Parker 6-6 Gbz-ss Compression Tube Connector 3/8 in Ss

Product Description

The PARKER 6-6 GBZ-SS is a stainless steel compression tube connector designed to create a secure, leak-resistant joint between a compression tube end and a female NPT threaded port. Built for high-pressure fluid and gas service, this fitting is rated to a maximum working pressure of 6,600 psi, making it suitable for demanding industrial, HVAC, and mechanical systems. The stainless steel construction resists corrosion and handles elevated temperatures and aggressive media. Plumbers, pipefitters, and HVAC technicians install this type of fitting where a reliable compression-to-female-pipe-thread transition is required without welding or flaring.

This connector is used in applications requiring a 3/8 inch compression tube connection on one end and a 3/8 inch female NPT port on the other. Typical installations include instrumentation lines, pneumatic systems, refrigeration tubing runs, hydraulic control circuits, and process piping where stainless steel is specified for corrosion resistance or cleanliness. It is well suited for both light commercial and industrial environments where high-pressure integrity is a priority.

Key Features

• Maximum working pressure of 6,600 psi for high-pressure service
• Stainless steel construction for corrosion resistance and durability
• 3/8 inch compression x FNPT end connections for reliable tube-to-pipe transitions
• FPT thread standard for compatibility with standard female NPT ports
• Compact connector design suitable for tight installation spaces

Compatibility

Designed as an OEM-style compression-to-female-NPT connector fitting for use in high-pressure fluid and gas piping systems requiring a 3/8 inch compression tube connection and a 3/8 inch female NPT port interface.

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 disassembling any existing fittings or installing this connector. Use the appropriate tube cutting and deburring tools 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.
