Parker 6FSC6N-316 Compression Tube Connector 3/8-18 Npt

Product Description

The PARKER 6FSC6N-316 is a stainless steel compression tube connector designed to join compression tubing to female NPT threaded ports in high-pressure and extreme-temperature fluid or gas systems. With a maximum working pressure of 6600 psi and a temperature range of -425 degrees F to 1200 degrees F, this fitting is built for demanding service environments including instrumentation, process piping, and industrial fluid handling. The 3/8-18 NPT thread size and compression x FNPT end connections make this a straightforward choice for technicians needing a reliable, leak-resistant tube-to-pipe transition. Weighing 0.141 pounds, it is a compact, single-piece fitting suited for tight installations.

This connector is used in applications where tubing must terminate at a female NPT port without welding or soldering. Typical installations include instrument sensing lines, hydraulic control circuits, pneumatic systems, and process fluid lines in both commercial and industrial settings. The 316 stainless steel construction makes it appropriate for corrosive media, offshore environments, cryogenic service, and high-temperature process lines. Licensed plumbers, pipefitters, and instrumentation technicians commonly specify this fitting for code-compliant installations requiring pressure-rated compression connections.

Compatibility

Designed as an OEM-style compression tube connector for use in instrumentation, process, and industrial piping systems requiring a 3/8-18 NPT compression x FNPT connection in 316 stainless steel.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, 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 compression fitting. Ensure tubing is cut square, deburred, and fully seated before tightening the compression nut. Do not over-tighten — follow the fitting manufacturer's recommended turn count from finger-tight to avoid deforming the ferrule or tube.
