Parker 6FEL4N-316 Compression Female Elbow 1/4-18 Ss

Product Description

The PARKER 6FEL4N-316 is a stainless steel compression tube female elbow designed to connect a compression tube end to a female NPT port at a 90-degree angle. Constructed from 316 stainless steel, it handles a maximum working pressure of 6600 psi and a temperature range of -425 degrees F to 1200 degrees F, making it suitable for demanding fluid and gas systems. It is installed by licensed plumbers, pipefitters, and instrumentation technicians in high-pressure or corrosive-environment applications where a reliable, leak-free elbow fitting is required.

This fitting is commonly used in industrial, process, and instrumentation piping where stainless steel construction is required for corrosion resistance. The compression-by-FNPT end connections allow a tube line to transition to a female NPT threaded port with no welding required. Typical applications include chemical processing, hydraulic instrumentation lines, and refrigeration or cryogenic systems that demand a wide service temperature range and high-pressure integrity.

Key Features

• 316 stainless steel body provides corrosion resistance in harsh or chemical-laden environments
• Maximum working pressure of 6600 psi suits high-pressure instrumentation and fluid systems
• Wide service temperature range of -425 degrees F to 1200 degrees F supports cryogenic through high-heat applications
• Compression x FNPT end connections allow tube-to-pipe transitions without welding
• 1/4-18 NPT thread size for standard port compatibility

Compatibility

Designed as an OEM-style compression tube female elbow fitting for systems requiring a 1/4-18 NPT female port connection with a compression tube inlet, consistent with standard instrumentation and process piping configurations.

Installation Notes

Installation should be performed by a qualified pipefitter or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the line completely before disassembly or installation. Follow applicable codes such as ASME B31.3 for process piping when making up compression and threaded connections. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
