Parker 6MSC8N-316 Compression Tube Connector 3/8 Od

Product Description

The PARKER 6MSC8N-316 is a stainless steel compression tube connector designed to create a leak-tight mechanical joint between a 3/8 inch outside diameter tube and a 1/2-14 NPT male threaded port. The compression end grips the tube through ferrule compression, while the MNPT end threads directly into a female NPT fitting or valve body. Rated to 6600 psi maximum working pressure, this connector is built for demanding fluid and gas systems across a wide temperature range, from -425 degrees F to 1200 degrees F. Licensed plumbers, HVAC technicians, and industrial pipefitters install this fitting in high-pressure instrumentation, refrigeration, pneumatic, and process piping applications.

This fitting is suited for both commercial and industrial installations where stainless steel corrosion resistance and high-pressure integrity are required. Typical applications include instrument tubing connections, hydraulic sensing lines, refrigerant piping, and compressed gas systems. The compression-to-MNPT configuration allows a direct transition from tubing to a threaded component without welding or soldering, making it practical for field installations and retrofit work.

Key Features

• 316 stainless steel construction for corrosion resistance in harsh fluid and gas environments
• 6600 psi maximum working pressure rating for high-pressure instrumentation and process lines
• Wide temperature range: -425 degrees F to 1200 degrees F
• Compression x MNPT end connections allow tube-to-threaded-port transitions without welding
• 1/2-14 NPT thread standard for broad compatibility with standard pipe fittings and valves
• Overall length of 1.82 inches for compact inline installation

Compatibility

Designed as an OEM-style compression fitting for use with 3/8 inch outside diameter tubing and 1/2-14 NPT female-threaded ports in industrial, HVAC, refrigeration, and instrumentation piping systems.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician following applicable codes such as ASME B31.3 for process piping or IFGC for gas applications. Shut off and depressurize the system completely before disassembling or installing any compression fitting. Hand-tighten the compression nut first, then advance with a wrench to the manufacturer-recommended turns past finger-tight — do not overtighten, as excessive force can deform the ferrule and compromise the seal. Verify there are no leaks under pressure before returning the system to service.
