Parker 6FEL6N-316 Compression Female Elbow 3/8-18 Npt Ss

Product Description

The PARKER 6FEL6N-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. Built from 316 stainless steel, this fitting handles extreme service conditions, rated to 6,600 psi maximum working pressure and a temperature range of -425 degrees F to 1,200 degrees F. The 3/8-18 NPT thread size on the female end pairs with a compression-style tube connection on the opposite end. Licensed plumbers, pipefitters, and industrial maintenance technicians install this fitting in high-pressure fluid and gas systems where a reliable, leak-free directional change is required.

This fitting is suited for demanding applications in industrial, instrumentation, and process piping systems where stainless steel construction is specified for corrosion resistance or high-temperature service. The compression-by-FNPT configuration makes it a practical choice when transitioning between tubing runs and threaded pipe or equipment ports in tight spaces. It is commonly used in hydraulic, pneumatic, and instrumentation lines operating at elevated pressures.

Key Features

• 316 stainless steel construction provides corrosion resistance in aggressive media and high-temperature environments
• Rated to 6,600 psi maximum working pressure for high-pressure system use
• Wide temperature range from -425 degrees F to 1,200 degrees F suits cryogenic through high-heat applications
• 3/8-18 NPT female thread conforms to standard NPT thread specification
• Compression x FNPT end connections allow transition from tubing to threaded pipe without welding or special tooling

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems using 3/8-18 NPT female threaded connections in industrial, instrumentation, and process piping applications.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber in accordance with applicable piping codes such as ASME B31.3 for process piping. Depressurize and isolate the line completely before disassembling any fittings. Apply appropriate thread sealant to the NPT threads per system media requirements, and ensure the compression sleeve and nut are properly seated before torquing. Do not over-tighten the compression end, as this can deform the ferrule and compromise the seal.
