Parker 4-6 FH2BZ-B Bulkhead Connector 3/8 Inch Mnpt Brass

Product Description

The PARKER 4-6 FH2BZ-B is a brass compression tube bulkhead connector designed to route tubing through a panel or bulkhead wall while maintaining a secure, leak-resistant seal. It features a compression inlet connection on one end and a male NPT (MNPT) threaded connection on the other, making it suitable for use in pneumatic, hydraulic, and fluid-transfer systems where a panel pass-through fitting is required. Rated to a maximum working pressure of 3,500 psi, this fitting is built for demanding service environments. The 3/8-inch thread size and brass construction make it a reliable choice for licensed plumbers, HVAC technicians, and pipefitters working with copper or compatible tubing systems.

This bulkhead connector is used in residential and commercial applications where tubing must pass cleanly through an enclosure wall, equipment panel, or mounting surface. Typical installations include refrigeration equipment, compressed air systems, hydraulic control panels, and fluid distribution assemblies. The compression-by-MNPT configuration allows a direct connection to NPT-tapped ports on one side while gripping the tube mechanically on the other side, eliminating the need for soldering or flaring at the bulkhead point.

Key Features

• Compression x MNPT end connections for tool-assisted, no-solder tube termination at the bulkhead
• Maximum working pressure of 3,500 psi for high-pressure pneumatic and hydraulic service
• 3/8-inch thread size with MPT thread standard
• Solid brass construction for corrosion resistance and durability in wet or humid environments
• Compact single-piece body simplifies panel pass-through installations

Compatibility

Designed as an OEM-style replacement or direct-use brass bulkhead connector for systems requiring a compression-to-MNPT panel fitting at 3/8-inch thread size. Cross-reference Swagelok part number B-400-11-6 for procurement equivalency verification.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable mechanical codes. Depressurize and isolate the system completely before removing or installing any compression fitting. Use appropriate wrenches on the hex body to avoid distorting the fitting; do not grip the compression nut threads when torquing. Verify that the tubing is cut square, deburred, and fully seated before tightening the compression nut.
