Parker 2FEL4N-316 Compression Female Elbow 1/4-18 Npt Ss

Product Description

The PARKER 2FEL4N-316 is a stainless steel compression tube female elbow designed to connect tubing to female NPT-threaded ports at a 90-degree angle. It features a compression end on one side and a female NPT (FNPT) end on the other, making it suitable for high-pressure and extreme-temperature fluid and gas systems. Rated to 10,900 psi maximum working pressure and a temperature range from -425 degrees F to 1200 degrees F, this fitting is built for demanding process, instrumentation, and industrial applications. Licensed plumbers, pipefitters, and instrumentation technicians typically specify this fitting for critical service lines.

This fitting is used in residential and commercial instrumentation, process control, and high-purity fluid systems where a reliable compression-to-NPT transition is required at a 90-degree change of direction. The 1/4-18 NPT thread size is a common standard in process instrumentation panels, gas sampling lines, and hydraulic or pneumatic control circuits. Its 316 stainless steel construction makes it appropriate for corrosive media, cryogenic service, and high-temperature environments.

Key Features

• 316 stainless steel construction for corrosion resistance and compatibility with aggressive media
• Rated to 10,900 psi maximum working pressure for high-pressure system use
• Wide temperature range from -425 degrees F to 1200 degrees F covers cryogenic through high-heat applications
• Compression x FNPT end connections allow tubing to be joined to female NPT-threaded ports without welding
• 1/4-18 NPT thread standard ensures broad compatibility with common instrumentation fittings
• 90-degree elbow geometry supports directional routing in tight panel or equipment installations

Compatibility

Designed as an OEM-style compression tube fitting for use in instrumentation, process control, and fluid handling systems requiring a 1/4-18 NPT female thread connection with a compression tube inlet.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the system completely before disassembly or installation. Compression fittings require proper tube preparation including clean, square cuts and deburring to achieve a leak-free seal. Consult applicable codes such as ASME B31.3 for process piping or IFGC for gas applications when specifying fitting torque and assembly procedures.
