Parker 6-4 Gbz-ss Compression Tube Connector 1/4 in Ss

Product Description

The PARKER 6-4 GBZ-SS is a stainless steel compression tube connector designed for high-pressure fluid and gas line applications. It provides a leak-tight mechanical joint between a compression tube end and a female NPT threaded port, rated to a maximum working pressure of 6,600 psi. The stainless steel body resists corrosion and handles demanding service environments including hydraulic, pneumatic, refrigeration, and instrumentation systems. Licensed plumbers, pipefitters, and HVAC technicians typically specify this fitting where stainless material and high-pressure ratings are required.

This connector is suited for both residential and commercial installations where a 1/4 inch compression tube must transition to a 1/4 inch female NPT port. Common applications include instrument tubing connections, process control lines, refrigerant service ports, and compressed gas distribution panels. The compression-to-FNPT configuration makes it a practical solution for connecting flexible or rigid tubing to threaded manifolds, valves, or equipment ports without welding or soldering.

Key Features

• Stainless steel construction for superior corrosion resistance in harsh or wet environments
• Maximum working pressure of 6,600 psi suits high-pressure hydraulic, pneumatic, and instrumentation applications
• Compression x FNPT end connections allow tube-to-threaded-port transition without soldering
• 1/4 inch thread size with FPT thread standard for broad compatibility with standard NPT fittings
• Compact single-piece connector keeps installation straightforward and minimizes potential leak points

Compatibility

Designed as an OEM-style replacement or service fitting for systems requiring a 1/4 inch compression-to-FNPT stainless steel connector rated for high-pressure service.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes such as the IPC or IFGC. Depressurize and isolate the line completely before removing or installing any compression fitting. Use appropriate tube preparation tools to ensure a clean, square tube cut for a proper compression seal. Do not over-tighten the compression nut, as this can deform the ferrule and compromise the seal.
