Parker 8-8 Hbz-b Brass Compression Tube Union 2200 Psi

Product Description

The PARKER 8-8 HBZ-B is a brass compression tube union designed to join two compression-end tubing runs into a single continuous line. The fitting uses compression connections on both ends, eliminating the need for soldering or threading in many retrofit and new-install scenarios. Rated to 2200 psi maximum working pressure, it meets ASME-SB75 and ASTM-B75 brass material standards. Licensed plumbers, HVAC technicians, and refrigeration mechanics install this type of union in refrigerant piping, pneumatic lines, instrument tubing, and general fluid service applications where a reliable, pressure-rated inline connection is required.

This union is suited for residential and commercial applications where copper or compatible tubing must be joined mid-run without a flame or threading equipment. Typical install scenarios include instrument and control lines, pneumatic signal tubing, and low-to-medium pressure fluid systems. The 2200 psi working pressure rating makes it appropriate for a broad range of compressed-gas and liquid service conditions encountered in mechanical and process piping.

Key Features

• Compression x compression end connections on both sides for tool-only assembly
• Brass body construction conforming to ASME-SB75 and ASTM-B75 standards
• 2200 psi maximum working pressure rating
• Union configuration allows disconnection and reconnection of the tubing run without cutting
• Lightweight at 0.2 pounds, suitable for space-constrained installations

Compatibility

Designed as an OEM-style compression union for use with copper or compatible tubing in compression-fitting systems rated at or below 2200 psi. Cross-referenced to Swagelok part number B-810-6.

Installation Notes

Installation is performed by licensed plumbers or qualified mechanical technicians. Always depressurize and isolate the tubing line before disassembly or connection. Ensure tubing ends are cut square, deburred, and fully seated into the fitting body before tightening the compression nut. Follow applicable plumbing codes and the fitting manufacturer torque guidance for compression fittings to avoid over-tightening, which can crack the ferrule or distort the tube end.
