Parker 8-12 Fbz-b Compression Tube Connector 3/4 in Mnpt

Product Description

The PARKER 8-12 FBZ-B is a straight brass compression tube connector designed to create a leak-tight mechanical connection between a compression tube end and a male NPT threaded port. Built to ASTM-B-453 and ASTM-B16 standards, this fitting handles working pressures up to 2200 psi, making it suitable for demanding fluid and gas distribution systems. The brass construction provides good corrosion resistance across a wide range of media. At 1.99 inches in overall length and weighing 0.29 pounds, it is a compact, single-piece fitting installed by licensed plumbers, pipefitters, and HVAC technicians in both residential and commercial settings.

This connector is used wherever a tube line must terminate or transition into a threaded pipe port. Typical applications include instrument tubing, refrigeration line sets, pneumatic control systems, hydraulic panels, and general fluid distribution manifolds. The compression end grips the tube mechanically without solder or flare tooling, while the 3/4 inch male NPT end threads directly into a female NPT port. It is well-suited for maintenance, repair, and new-installation work in tight spaces where a low-profile straight fitting is required.

• Brass construction meets ASTM-B-453 and ASTM-B16 material standards
• Rated to 2200 psi maximum working pressure for high-pressure service
• Straight fitting shape simplifies inline tube-to-pipe transitions
• Compact overall length of 1.99 inches fits confined installation envelopes
• Cross-references to Swagelok part number B-810-1-12 for sourcing reference

Compatibility

Designed as an OEM-style replacement or direct-fit compression connector for 3/4 inch male NPT threaded ports in fluid, pneumatic, and refrigeration piping systems where compression tube connections are required. Cross-references to Swagelok part number B-810-1-12.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes, including IPC and IFGC where relevant. Depressurize and isolate the line before disassembly or installation. Apply thread sealant to the male NPT threads per the sealant manufacturer and local code requirements. Do not overtighten the compression nut, as excess torque can deform the ferrule and compromise the seal.
