Parker 8-4 Gbz-ss Compression Tube Connector 1/4 in Ss

Product Description

The PARKER 8-4 GBZ-SS is a stainless steel compression tube connector designed to join tubing to female NPT-threaded ports in fluid and gas distribution systems. With a 1/4-inch thread size and a compression-to-FNPT end configuration, this fitting creates a leak-resistant mechanical connection without welding or soldering. A maximum working pressure rating of 6300 psi makes it suitable for demanding service environments. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting where reliable tube-to-port connections are required in high-pressure or corrosive-environment applications.

This connector is suited for use in hydraulic lines, pneumatic systems, instrumentation tubing, and process piping where stainless steel construction is specified for corrosion resistance. The compression-by-FNPT configuration is a common choice in residential and commercial HVAC, refrigeration, and industrial plumbing installations where tubing meets a threaded female port on a valve, manifold, or component body.

Key Features

• Stainless steel construction for corrosion resistance in harsh or wet environments
• Compression x FNPT end connections eliminate the need for welding or soldering
• 1/4-inch thread size with FPT thread standard
• Rated to 6300 psi maximum working pressure
• Single-piece fitting for straightforward field installation

Compatibility

Designed as an OEM-style replacement or new-installation compression tube connector for 1/4-inch FNPT-ported valves, manifolds, and instrument bodies in plumbing, HVAC, and industrial piping applications.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters. Shut off system pressure and bleed the line before removing or installing any compression fitting. Ensure tubing is cut square and deburred before seating it into the compression body to achieve a proper ferrule seal. Follow applicable IPC or IFGC guidelines for the system type and jurisdiction.
