Parker 3MSC2N-316 Compression Tube Connector 1/8-27 Npt

Product Description

The PARKER 3MSC2N-316 is a stainless steel compression tube connector designed to join compression tubing to a male NPT threaded port. It transitions a compression fitting end to a 1/8-27 NPT male thread, making it a standard choice for instrument lines, process tubing, and fluid system assemblies. Rated to 10,300 psi maximum working pressure and suitable for service from -425 degrees F to 1,200 degrees F, this fitting handles demanding temperature and pressure conditions. Licensed plumbers, pipefitters, and instrumentation technicians install this type of connector in gas, liquid, and hydraulic line applications where a leak-tight mechanical grip on the tube is required without soldering or welding.

This connector is appropriate for residential and commercial instrumentation, process control, HVAC refrigerant sensing lines, and industrial fluid systems where a compression-to-NPT transition is needed. Its stainless steel construction makes it well suited for corrosive environments, high-purity fluid service, and outdoor or marine installations where carbon steel fittings would be unsuitable. The 1/8-27 NPT thread is one of the most common small-bore thread sizes found on gauges, sensors, valves, and manifold blocks across a wide range of system types.

Key Features

• Stainless steel body for corrosion resistance and long service life
• Compression x MNPT end connections allow tubing to thread-port transitions without soldering
• Rated to 10,300 psi maximum working pressure for high-pressure instrumentation service
• Extended temperature range of -425 degrees F to 1,200 degrees F covers cryogenic through high-heat applications
• 1/8-27 NPT thread standard for broad compatibility with gauges, sensors, and valves
• Overall length of 1.23 inches for compact installation in tight spaces

Compatibility

Designed as an OEM-style compression tube connector for instrumentation and fluid system tubing lines using 1/8-27 NPT threaded ports in compression fitting applications.

Installation Notes

Installation is typically performed by a licensed pipefitter, plumber, or instrumentation technician. Depressurize and isolate the line before removing or installing any compression fitting. Hand-tighten the compression nut onto the tube, then apply the manufacturer-recommended number of additional turns with a wrench to seat the ferrule without overtightening. Apply thread sealant appropriate for the service fluid to the NPT threads per IFGC or applicable code requirements before making up the threaded connection.
