Parker 2MSC2N-B Compression Tube Connector 1/8 Inch Mnpt

Product Description

The PARKER 2MSC2N-B is a brass compression tube connector designed to join tubing to a male NPT threaded port in fluid and gas distribution systems. It uses a compression-style end connection on one side and a 1/8 inch MNPT threaded end on the other, creating a leak-resistant mechanical seal without soldering or welding. Rated to 3600 psi maximum working pressure, this fitting is suited for high-pressure instrumentation, hydraulic, pneumatic, and refrigeration line applications. The brass construction conforms to ASME-SB75 and ASTM-B75 standards. Plumbers, HVAC technicians, and instrumentation technicians install this fitting where tubing transitions to threaded pipe connections.

This connector is used in residential and commercial mechanical systems where copper or compatible soft tubing must terminate at an NPT-threaded valve, manifold, or instrument port. Typical applications include refrigeration systems, compressed air lines, hydraulic control circuits, and instrumentation tubing runs. The 1/8 inch thread size makes it common in low-volume sensing and control line installations. The Swagelok equivalent part number for cross-reference is B-200-1-2.

Compatibility

Cross-references to Swagelok part number B-200-1-2. Designed as an OEM-style replacement or new-install fitting for systems using 1/8 inch MNPT-threaded ports with compression tube connections in brass.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or instrumentation technicians. Depressurize and isolate the system before removing or installing any compression fitting. Apply thread sealant to the MNPT end per applicable codes; do not apply sealant to compression ferrule surfaces. Tighten the compression nut to the manufacturer-specified turns past finger-tight using appropriate wrenches — do not overtighten, as brass ferrules can distort and cause leaks.
