Parker 1-1 Hbz-ss Compression Tube Union 1/16-27 Npt

Product Description

The PARKER 1-1 HBZ-SS is a compression tube union designed to create a leak-tight, all-compression connection between two tube ends without the need for flared or threaded tube ends. Constructed from stainless steel, this union is suited for high-pressure fluid and gas line applications where corrosion resistance and mechanical durability are required. It carries a maximum working pressure of 16,800 psi, making it appropriate for instrumentation, hydraulic, and process tubing systems. The 1/16-27 NPT thread size and 1/16-inch tube outside diameter keep it compact for tight-access installations. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers.

This union is used in residential and commercial instrumentation lines, hydraulic systems, and process piping where small-diameter, high-pressure tube connections are required. The all-compression end connections eliminate the need for soldering or welding, making field assembly and disassembly straightforward. Applications include control line tubing, sample lines, and instrument manifold connections in HVAC, industrial, and laboratory environments.

Key Features

• All-compression end connections on both sides for tool-assisted, no-weld assembly
• Stainless steel construction for corrosion resistance in demanding environments
• Maximum working pressure of 16,800 psi for high-pressure instrumentation and hydraulic service
• 1/16-27 NPT thread size with 1/16-inch tube outside diameter for compact line routing
• Union configuration allows in-line disassembly without disturbing adjacent tubing runs

Compatibility

Designed as an OEM-style replacement and standard compression union fitting for small-diameter stainless steel tubing systems using 1/16-inch outside diameter tube with 1/16-27 NPT thread connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician familiar with high-pressure compression fittings. Depressurize and isolate the line completely before disassembling any existing connection or installing this union. Hand-tighten the compression nut first, then apply the additional turns specified by the fitting manufacturer using appropriate tube fitting wrenches. Verify the connection for leaks before returning the system to service, following applicable IPC or facility-specific pressure-test procedures.
