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

Product Description

The PARKER 4FEL4N-316 is a stainless steel compression tube female elbow fitting designed for high-pressure and extreme-temperature fluid and gas line connections. It transitions from a compression tube end to a female NPT threaded port in a 90-degree elbow configuration. Rated to 10,300 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1,200 degrees F, this fitting is built for demanding instrumentation, process, and industrial tubing systems. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers.

This fitting is suited for high-pressure instrumentation lines, pneumatic systems, hydraulic circuits, and process piping where a tube-to-female-pipe transition at a 90-degree angle is required. The 316 stainless steel construction makes it appropriate for corrosive environments, cryogenic service, and high-temperature applications across both commercial and industrial installations. Its 1/4-18 NPT thread size fits standard quarter-inch female pipe ports.

Key Features

• Stainless steel 316 construction for corrosion resistance and durability in harsh environments
• Maximum working pressure of 10,300 psi for high-pressure service
• Wide temperature range from -425 degrees F to 1,200 degrees F covering cryogenic through high-heat applications
• Compression x FNPT end connections for secure, leak-resistant tube-to-pipe transitions
• 1/4-18 NPT thread standard ensures compatibility with common pipe fittings and valves
• 90-degree elbow geometry for routing tubing in tight or angled installations

Compatibility

Designed as an OEM-style compression tube female elbow for instrumentation and process tubing systems requiring a 1/4-inch OD tube compression connection to a 1/4-18 FNPT port.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified instrumentation technician following applicable IPC and process piping codes. Depressurize and isolate the line completely before removing or installing any fitting. Use appropriate thread sealant or PTFE tape on the NPT threads per system requirements, and tighten the compression nut to fitting manufacturer guidelines without overtightening the tube ferrule. Verify system pressure integrity with a leak test before returning the line to service.
