Parker 12-8 Fbz-b Compression X Mnpt Brass Connector

Product Description

The PARKER 12-8 FBZ-B is a straight brass compression tube connector designed for joining 1/2 inch compression tube ends to male NPT threaded fittings. Built from brass conforming to ASTM-B-453 and ASTM-B16 standards, this connector delivers reliable, leak-resistant connections in fluid and gas distribution systems. It is rated for a maximum working pressure of 1900 psi, making it suitable for demanding service conditions. The overall length is 1.99 inches. Licensed plumbers, HVAC technicians, and pipefitters install this fitting in both new construction and retrofit applications where a compression-to-NPT transition is required.

This connector is used in residential and light commercial plumbing, refrigeration tubing systems, instrumentation lines, and HVAC piping where a compression tube end must mate to a male NPT port. The straight configuration simplifies in-line installations with minimal clearance requirements. It is sold individually and is appropriate for any application demanding a pressure-rated brass transition fitting that meets ASTM material and dimensional standards.

Key Features

• Brass construction conforming to ASTM-B-453 and ASTM-B16 for material and dimensional compliance

• 1/2 inch compression x MNPT end connections for direct tube-to-threaded-port transitions
• Straight fitting shape for clean in-line installation
• Compact overall length of 1.99 inches minimizes space requirements
• Sold individually with no minimum order requirement beyond single-unit purchase

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1/2 inch compression tube systems requiring a male NPT transition. Also referenced under Swagelok part number B-1210-1-8 for cross-reference purposes.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or IFGC guidelines. Shut off system pressure and depressurize the line completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the tube, then apply the manufacturer-recommended additional turns with a wrench — do not overtighten, as this can deform the ferrule and compromise the seal. Inspect the compression sleeve and tube end for burrs or damage before assembly.
