Parker 6-8 Gbz-b Compression X Fnpt Brass Connector

Product Description

The PARKER 6-8 GBZ-B is a straight brass compression tube connector designed to join tubing to female NPT threaded ports in fluid and gas distribution systems. The fitting accepts a 1/2 inch compression connection on one end and a 1/2 inch FNPT threaded connection on the other, providing a secure, leak-resistant transition between tubing and pipe threads. Constructed from brass to ASTM-B-453 and ASTM-B16 standards, it carries a maximum working pressure of 2300 psi. The overall length is 1.73 inches and the unit weighs 0.21 pounds. Plumbers, HVAC technicians, and industrial pipefitters install this type of fitting in refrigeration, instrumentation, and fluid control applications.

This connector is suited for residential and light commercial systems where tubing must terminate at a threaded female port. Common install scenarios include instrument tubing runs, refrigerant piping accessories, and process fluid lines where a reliable compression-to-pipe-thread transition is required. The straight body geometry keeps the connection inline, minimizing flow restriction. The brass construction resists corrosion in water, refrigerant, and many industrial fluid services.

Designed as an OEM-style replacement or direct-use compression tube connector for systems requiring a 1/2 inch compression to 1/2 inch FNPT straight fitting in brass. Cross-reference Swagelok part number B-600-7-8 for compatibility verification.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter. Shut off and depressurize the system fully before disconnecting or installing any compression fitting. Compression fittings require proper tube preparation — ensure tubing is cut square and deburred before insertion. Follow applicable codes such as the IPC or IFGC for fluid and gas piping installations.
