Parker 4FEL2N-316 Compression Female Elbow 1/8-27 Npt

Product Description

The PARKER 4FEL2N-316 is a stainless steel compression tube female elbow fitting designed to connect a compression tube end to a female NPT threaded port at a 90-degree angle. Rated for a maximum working pressure of 10,300 psi and a temperature range of -425 degrees F to 1200 degrees F, this fitting is built for demanding fluid and gas service in instrumentation, hydraulic, and process piping systems. The 1/8-27 NPT thread size makes it a compact, reliable solution where space is limited and leak-free performance is required. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers for this type of fitting.

This fitting is suited for high-pressure instrumentation lines, pneumatic control circuits, and process tubing connections in both industrial and commercial applications. Its stainless steel construction makes it appropriate for corrosive environments, offshore installations, chemical processing, and food-grade systems where carbon steel fittings are not acceptable. The compression end eliminates the need for welding or flaring on the tube side, while the FNPT end connects directly to threaded ports on valves, manifolds, or instruments.

Key Features

• Maximum working pressure of 10,300 psi for high-pressure service
• Wide temperature range from -425 degrees F to 1200 degrees F
• 316 stainless steel construction for corrosion resistance in harsh environments
• Compression x FNPT end connections eliminate tube flaring on the compression side
• 1/8-27 NPT thread standard for direct connection to standard threaded ports
• Compact female elbow geometry for tight-clearance installations

Compatibility

Designed as an OEM-style replacement or direct-install compression tube female elbow fitting for instrumentation, pneumatic, and high-pressure fluid systems using 1/8-27 NPT threaded ports and compatible compression tube sizes.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or instrumentation technician following applicable codes such as ASME B31.3 for process piping. Depressurize and isolate the system completely before removing or installing any fitting. Apply an appropriate thread sealant to the NPT threads in accordance with the fluid or gas service requirements. Do not overtighten the compression ferrule — follow standard compression fitting assembly practice and confirm the connection is leak-free before returning the system to service.
