size transition are needed at the same connection point. Its push-to-connect design allows quick tube insertion and secure locking without ferrules or thread sealant on the tube side. It is appropriate for both light industrial and commercial pneumatic systems operating within its rated pressure and temperature limits.

Key Features

• Push-to-connect design enables tool-free tube insertion and quick assembly
• Reducer elbow configuration handles both a 90-degree direction change and a tube size transition in one fitting
• Brass and polybutylene construction provides durability across a broad service range
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F suits most indoor pneumatic environments
• RoHS compliant materials

Compatibility

Designed as an OEM-style push-to-connect reducer elbow replacement for pneumatic tubing systems using 0.25-inch outside diameter tubing with a 5/16-inch stem connection.

Installation Notes

Installation is performed by licensed pneumatic technicians or mechanical contractors. Depressurize and lock out the pneumatic system before removing or installing any fitting. Ensure tubing ends are cut cleanly and squarely with a tube cutter to achieve a proper push-to-connect seal. Verify that tubing outside diameter and system pressure do not exceed the fitting ratings before returning the system to service.
