Parker 8-6 Fbz-b Compression X Mnpt Brass Connector

Product Description

The PARKER 8-6 FBZ-B is a straight brass compression tube connector designed to join compression tubing to a male NPT threaded port. With a 3/8 inch thread size and a compression-to-MNPT end configuration, this fitting creates a secure, leak-resistant connection in fluid and gas line applications. Manufactured from brass to ASTM-B-453 and ASTM-B16 standards, it is rated for working pressures up to 2200 psi. Plumbers, HVAC technicians, and pipefitters install this type of fitting where a tube line must terminate at a threaded male connection point without soldering or brazing.

This connector is suited for residential and light commercial applications involving copper or compatible soft metal tubing. Typical install scenarios include refrigerant line connections, instrument tubing, fuel gas distribution, and hydraulic or pneumatic control lines where a reliable metal-to-metal compression seal is required. Its straight body profile keeps the assembly compact in tight spaces. The brass construction resists corrosion in water, oil, and many common process fluids encountered in HVAC, plumbing, and instrumentation work.

Key Features

• Brass construction meets ASTM-B-453 and ASTM-B16 standards for material integrity
• Rated to 2200 psi maximum working pressure
• 3/8 inch compression inlet to male NPT threaded outlet
• Straight fitting shape for in-line tube-to-thread connections
• Overall length of 1.71 inches keeps the assembly low-profile
• Weighs 0.14 pounds for easy single-hand handling during installation

Compatibility

Designed as an OEM-style replacement or direct-use compression fitting for standard compression tube-to-MNPT threaded port connections in plumbing, HVAC, and instrumentation systems. Cross-reference Swagelok part number B-810-1-6 for compatibility verification.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter following applicable IPC or IFGC code requirements. De-pressurize and isolate the line completely before disassembling any existing fitting or installing this connector. Hand-tighten the compression nut onto the tube, then snug with a wrench per standard compression fitting practice — do not over-torque, as brass fittings can crack at the ferrule seat. Apply thread sealant or tape to the MNPT threads as required by the applicable code and fluid service.
