Legris 0104 18 00 Compression Tube Union Brass

Product Description

The LEGRIS 0104 18 00 is a brass compression tube union designed to connect two tube ends within fluid or pneumatic lines. It uses a compression-style fitting that engages both the tube outside diameter and the tube inside diameter, creating a secure, leak-resistant joint without welding or soldering. Rated to a maximum working pressure of 536 psi and a temperature range of -40 degrees F to 250 degrees F, this union suits demanding service conditions in industrial and mechanical systems. Plumbers, pipefitters, and mechanical contractors typically install this fitting where a reliable inline tube connection is required.

This compression tube union is suited for inline connections on 18mm outside diameter tubing in fluid handling, pneumatic, and process piping applications. It is appropriate for both industrial and commercial installations where brass fittings are specified for compatibility with the working medium. The dual-end compression design accommodates tube OD on one side and tube ID on the other, allowing it to bridge tubing segments within the same line run.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or mechanical contractor. Shut off system pressure and depressurize the line completely before removing any existing fittings or installing this union. Ensure tube ends are cut square and deburred before seating into the compression fitting. Follow applicable codes, including ASME B31.1 or B31.3 as appropriate to the system type, and verify the fitting materials are compatible with the working fluid before placing the system back in service.
