Parker 4MSC2N-B Compression Tube Connector 1/8 Mnpt Brass

Product Description

The PARKER 4MSC2N-B is a brass compression tube connector designed to join tubing to a male NPT threaded port in hydraulic, pneumatic, and fluid-handling systems. It provides a leak-resistant mechanical connection using a compression fitting on one end and a 1/8 inch MNPT thread on the other. Rated to 3500 psi maximum working pressure, this fitting is suited for high-pressure instrumentation and control line applications. At 1.29 inches overall length, it is compact enough for tight installations. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This connector is used in residential and commercial settings wherever tubing must terminate at a threaded port, including instrument tubing runs, refrigeration controls, hydraulic circuits, and compressed air distribution systems. The compression-style end accepts standard OD tubing without soldering or flaring, making it practical for retrofit and new-construction installations alike. Conformance to ASME-SB75 and ASTM-B75 standards ensures material quality appropriate for industrial-grade service.

Key Features

• Compression x MNPT end connections for tool-accessible, no-solder tube termination
• 1/8 inch NPT male thread for direct port connection
• 3500 psi maximum working pressure rating
• Brass construction conforming to ASME-SB75 and ASTM-B75 standards
• Compact 1.29 inch overall length suits space-constrained installations
• Sold individually, no minimum order beyond single unit

Compatibility

Designed as an OEM-style replacement and standard compression fitting connector for 1/8 inch MNPT threaded ports in instrumentation, pneumatic, and fluid-handling systems. This fitting carries Swagelok cross-reference part number B-400-1-2 for cross-trade identification.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician following applicable codes such as ASME B31.1 or B31.3 for pressure piping. De-energize or depressurize the system fully before removing or installing any fitting. Apply appropriate thread sealant to the MNPT threads per the system fluid compatibility requirements. Do not overtighten the compression nut — hand-tighten plus the manufacturer-specified number of turns per standard compression fitting practice for the tubing OD in use.
