Parker 4MSC6N-316 Compression Tube Connector 3/8-18 Npt

Product Description

The PARKER 4MSC6N-316 is a stainless steel compression tube connector designed to join tubing to male NPT pipe threads in high-pressure and extreme-temperature fluid and gas systems. It features a compression end on one side and a male NPT threaded end on the other, making it a direct, leak-resistant transition fitting. Rated to 10,300 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1,200 degrees F, this connector is built for demanding service environments. It weighs approximately 0.10 pounds and measures 1.51 inches in overall length. Plumbers, pipefitters, and instrumentation technicians install this fitting in process, instrumentation, and industrial piping systems.

This connector is suited for residential and commercial applications where a reliable compression-to-NPT transition is required. Typical uses include instrument tubing connections, hydraulic and pneumatic lines, chemical processing piping, and high-pressure gas service. The 3/8-18 NPT thread size is a common standard fitting in instrumentation and industrial fluid handling systems. The 316 stainless steel construction makes it appropriate for corrosive media, cryogenic service, and high-temperature process lines where carbon steel or brass fittings would not perform adequately.

Key Features

• Maximum working pressure of 10,300 psi for high-pressure system service
• Wide temperature range: -425 degrees F to 1,200 degrees F
• 316 stainless steel construction for corrosion and temperature resistance
• Compression x MNPT end connections for tubing-to-pipe-thread transitions
• 3/8-18 NPT thread standard for broad system compatibility
• Compact at 1.51 inches overall length

Compatibility

Designed as an OEM-style compression-to-male-NPT connector for industrial, instrumentation, and process piping systems requiring 3/8-18 NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician. Shut off system pressure and depressurize the line completely before removing or installing any fitting. Use appropriate thread sealant rated for the service media on the NPT threads, and ensure tubing is cut cleanly and deburred before seating in the compression end. Follow applicable ASME, IFGC, or IPC guidelines for the system type and service pressure.
