Parker 4-2 Fbz-ss Compression Tube Connector 1/8 Inch

Product Description

The PARKER 4-2 FBZ-SS is a compression tube connector designed to create a leak-tight junction between a compression tube end and a male NPT threaded port. Constructed from stainless steel, this fitting is built for high-pressure service, rated to a maximum working pressure of 10,300 psi. It measures 1.29 inches in overall length and weighs approximately 0.052 pounds. Plumbers, pipefitters, and instrumentation technicians install this type of fitting in fluid and gas distribution lines where corrosion resistance and pressure integrity are critical requirements.

This connector is suited for instrumentation, hydraulic, pneumatic, and process piping applications in both commercial and industrial environments. The compression-by-MNPT end configuration allows direct connection from a compression tube line into any standard male NPT threaded port or valve body. It is commonly found in control systems, sample lines, and analyzer hookups where stainless steel is specified for compatibility with corrosive media or sanitary requirements.

Key Features

• Stainless steel construction provides corrosion resistance for demanding process and instrumentation service
• Maximum working pressure rated to 10,300 psi for high-pressure system use
• Compression x MNPT end connections allow direct tube-to-threaded-port installation
• 1/8 inch NPT thread size fits standard small-bore instrument valves and manifolds
• Compact overall length of 1.29 inches suits tight-clearance installations

Compatibility

Designed as an OEM-style replacement or new-installation compression connector for small-bore instrumentation and process piping systems using 1/8 inch male NPT ported components.

Installation Notes

Installation should be performed by a qualified pipefitter or instrumentation technician familiar with compression fittings and NPT thread sealing practices. Depressurize and isolate the line completely before removing or installing any fitting. Apply an appropriate thread sealant to the MNPT threads per the system fluid and pressure requirements. Do not overtighten the compression nut, as stainless steel ferrules require controlled make-up to avoid damaging the tube or ferrule seat.
