Cerrobrass 64A-55 Compression Tube Union 5/16 Inch

Product Description

The CERROBRASS 64A-55 is a brass compression tube union designed to join two lengths of tubing in a straight-line configuration using compression-style end connections on both sides. Built for fluid and gas line service, this fitting accepts 5/16-inch outside diameter tubing and is rated to 400 psi maximum working pressure. The all-brass construction resists corrosion and holds up across a wide service temperature range. Plumbers, HVAC technicians, and refrigeration mechanics use this type of union when a removable, non-soldered connection is required between two tube segments.

This compression union is suited for residential and light commercial plumbing, HVAC refrigerant line work, and fuel or hydraulic tubing applications where an inline union connection is needed. The compression-by-compression configuration allows quick assembly and disassembly without special tools or open flame. Its SAE-rated design makes it appropriate for applications governed by SAE standards in tubing systems handling liquids or gases within its rated pressure and temperature limits.

Installation Notes

This fitting is installed by licensed plumbers or HVAC technicians. Shut off all fluid or gas supply and relieve system pressure before removing or installing any compression fitting. Ensure tubing is cut cleanly and squarely and that ferrules are properly seated before tightening compression nuts. Follow applicable IPC or IFGC guidelines for the specific system type being serviced.
