Parker 5FEL4N-316 Compression Female Elbow 1/4-18 Ss

Product Description

The PARKER 5FEL4N-316 is a stainless steel compression tube female elbow fitting designed to connect tubing to female NPT-threaded ports at a 90-degree angle. It features a compression inlet on one end and a 1/4-18 FNPT threaded outlet on the other, providing a secure, leak-resistant joint without the need for soldering or flaring. Rated for a maximum working pressure of 8,100 psi and a temperature range of -425 degrees F to 1,200 degrees F, this fitting is built for demanding industrial and mechanical service applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This fitting is suited for high-pressure fluid and gas line installations in industrial, instrumentation, and process environments. Its stainless steel construction makes it a strong choice for corrosive media, cryogenic service, and high-temperature applications. The compression-by-FNPT configuration is commonly used when transitioning from tubing runs to pipe-threaded equipment, manifolds, or control valves in both residential and commercial mechanical systems.

Key Features

• 316 stainless steel construction for corrosion resistance in harsh and corrosive service environments
• Maximum working pressure of 8,100 psi for high-pressure system compatibility
• Wide temperature range from -425 degrees F to 1,200 degrees F covers cryogenic through high-heat applications
• Compression x FNPT end connections allow tubing-to-pipe transitions without soldering or flaring
• 1/4-18 NPT thread standard for consistent fitment with standard pipe-threaded components

Compatibility

Designed as an OEM-style replacement or direct-install compression tube female elbow for systems requiring 1/4-18 NPT threaded connections with compression tube inlets in stainless steel construction.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly procedures. Before installation, isolate and depressurize the line completely and purge any residual media. Ensure tubing is cut cleanly and squarely and that the compression ferrule is properly seated before tightening the nut. Follow applicable codes such as ASME B31.3 for process piping when determining system design pressure and thread engagement requirements.
