Parker 2-2 GH2BZ-B Bulkhead Female Connector 1/8 Inch

Product Description

The PARKER 2-2 GH2BZ-B is a compression tube bulkhead female connector designed to create a secure, leak-free pass-through in panels, bulkheads, or enclosure walls. Constructed from brass meeting ASME-SB75 and ASTM-B75 standards, this fitting connects a compression tube end on one side to a 1/8 inch female NPT thread on the other. It is rated to a maximum working pressure of 3600 psi, making it well-suited for high-pressure fluid and gas lines found in HVAC, refrigeration, pneumatic, and instrumentation systems. Licensed plumbers, HVAC technicians, and instrumentation mechanics install this fitting where tubing must pass through a structural wall or panel.

This fitting is used in residential and commercial applications where copper or compatible tubing must be routed through a bulkhead without compromising system pressure integrity. Typical install scenarios include equipment panels, control enclosures, and manifold assemblies. The compression-by-FNPT configuration allows direct connection to female NPT-ported equipment or fittings on one end while gripping the tube mechanically on the other, eliminating the need for soldering or flaring at the bulkhead point.

Key Features

• Bulkhead configuration allows tube pass-through in panels and enclosure walls
• Compression x FNPT end connections for tool-assisted, solder-free installation
• Brass construction per ASME-SB75 and ASTM-B75 for corrosion resistance
• Maximum working pressure of 3600 psi for high-pressure system compatibility
• 1/8 inch female NPT thread on the pipe end
• Overall length of 1.76 inches for compact panel mounting

Compatibility

Designed as an OEM-style compression bulkhead fitting for use with compatible small-diameter tubing in high-pressure fluid and gas systems. Cross-reference Swagelok part number B-200-71-2 for equivalency verification.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic. Depressurize and isolate the system completely before removing or installing any compression fittings. Follow applicable codes including ASME B31 piping standards when selecting this fitting for pressure system use. Do not overtighten the compression nut, as excess torque can deform the ferrule and compromise the seal.
