Parker 8FSC12N-316 Compression Tube Connector 3/4-14 Npt

Product Description

The PARKER 8FSC12N-316 is a stainless steel compression tube connector designed to join tubing to female NPT pipe threads in high-pressure and extreme-temperature fluid systems. It features a compression end on one side and a 3/4-14 FNPT end on the other, providing a reliable, leak-tight mechanical connection without welding or brazing. Rated to 6300 psi maximum working pressure, this fitting handles temperatures from -425 degrees F to 1200 degrees F, making it suitable for cryogenic, steam, and high-pressure gas or liquid service. Plumbers, pipefitters, and instrumentation technicians install this fitting in industrial, commercial, and process piping applications.

This connector is used in systems requiring a transition from compression tubing to female NPT threaded pipe in demanding service environments. Typical applications include hydraulic lines, pneumatic systems, instrumentation tubing, and process fluid lines where temperature extremes and elevated pressures are present. The 316 stainless steel construction makes it well suited for corrosive media, sanitary systems, and outdoor or marine installations where carbon steel fittings would be inadequate.

Key Features

• 6300 psi maximum working pressure for high-pressure service
• Temperature range from -425 degrees F to 1200 degrees F covers cryogenic through high-heat applications
• 316 stainless steel construction resists corrosion and handles aggressive media
• Compression x FNPT end connections allow tubing-to-pipe transitions without welding
• 3/4-14 NPT thread size for standard pipe fitting compatibility
• Weighs 0.30 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or direct-install compression tube connector for systems using 3/4-14 NPT female threaded ports and compatible compression tubing in industrial, commercial, and process piping applications.

Installation Notes

Installation should be performed by a qualified pipefitter or instrumentation technician familiar with compression fittings and NPT threaded connections. Depressurize and isolate the system completely before removing or installing any fitting. Apply thread sealant appropriate for the service media to the NPT threads per the fitting manufacturer and applicable piping code requirements. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
