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

Product Description

The PARKER 12-12 GBZ-SS is a compression tube connector designed to create a secure, leak-resistant joint between a compression tube end and a female NPT threaded port. Built from stainless steel, this fitting handles a maximum working pressure of 5800 psi, making it well suited for demanding fluid and gas line applications. The connector accepts tubing with a 3/4 inch outside diameter and threads into standard NPT female ports. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in high-pressure instrumentation, hydraulic, and process piping systems.

This fitting is appropriate for use in both commercial and industrial environments where stainless steel construction is required for corrosion resistance or cleanliness standards. Typical applications include instrument tubing connections, process control lines, and fluid handling systems where a compression-to-FNPT transition is needed. The NPT thread standard ensures broad compatibility with standard pipe fittings and valves found across industrial, HVAC, and plumbing installations.

Key Features

• Stainless steel construction for corrosion resistance in harsh or wet environments
• Maximum working pressure of 5800 psi for high-pressure system use
• Accepts 3/4 inch outside diameter tubing on the compression end
• Female NPT (FNPT) threaded port on opposing end for standard pipe connections
• Compression fitting design eliminates the need for soldering or welding at installation

Compatibility

Designed as a compression-to-FNPT connector for standard NPT threaded ports in industrial, plumbing, and instrumentation systems accepting 3/4 inch OD tubing.

Installation Notes

Installation of compression fittings is typically performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC. Shut off and fully depressurize the system before disassembly or installation. Hand-tighten the compression nut first, then advance with a wrench — do not overtighten, as excessive force can deform the ferrule and compromise the seal. Apply appropriate thread sealant or PTFE tape to the NPT threads per local code requirements.
