Parker 62AB-12 Brass Compression Tube Union 400 Psi

Product Description

The PARKER 62AB-12 is a brass compression tube union designed to join two compression-end tubes in a single straight connection. It provides a leak-resistant, removable joint without soldering or special tooling. Rated to 400 psi maximum working pressure and suitable for service from -65 degrees F to 250 degrees F, it handles a wide range of fluid and gas line applications. The union body is machined brass for corrosion resistance and durability. Plumbers, HVAC technicians, and industrial piping contractors use this fitting wherever a serviceable, pressure-rated tube joint is required.

This compression union is suited for residential and light commercial plumbing, refrigeration lines, pneumatic systems, and instrumentation tubing where a straight union connection is needed. The compression-by-compression end configuration accepts tubing from both sides without any threading or brazing, making it a practical choice for field repairs and new installations. It is packaged as a single unit, allowing individual purchase for repair work or system modifications.

Key Features

Compatibility

Designed as an OEM-style compression tube union for use with standard compression-end tubing in plumbing, HVAC, pneumatic, and instrumentation systems where the pressure and temperature ratings are met.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC and instrumentation technicians. Shut off and depressurize the line before disassembling any existing fitting. Ensure tubing ends are cut square and deburred before seating the compression ferrule. Follow applicable plumbing codes such as the IPC or local jurisdiction requirements for tube union installations in pressurized systems.
