Parker 4-6 Gbz-ss Compression Tube Connector 3/8 in Ss

Product Description

The PARKER 4-6 GBZ-SS is a stainless steel compression tube connector designed to join tubing to female NPT threaded ports in fluid and gas distribution systems. It features a 3/8-inch thread size with a compression-by-FNPT end connection configuration, rated for a maximum working pressure of 10,300 psi. The all-stainless steel construction provides corrosion resistance in demanding service environments. This fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working on high-pressure instrumentation, refrigeration, or process piping applications where a secure, leak-free mechanical connection is required.

This connector is suited for residential and commercial applications where tubing must terminate into a female NPT port. Typical install scenarios include instrument sensing lines, pneumatic control tubing, refrigeration line sets, and chemical or hydraulic service lines where stainless steel material compatibility and high-pressure ratings are necessary. The compression end accepts tubing without soldering or welding, making it practical for field assembly and retrofit work.

Key Features

• Stainless steel body provides corrosion resistance in harsh or wet service environments
• Maximum working pressure of 10,300 psi suitable for high-pressure instrumentation and process lines
• 3/8-inch thread size with FPT thread standard for direct connection to female NPT ports
• Compression x FNPT end connections allow tool-free tubing attachment without soldering or brazing
• Compact connector form factor fits tight inline installations

Compatibility

Designed as an OEM-style replacement or direct-fit compression connector for high-pressure tubing systems requiring a 3/8-inch compression-to-FNPT interface with stainless steel material compatibility.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Depressurize and isolate the system fully before removing or installing any compression fittings. Use appropriate tube preparation tools to ensure a clean, square-cut tube end for a proper compression seal. Do not overtighten the compression nut, as excess force can deform the ferrule and compromise the joint integrity.
