Parker 8MSC12N-B Compression X Mnpt Brass Connector

Product Description

The PARKER 8MSC12N-B is a brass compression tube connector designed to join compression tubing to a male NPT threaded port. It provides a reliable, leak-resistant mechanical connection rated for working pressures up to 2200 psi, making it suitable for demanding fluid and gas line applications. The fitting is constructed from brass, offering good corrosion resistance across a wide range of media. Licensed plumbers, HVAC technicians, and industrial pipefitters typically install this connector wherever a compression-to-male-NPT transition is required in a pressurized system.

This connector is used in residential and commercial plumbing, HVAC refrigerant or fluid lines, instrumentation tubing, and light industrial fluid systems. Its compression-by-MNPT end configuration makes it a practical choice when connecting soft copper or compatible tubing to threaded equipment ports, manifolds, or valves. The 3/4 inch thread size accommodates standard NPT fittings commonly found in trade plumbing and mechanical systems.

Key Features

• Brass construction provides corrosion resistance for a wide range of fluid and gas media
• Rated to 2200 psi maximum working pressure for demanding pressurized applications
• 3/4 inch MNPT thread conforms to MPT thread standard for standard plumbing connections
• Compression x MNPT end configuration enables direct tube-to-thread transitions without additional adapters
• Single-piece unit ships individually, suitable for retrofit or repair work

Compatibility

Designed as an OEM-style compression fitting for use in pressurized fluid and gas tubing systems requiring a compression-to-male-NPT transition at 3/4 inch thread size.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and isolate the system completely before removing or installing any fitting. Hand-tighten the compression nut onto the fitting body, then tighten with a wrench per standard trade practice — do not overtighten, as brass fittings are subject to thread damage. Verify system pressure does not exceed the 2200 psi working pressure rating after installation and before returning the system to service.
