Parker 5-4 Gbz-ss Compression Tube Connector 1/4 in Ss

Product Description

The PARKER 5-4 GBZ-SS is a stainless steel compression tube connector designed to join tubing to female NPT threaded ports in fluid and gas line systems. It features a 1/4 inch thread size with a compression-to-FNPT end configuration, allowing a secure, leak-resistant mechanical connection without soldering or welding. Rated for a maximum working pressure of 8,100 psi, this fitting is built for demanding service environments where pressure integrity and corrosion resistance are both critical. It is installed by licensed plumbers, HVAC technicians, and industrial pipe fitters working on high-pressure instrumentation, refrigeration, or process lines.

This fitting is suited for residential and commercial applications where stainless steel corrosion resistance is required, such as chemical service lines, compressed gas distribution, HVAC refrigerant-adjacent instrumentation tubing, and hydraulic control circuits. The compression-by-FNPT configuration makes it a common choice when connecting to threaded valve or manifold ports while maintaining a bite-type grip on the tube end. It ships as a single unit and is appropriate for both new installations and field repair work.

Key Features

• Stainless steel construction provides corrosion resistance in wet, chemical, and high-pressure environments
• Compression x FNPT end connections allow tool-assisted, weld-free assembly
• Maximum working pressure rated at 8,100 psi for high-pressure line service
• 1/4 inch FPT thread standard for compatibility with standard NPT-ported components
• Compact single-piece connector format suitable for tight-space installations

Compatibility

Designed as an OEM-style replacement or new-install compression fitting for systems using 1/4 inch FNPT-ported valves, manifolds, or instruments requiring a compression tube connection.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter following applicable IPC or ASME B31 piping codes. Depressurize and isolate the line completely before disassembly or fitting installation. Use appropriate tubing cutters to ensure a clean, square tube end before seating the compression ferrule. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
