Parker 4-1 Fbz-ss Compression Tube Connector 1/16 in Ss

Product Description

The PARKER 4-1 FBZ-SS is a stainless steel compression tube connector designed to create a reliable, leak-tight joint between a compression tube end and a male NPT threaded port. Built for high-pressure instrumentation and fluid-handling systems, this fitting handles working pressures up to 10,300 psi, making it well suited for demanding process, hydraulic, and pneumatic applications. At 1.29 inches in overall length and 0.0511 pounds, it is a compact, lightweight component. The 1/16-inch thread size fits small-bore tubing connections. Licensed plumbers, pipefitters, and instrumentation technicians typically install this fitting in industrial and commercial settings.

This connector is used in applications requiring a secure transition from a compression-style tube to a male NPT port. Its stainless steel construction resists corrosion in aggressive media, humid environments, and temperature-cycling conditions. Typical install scenarios include instrument manifolds, pressure sensing lines, gas sampling systems, and chemical process tubing where material compatibility and pressure integrity are critical. The compression-by-MNPT end configuration allows direct connection to NPT-threaded ports on gauges, valves, transducers, and similar components.

Key Features

• Stainless steel body provides corrosion resistance in wet, chemical, and high-cycle environments
• Maximum working pressure rated at 10,300 psi for high-pressure instrumentation service
• Compression x MNPT end connections for tool-free tube insertion with threaded port compatibility
• 1/16-inch thread size suits small-bore instrument tubing applications
• Compact overall length of 1.29 inches minimizes installation footprint
• Lightweight at 0.0511 pounds, reducing load on delicate instrument ports

Compatibility

Designed as an OEM-style compression tube connector for small-bore instrumentation and fluid-handling systems requiring a compression-to-male-NPT transition at 1/16-inch thread size.

Installation Notes

Installation is typically performed by a licensed pipefitter or instrumentation technician. Depressurize and isolate the line fully before disassembly or connection of any compression fitting. Ensure the tube end is cut square, deburred, and fully seated before tightening the compression nut. Follow applicable ASME B31.3 or equivalent process piping codes for pressure-rated joint assembly.
