Parker 10MSC6N-316 Compression Tube Connector 3/8-18 Npt

Product Description

The PARKER 10MSC6N-316 is a stainless steel compression tube connector designed to join tubing to threaded pipe connections in high-pressure and extreme-temperature fluid and gas systems. It features a compression end on one side and a male NPT (MNPT) threaded end on the other, allowing a secure, leak-resistant transition between tube and pipe. Rated to 6100 psi maximum working pressure and a temperature range of -425 degrees F to 1200 degrees F, this fitting is built for demanding industrial, instrumentation, and process applications. The 316 stainless steel construction provides strong corrosion resistance across a wide range of media.

This connector is suited for use in instrumentation, process piping, hydraulic, and pneumatic systems where reliable tube-to-pipe transitions are required. The 5/8-inch tube outside diameter and 3/8-18 NPT thread size make it a common choice in commercial and industrial installations where stainless fittings are specified for corrosive environments, cryogenic service, or elevated-temperature process lines. Licensed plumbers, pipefitters, and instrumentation technicians typically install this fitting in industrial plants, refineries, laboratories, and mechanical rooms.

Key Features

• Stainless steel construction for corrosion resistance across aggressive media and extreme temperatures
• Maximum working pressure of 6100 psi for high-pressure system applications
• Wide temperature range from -425 degrees F to 1200 degrees F, suitable for cryogenic and high-heat service
• Compression x MNPT end connections for direct tube-to-pipe transition without welding or brazing
• 3/8-18 NPT thread standard for compatibility with standard pipe threads
• 5/8-inch tube outside diameter compression end

Compatibility

Designed as an OEM-style compression tube connector for instrumentation, process, hydraulic, and pneumatic tubing systems requiring a 5/8-inch OD tube to 3/8-18 NPT male threaded pipe connection in 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 fitting. Hand-tighten the compression nut before applying the appropriate number of turns with a wrench per standard compression fitting practice — do not overtighten, as this can deform the ferrule and compromise the seal. Apply thread sealant rated for the service conditions to the NPT threads before assembly.
