Parker 10MSC12N-316 Compression Tube Connector 3/4-14 Npt

Product Description

The PARKER 10MSC12N-316 is a stainless steel compression tube connector designed to join tubing to male NPT threaded pipe connections in high-pressure and extreme-temperature fluid and gas systems. The fitting transitions from a compression-style tube end to a 3/4-14 MNPT threaded outlet, providing a reliable, leak-resistant seal without welding or flaring. Rated to 6100 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1200 degrees F, this connector is built for demanding industrial, instrumentation, and process applications. It accepts tubing with a 5/8-inch outside diameter and is constructed from 316 stainless steel for corrosion resistance.

This fitting is suited for use in industrial process piping, instrumentation tubing runs, hydraulic and pneumatic systems, and high-purity fluid handling where stainless steel material compatibility is required. The compression-to-MNPT configuration is a common transition point when connecting tubing to threaded valves, manifolds, or equipment ports. It is typically installed by pipefitters, instrumentation technicians, and mechanical contractors working in industrial, chemical, or energy-sector environments.

Key Features

• Stainless steel construction for corrosion resistance in aggressive media and environments
• Rated to 6100 psi maximum working pressure for high-pressure system use
• Wide temperature range from -425 degrees F to 1200 degrees F
• 3/4-14 NPT thread standard for compatibility with standard pipe fittings and equipment ports
• Compression end accepts 5/8-inch OD tubing without welding or flaring
• Compression x MNPT configuration simplifies tube-to-pipe transitions

Compatibility

Designed as an OEM-style compression tube connector for systems requiring a 5/8-inch OD tube compression inlet with a 3/4-14 MNPT threaded outlet in stainless steel construction.

Installation Notes

Installation should be performed by a qualified pipefitter or instrumentation technician following applicable codes and system pressure requirements. Depressurize and isolate the line completely before disassembly or fitting installation. Finger-tighten the compression nut before applying the appropriate number of additional turns with a wrench per the manufacturer compression fitting procedure. Inspect the tubing end for squareness and burrs before assembly to ensure a proper seal.
