Aignep Usa 88040-53 Union Tube Fitting 5/32 Inch Od

Product Description

The AIGNEP USA 88040-53 is a push-to-connect union tube fitting designed to join two tubes of equal outside diameter in a straight-through configuration. Constructed from nickel-plated brass, it delivers a rated maximum working pressure of 250 psi and handles operating temperatures from -4 degrees F to 160 degrees F. The push-to-connect design allows fast, tool-free tube insertion without ferrules or compression nuts. Overall length is 1.181 inches. This fitting is appropriate for pneumatic control lines, instrumentation tubing, and light fluid transfer systems installed by HVAC technicians, plumbers, and industrial maintenance personnel.

This union fitting is suited for residential and light commercial applications where 5/32 inch OD tubing must be joined inline. Typical scenarios include pneumatic signal lines, control tubing runs, and low-pressure fluid circuits. The Buna O-ring seal material makes it compatible with air and a range of common non-corrosive fluids. Its compact body keeps it manageable in tight panel or equipment enclosures.

Installation Notes

Installation does not require special tools - cut tubing cleanly and squarely before insertion to ensure a proper seal. Verify tubing OD matches the fitting specification before seating. Always depressurize and isolate the line before disconnecting or servicing push-to-connect fittings. Follow applicable system pressure codes and manufacturer guidelines for the equipment being serviced.
