Parker 5-4 Fbz-ss Compression X Mnpt Connector 1/4 in Ss

Product Description

The PARKER 5-4 FBZ-SS is a stainless steel compression tube connector designed to join tubing to a male NPT threaded port in fluid and gas distribution systems. It accepts a 1/4 inch thread and features a compression-to-MNPT end connection configuration, making it a reliable choice for secure, leak-resistant tube terminations. Rated for a maximum working pressure of 8100 psi, this connector is built for demanding service environments. Licensed plumbers, pipefitters, and HVAC technicians typically install this fitting during new construction, retrofits, or maintenance on high-pressure tubing runs.

This fitting suits applications in industrial fluid lines, refrigeration systems, instrumentation tubing, and hydraulic circuits where a stainless steel compression-to-male NPT transition is required. The corrosion-resistant construction makes it appropriate for use in wet, chemically active, or outdoor environments. It ships individually and is intended for single-point installation in systems requiring a dependable, high-pressure tube-to-pipe connection.

Key Features

• Stainless steel construction resists corrosion in harsh service environments
• Compression x MNPT end connections allow tubing to thread directly into a female NPT port
• Maximum working pressure of 8100 psi suits high-pressure fluid and gas service
• 1/4 inch thread size with MPT thread standard for consistent fitment
• Overall length of 1.52 inches for compact installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation compression-to-MNPT fitting for systems requiring a 1/4 inch MPT thread connection with compression tube entry.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician familiar with compression fittings and NPT thread standards. Depressurize and isolate the system completely before disassembling or installing any fittings. Use appropriate thread sealant on the MNPT threads as required by the applicable system and code standards. Do not overtighten compression nuts, as this can deform the ferrule and compromise the seal.
