RS PRO Tube-to-Tube Straight Union, Push-In 4 mm to Push-In 4 mm


This RS PRO tube-to-tube straight union connection is made for pneumatic piping applications, such as high pressure oxygen delivery systems. Its push-to-connect one-touch design quickly and securely locks it together.

This straight union connection is perfect for installing in confined spaces because of its six-angle wrench. The body is made from polyoxymethylene (POM) and has a nickel-plated finish to protect it against contamination or rust. Its threads are coated with Teflon to make it easy to join them securely. POM is a good insulator and has excellent resistance against abrasion. The connector's operating temperature ranges from 0°C to +60°C and it has a maximum operating pressure of 10 bar.

The push-on and screw collar design of these fittings makes them secure and suitable for instrumentation, vacuum and general-purpose applications. They can also be used with nylon or polyurethane tubing.
