Parker 4-4 Gbz-ss Compression Tube Connector 1/4 in Ss

Product Description

The PARKER 4-4 GBZ-SS is a stainless steel compression tube connector designed to join tubing to a female NPT threaded port in fluid and gas distribution systems. With a 1/4 inch thread size and a compression-to-FNPT end configuration, this fitting creates a reliable, leak-resistant connection without welding or brazing. It is rated for a maximum working pressure of 10,300 psi, making it suitable for high-pressure instrumentation, hydraulic, and process piping applications. Plumbers, pipefitters, and instrumentation technicians install this type of fitting in commercial and industrial settings where secure, pressure-rated tube connections are required.

This compression connector is used in applications where stainless steel construction is necessary to resist corrosion, high pressure, or elevated temperatures. Typical install scenarios include process instrumentation lines, hydraulic tubing runs, pneumatic control systems, and chemical distribution manifolds. The compression-to-FNPT configuration allows direct connection from a tube end to a female threaded port on valves, gauges, or manifold blocks. It is appropriate for both new installations and replacement work in commercial and industrial environments.

Key Features

• Stainless steel construction resists corrosion in wet, chemical, and high-cycle environments
• Compression x FNPT end connections allow tube-to-threaded-port assembly without welding
• 1/4 inch thread size fits standard instrumentation and process piping ports
• 10,300 psi maximum working pressure rating for high-pressure applications
• Compact, single-piece connector for straightforward inline tube joining

Compatibility

Designed as an OEM-style compression tube connector for 1/4 inch compression-to-FNPT configurations in instrumentation, hydraulic, and process piping systems.

Installation Notes

This fitting should be installed by a licensed plumber, pipefitter, or qualified instrumentation technician. Depressurize and isolate the line completely before disassembling any existing connections. Use appropriately rated tubing and follow applicable codes such as ASME B31.3 for process piping. Do not overtighten the compression nut, as stainless steel fittings are sensitive to galling during assembly.
