Parker 6-6 Hbz-b Brass Compression Tube Union 2300 Psi

Product Description

The PARKER 6-6 HBZ-B is a brass compression tube union designed to join two compression-end tubing runs in a single inline connection. It creates a leak-resistant, pressure-rated seal without soldering or threading, making it a practical choice for instrumentation lines, fuel supply runs, refrigeration tubing, and general hydraulic or pneumatic plumbing. Rated to 2300 psi maximum working pressure and manufactured from brass conforming to ASME-SB75 and ASTM-B75 standards, this fitting delivers consistent material quality and dimensional accuracy. HVAC technicians, plumbers, and instrumentation mechanics regularly specify this type of union for quick, reliable field joints on copper or compatible soft-metal tubing.

This union is suited for residential and light commercial installations where compression fittings are the specified or preferred connection method. Typical applications include refrigerant-side copper tubing repairs, water supply line connections, pneumatic control tubing, and fuel gas instrument lines where compression fittings are code-permitted. Its brass construction resists corrosion in humid mechanical-room environments and holds up under the thermal cycling common in HVAC and plumbing systems.

Key Features

• 2300 psi maximum working pressure for demanding hydraulic and pneumatic service
• Compression x Compression end connections on both ends — no solder, no threads required
• Brass construction meets ASME-SB75 and ASTM-B75 material standards
• Inline union design allows straight tubing runs to be joined or repaired cleanly
• Compact, lightweight at 0.12 pounds — easy to carry and stage in tight mechanical spaces

Compatibility

Designed as an OEM-style compression tube union for use with compatible copper or soft-metal tubing in compression-fitting plumbing, HVAC, and instrumentation systems. The Swagelok equivalent reference for this fitting is B-600-6.

Installation Notes

This fitting is installed by licensed plumbers, HVAC technicians, or instrumentation mechanics working under applicable local codes. Before installation, shut off and depressurize the line completely. Ensure tubing ends are cut square and deburred to achieve a proper compression seal. Do not overtighten the compression nut — follow the fitting manufacturer's turn-past-finger-tight guidance rather than applying excessive torque, which can damage the ferrule and cause leaks.
