Smc Pneumatics KQ2L23-04A Reducer Elbow Fitting 145 Psi

Product Description

The SMC PNEUMATICS KQ2L23-04A is a plug-in reducer elbow fitting designed for push-to-connect pneumatic and fluid tubing systems. It reduces tube size at a 90-degree elbow, allowing technicians to change both direction and tube diameter in a single connection point without additional adapters. Constructed from brass and polybutylene, it handles a maximum working pressure of 145 psi and operates across a temperature range of 23 degrees F to 140 degrees F. The push-to-connect design requires no tools for tube insertion, making it a practical choice for assembly and service work on compressed air and low-pressure fluid lines.

This fitting is suited for residential and light commercial pneumatic control systems, compressed air distribution, and low-pressure fluid handling applications. It is commonly installed by HVAC technicians, industrial maintenance professionals, and plumbing tradespeople working with small-bore tubing runs where a direction change and size reduction are needed at the same point. The tube outside diameter is 3.20 mm on the smaller port and the stem outside diameter is 4.00 mm, accommodating the reducer transition in a compact body.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Reduces tube size and changes direction in a single fitting
• Brass and polybutylene construction for corrosion resistance and durability
• Rated to 145 psi maximum working pressure
• Operating temperature range from 23 degrees F to 140 degrees F
• RoHS compliant materials

Compatibility

Designed as an OEM-style replacement or direct-fit component for small-bore push-to-connect pneumatic and low-pressure fluid tubing systems requiring a reducer elbow configuration.

Installation Notes

Installation is performed by qualified pneumatic, HVAC, or plumbing technicians. Always depressurize the system and bleed residual pressure before removing or installing any fitting. Ensure tube ends are cut cleanly and squarely, and that tubing is fully seated in the fitting body until it bottoms out to achieve a proper seal. Verify that the tube outside diameter matches the fitting specification before installation.
