Parker 10MSC8N-B Compression Tube Connector Brass 2000 Psi

Product Description

The PARKER 10MSC8N-B is a brass compression tube connector designed to join 5/8-inch OD tubing to a 1/2-inch male NPT threaded port. It provides a secure, leak-resistant mechanical connection without soldering or flaring, making it a dependable choice for plumbing, refrigeration, and instrumentation tubing applications. Rated to 2000 psi maximum working pressure, this fitting is built to handle demanding system conditions. Manufactured to ASME-SB75 and ASTM-B75 standards, the brass construction offers good corrosion resistance and durability across a wide range of fluid service applications. Licensed plumbers, HVAC technicians, and instrumentation technicians are the typical installers.

This connector is suited for residential and light commercial applications where copper or compatible tubing must transition to a male NPT threaded connection. Common install scenarios include refrigeration line sets, compressed air systems, water supply lines, and instrumentation tubing runs. The compression end eliminates the need for soldering, which is an advantage in retrofit and service situations where open-flame work is restricted or impractical. The overall length of 1.93 inches keeps the fitting compact in tight spaces.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and depressurize the line fully before connecting or removing any fitting. Hand-tighten the compression nut onto the tube, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass fittings are susceptible to thread and ferrule damage from excessive torque. Verify all connections are leak-free under pressure before returning the system to service, following applicable IPC or IFGC guidelines for the specific fluid service.
