Parker 6-4 Gbz-b Compression Tube Connector 1/4 in Brass

Product Description

The PARKER 6-4 GBZ-B is a brass compression tube connector designed to join tubing to a female NPT threaded port in fluid and gas distribution systems. It provides a secure, leak-resistant mechanical connection using a compression fitting on one end and a female NPT thread on the other. Rated to a maximum working pressure of 2300 psi, this connector is built for demanding service in hydraulic, pneumatic, refrigeration, and instrumentation applications. The brass construction resists corrosion and suits a wide range of compatible media. Licensed plumbers, HVAC technicians, and instrumentation mechanics are the primary installers.

This connector is suited for residential and commercial installations where tubing must transition to a female pipe thread port. Common applications include HVAC refrigerant line connections, compressed air systems, instrumentation tubing, and hydraulic control circuits. The compression-to-FNPT configuration is a standard arrangement for connecting copper, brass, or compatible plastic tubing to valves, manifolds, gauges, and equipment ports with 1/4-inch female NPT inlets.

Key Features

• Compression x FNPT end connections for tubing-to-pipe-thread transitions
• 1/4-inch thread size for compatibility with standard NPT female ports
• 2300 psi maximum working pressure for high-pressure service
• Brass construction for corrosion resistance and durability
• Compact single-piece connector for straightforward installation

Compatibility

Designed as an OEM-style compression tube connector for use in systems requiring a 1/4-inch compression-to-FNPT fitting transition in brass construction.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic familiar with compression fitting procedures. Shut off and depressurize the system completely before disassembling or installing any fittings. Do not overtighten compression fittings; follow the fitting manufacturer's assembly instructions for ferrule seating. Verify that tubing is cut cleanly and deburred before insertion to ensure a proper seal.
