Parker 2-2 GH2BZ-SS Compression Bulkhead Connector 1/8 in

Product Description

The PARKER 2-2 GH2BZ-SS is a compression tube bulkhead female connector designed to route tubing through a panel or bulkhead wall while maintaining a secure, leak-resistant seal. Constructed from stainless steel, this fitting connects a compression tube end to a 1/8 inch female NPT port, allowing fluid or gas lines to pass cleanly from one side of a partition to the other. It is rated for a maximum working pressure of 10,900 psi, making it suitable for high-pressure instrumentation, pneumatic, and hydraulic applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical trade professionals who install this type of fitting.

This bulkhead connector is used in applications where tubing must penetrate a panel, enclosure, or structural wall. Common install scenarios include process instrumentation lines, pneumatic control systems, hydraulic manifolds, and other industrial or commercial fluid-handling assemblies. The compression-by-FNPT end configuration allows direct connection to female pipe-threaded ports on one side and a compression tube on the other, simplifying routing through confined or enclosed spaces. Its stainless steel construction makes it a reliable choice in corrosive or high-purity service environments.

Key Features

• Stainless steel body for corrosion resistance in demanding service environments
• Compression x FNPT end connections for versatile tube-to-pipe-thread routing
• 1/8 inch FPT thread standard for compatibility with standard NPT fittings and ports
• Maximum working pressure rated at 10,900 psi for high-pressure instrumentation and hydraulic use
• Bulkhead design allows tubing to pass cleanly through panels or enclosure walls

Compatibility

Designed as an OEM-style replacement or direct-install compression bulkhead connector for systems using 1/8 inch FNPT ports with compression tube connections in high-pressure instrumentation, pneumatic, or hydraulic service.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified instrumentation technician familiar with compression fittings and NPT thread sealing practices. Depressurize and isolate the system completely before removing or installing any fittings. Apply an appropriate thread sealant to the NPT side per the system fluid compatibility requirements, and tighten compression fittings to manufacturer guidelines without over-tightening, which can damage ferrules. Follow applicable codes including ASME B31.3 for process piping where required.
