Midland Industries 20600N 4mm Push-to-connect Straight Union

Product Description

The MIDLAND INDUSTRIES 20600N is a metric straight union fitting designed to join two 4 mm push-to-connect lines in a single inline connection. Constructed from nickel-plated brass, this fitting delivers corrosion resistance and durability suited to pneumatic and fluid control systems. It accepts 4 mm tubing on both ends via tool-free push-to-connect installation. The fitting is rated for pressures from 0 to 290 psi and temperatures from -4 to 176 degrees F, making it appropriate for a range of compressed air, instrumentation, and light fluid applications. Plumbers, HVAC technicians, and instrumentation specialists working with metric tubing systems typically install this type of fitting.

This straight union is intended for use in systems that require a secure, leak-resistant inline connection between two runs of 4 mm metric tubing. It is well suited for residential and light commercial applications involving pneumatic control lines, HVAC sensing circuits, and instrumentation tubing where metric push-to-connect fittings are specified. The push-to-connect design eliminates the need for thread sealant or compression tools at the fitting connection points, reducing installation time in tight spaces or panel-mounted assemblies.

Key Features

• Rated 0 to 290 psi working pressure
• Temperature range of -4 to 176 degrees F
• Compact profile at 0.41 inches diameter by 1.19 inches length
• Metric sizing compatible with international and OEM tubing specifications

Compatibility

Designed as a standard inline union for systems using 4 mm outside-diameter metric push-to-connect tubing in pneumatic, instrumentation, or light fluid service applications.

Installation Notes

This fitting is installed by trade professionals working on pneumatic control or instrumentation systems. Before servicing any pressurized line, depressurize the system fully and verify pressure has reached zero before disconnecting existing tubing. Tubing should be cut cleanly and squarely to ensure a proper seal at the push-to-connect collet. Follow all applicable system pressure ratings and do not exceed the 290 psi working pressure limit of this fitting.
