Cerrobrass 64A-886 Compression Tube Union Brass

Product Description

The CERROBRASS 64A-886 is a brass compression tube union designed to join three compression tube connections in a single fitting. It connects tubing with outside diameters of 1/2 inch, 1/2 inch, and 3/8 inch using compression-style end connections on all three ports. The brass construction provides corrosion resistance suitable for potable water, fuel gas, and refrigeration tubing applications. This fitting is a standard stocking item used by plumbers, HVAC technicians, and refrigeration mechanics in both residential and light commercial work.

This union fitting is suited for applications where a branch or transition connection is needed between three compression-end tube runs. Typical use cases include copper tubing systems for water supply, refrigerant lines, and fuel distribution where a leak-tight mechanical connection is required without soldering or flaring. The mixed-diameter ports allow a 3/8-inch tube run to tie into a 1/2-inch main line in the same fitting body.

Key Features

• Brass body construction for durability and corrosion resistance
• Three compression-style end connections for tool-accessible, solder-free installation
• Mixed port sizing: two 1/2-inch OD ports and one 3/8-inch OD port
• Meets SAE standards and carries Proposition 65 compliance notation
• Compact single-body fitting reduces connection points in multi-tube assemblies

Compatibility

Designed as an OEM-style replacement and standard-use compression union for copper and compatible soft tubing systems requiring 1/2 x 1/2 x 3/8-inch OD compression connections.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians. Shut off the water supply or isolate the refrigerant circuit before beginning work. Compression fittings require only standard wrenches; do not overtighten, as this can crack the ferrule or distort the tubing end. Verify tubing is cut square and deburred before seating the ferrule to ensure a leak-free seal.
