Aignep Usa 88040-02 Union Tube Fitting 1/8 Inch Od

Product Description

The AIGNEP USA 88040-02 is a push-to-connect union tube fitting designed to join two tubes of equal outside diameter in a straight-line configuration. Constructed from nickel-plated brass, this union accepts 1/8-inch OD tubing and holds a maximum working pressure of 250 psi. The push-to-connect design allows for fast, tool-free insertion and secure locking without ferrules or compression nuts. Buna O-rings provide the internal seal. At 1.024 inches overall length and 0.05 pounds, this fitting is compact enough for tight panel or cabinet installations. It is suited for use in pneumatic control lines, instrumentation tubing, and light fluid distribution systems.

This fitting is appropriate for residential and light commercial applications where small-diameter pneumatic or fluid tubing must be joined quickly and reliably. Typical installation scenarios include pneumatic control panels, HVAC instrumentation lines, and compressed-air distribution networks operating within the rated pressure and temperature envelope. The union style makes it equally useful for mid-run connections and for serviceability, since the fitting releases tubing without cutting when the collet is depressed.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• Nickel-plated brass body resists corrosion in pneumatic and light fluid service
• Rated to 250 psi maximum working pressure
• Operating temperature range: -4 degrees F to 160 degrees F
• Buna O-ring internal seal for reliable, low-leak performance
• Compliant with REACH, RoHS, ISO 14743:2004, and PED 2014/68/UE standards

Compatibility

Designed for use with 1/8-inch OD tubing in tube-to-tube union configurations on pneumatic and light fluid systems operating within the rated pressure and temperature limits of this fitting.

Installation Notes

This fitting is typically installed by pneumatic system technicians, HVAC controls technicians, or instrumentation trades. Before servicing any line, depressurize and isolate the system completely. Ensure tubing ends are cut square and free of burrs before insertion to guarantee a proper seal at the collet. Verify the system operating pressure and temperature do not exceed the rated limits of this fitting.
