Anderson Metals C534706 Brass Compression Tube Union 5/8 in Od

Product Description

The ANDERSON METALS C534706 is a brass compression tube union designed to join two lengths of tubing with matching outside diameters using compression-style end connections. This fitting creates a secure, leak-resistant inline connection without soldering or threading the tubing itself. The union accepts 5/8-inch OD tubing on both ends and uses a 13/16-18 thread for the compression nuts. It is installed by plumbers, HVAC technicians, and refrigeration mechanics in copper or compatible soft-metal tubing systems where a removable, reusable connection point is needed.

This union fitting is suited for residential and light commercial plumbing, HVAC refrigerant lines, and fuel gas or water distribution systems where compression fittings are code-accepted. The compression-by-compression configuration allows field assembly without special tools beyond standard wrenches. Typical applications include joining supply lines, instrument tubing, or soft copper runs where a straight inline union is required. This fitting ships in a package quantity of 2 units per pack.

Compatibility

Designed as an OEM-style replacement or new-installation compression union for systems using 5/8-inch OD tubing with compression-style fittings, consistent with UNSPSC category 27121700 fluid and gas distribution fittings.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians in accordance with applicable IPC or IFGC requirements for compression fittings. Shut off and depressurize the line before disassembly or installation. Hand-tighten the compression nut onto the fitting body, then advance with a wrench - avoid overtightening, which can deform the ferrule and cause leaks. Inspect the ferrule and tubing end for burrs or deformation before reassembly.
