Parker 12FSC12N-316 Compression Tube Connector 3/4-14 Npt

Product Description

The PARKER 12FSC12N-316 is a stainless steel compression tube connector designed to join tubing to female NPT threaded ports in high-pressure and extreme-temperature fluid or gas systems. It features a compression end on one side and a female NPT (FNPT) thread on the other, providing a reliable mechanical seal without welding or brazing. Rated to 5800 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1200 degrees F, this fitting is suited for demanding instrumentation, process, and industrial piping applications. Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians working with tubing systems that require leak-tight mechanical connections.

This connector is commonly used in process instrumentation, hydraulic lines, pneumatic systems, and industrial fluid handling installations where stainless steel construction is required for corrosion resistance or compatibility with aggressive media. The 3/4-14 NPT thread size and compression end configuration make it a standard choice for connecting tubing runs to valves, gauges, manifolds, or panel-mounted ports in both commercial and industrial environments.

Key Features

• Stainless steel body for corrosion resistance in harsh and aggressive media environments
• Maximum working pressure of 5800 psi for high-pressure system compatibility
• Wide temperature range from -425 degrees F to 1200 degrees F
• Compression x FNPT end connections eliminate the need for welding or brazing at the tubing end
• 3/4-14 NPT thread standard ensures compatibility with standard female NPT ports

Compatibility

Designed as an OEM-style compression fitting for industrial and instrumentation tubing systems requiring a 3/4-14 NPT female threaded port connection with a compression tube end.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician following applicable codes such as ASME B31.1 or B31.3 for process piping. Isolate and depressurize the system fully before removing or installing any fittings. Ensure the tubing end is cut cleanly and deburred before seating it into the compression end, and tighten the compression nut to the fitting body per standard compression fitting practice without over-torquing. Inspect for leaks after restoring system pressure.
