Parker 6-6 FH2BZ-SS Bulkhead Connector 3/8 in Ss

Product Description

The PARKER 6-6 FH2BZ-SS is a stainless steel compression tube bulkhead connector designed to pass tubing through a panel, bulkhead, or enclosure wall while maintaining a leak-free seal. The fitting accepts a compression connection on one end and a male NPT thread on the other, allowing a technician to transition between tube and threaded pipe in a single fitting. Rated to 6600 psi maximum working pressure, this connector is built for demanding fluid and gas systems where corrosion resistance and pressure integrity are non-negotiable. Stainless steel construction makes it well-suited for aggressive media, high-moisture environments, and installations where carbon steel fittings would corrode.

This fitting is used in industrial, HVAC, hydraulic, and instrumentation applications where tubing must be routed through a panel or bulkhead without compromising system pressure. The 3/8 inch thread size and compression-by-MNPT end connections make it a practical choice for plumbing technicians and instrumentation specialists working on pneumatic controls, refrigeration piping panels, or process fluid systems. It is sold and installed as a single unit.

Key Features

• Stainless steel construction resists corrosion in wet, chemical, and high-cycle environments
• Maximum working pressure of 6600 psi suits high-pressure fluid and gas applications
• Compression x MNPT end connections allow direct tube-to-threaded-pipe transition at the bulkhead
• 3/8 inch thread size is a common trade size across HVAC, instrumentation, and plumbing systems
• Overall length of 2.265 inches allows installation in standard panel thicknesses without modification
• Single-piece fitting simplifies installation and reduces potential leak points

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube bulkhead applications requiring a 3/8 inch MPT thread standard and compression x MNPT end connections in stainless steel.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician familiar with compression fittings and NPT thread practices. De-pressurize and isolate the system completely before removing or installing any fitting. Apply an appropriate thread sealant to the MNPT threads per the system fluid and applicable codes; do not over-tighten, as stainless steel threads can gall. Verify the compression sleeve is properly seated on the tubing before tightening the compression nut to avoid leaks at the tube interface.
