Parker 6-12 Gbz-ss Compression Tube Connector 3/4 in Ss

Product Description

The PARKER 6-12 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. It uses a compression-style end connection on one side and a female NPT thread on the other, creating a reliable, leak-resistant joint without welding or soldering. Rated to 6,600 psi maximum working pressure, this fitting is suited for high-pressure instrumentation, hydraulic, and pneumatic lines. The 3/4-inch thread size and stainless steel construction make it a durable choice for demanding service environments. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This compression tube connector is used in residential, commercial, and industrial applications where a tubing run must transition to a female NPT-threaded fitting. Common install scenarios include instrument tubing manifolds, process piping, refrigeration tubing connections, and high-pressure fluid lines. The stainless steel body resists corrosion in wet, chemical-exposure, or outdoor environments. It is sold individually and is appropriate wherever a compression-to-FNPT transition fitting is required at the 3/4-inch thread size.

Key Features

• Compression x FNPT end connections for tool-free tubing attachment on one side and threaded port connection on the other
• Maximum working pressure of 6,600 psi for high-pressure service
• Stainless steel construction for corrosion resistance in harsh or wet environments
• 3/4-inch female NPT thread size for wide compatibility with standard NPT-threaded ports
• Single-piece design — sold individually with no minimum order requirement beyond one unit

Compatibility

Designed as an OEM-style replacement or new-installation compression tube connector for systems using 3/4-inch female NPT-threaded ports with compression tubing connections.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or instrumentation technician. Depressurize and isolate the line completely before removing any existing fitting or installing this connector. Apply thread sealant or PTFE tape to the NPT threads in accordance with applicable plumbing or piping codes such as the IPC or ASME B31.3. Do not overtighten the compression ferrule — follow standard compression fitting assembly practice and avoid using pipe wrenches on the compression end of the fitting.
