Parker 4-8 FH2BZ-SS Bulkhead Connector 0.25 in Ss

Product Description

The PARKER 4-8 FH2BZ-SS is a stainless steel compression tube bulkhead connector designed to route tubing through a panel, wall, or bulkhead while maintaining a secure, leak-resistant seal. It features compression-style tube connection on one end and a male NPT (MNPT) threaded connection on the other, allowing integration into threaded port fittings or manifolds. Rated for a maximum working pressure of 10,300 psi, this fitting is built for high-pressure fluid and instrumentation systems. It accepts tubing with a 0.25 inch outside diameter. Stainless steel construction provides resistance to corrosion and chemical exposure in demanding service environments.

This fitting is commonly used in industrial instrumentation, hydraulic, and high-pressure fluid handling systems where tubing must pass cleanly through a panel or structural member. It is well suited for applications in HVAC controls, refrigeration sensing lines, compressed gas systems, and process piping where a secure, panel-mounted tube transition is required. The compression-to-MNPT configuration supports quick connection to threaded ports without soldering or flaring.

Key Features

• Maximum working pressure of 10,300 psi for high-pressure system compatibility
• Stainless steel construction resists corrosion and chemical attack
• Compression x MNPT end connections for versatile tube-to-thread transitions
• Accepts 0.25 inch outside diameter tubing
• Bulkhead design allows clean panel or wall pass-through routing
• MPT thread standard for broad compatibility with standard threaded ports

Compatibility

Designed as an OEM-style replacement or direct-install compression bulkhead fitting for high-pressure instrumentation and fluid handling systems accepting 0.25 inch OD tubing with MNPT threaded port connections.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or instrumentation technician familiar with high-pressure fitting assemblies. De-pressurize and isolate the system fully before removing or installing any fittings. Ensure tubing is cut cleanly and squarely and is fully seated into the compression body before tightening the nut. Follow applicable codes including ASME B31.3 for process piping or relevant instrumentation standards for the specific application.
