Parker 8MSC6N-B Compression X Mnpt Tube Connector

Product Description

The PARKER 8MSC6N-B is a straight compression tube connector designed to join copper or compatible tubing to a male NPT threaded port. Constructed from brass meeting ASME-SB75 and ASTM-B75 standards, this fitting provides a secure, leak-resistant connection in fluid and gas distribution systems. It measures 1.71 inches in overall length and carries a maximum working pressure rating of 2200 psi. The Compression x MNPT end configuration allows a tubing run to transition directly into a threaded male fitting seat without soldering or flaring. Licensed plumbers, HVAC technicians, and pipefitters regularly use this type of connector in refrigerant, water, and instrumentation line assemblies.

This connector is suited for residential and light commercial plumbing, HVAC refrigerant piping, and instrumentation systems where a compression-to-NPT transition is required. The 3/8 inch thread size fits common tubing and port configurations found in water supply lines, pneumatic controls, and process instrumentation. It is typically installed where a permanent but serviceable mechanical joint is preferred over soldered or brazed connections.

• 3/8 inch thread size in MPT standard
• Compact overall length of 1.71 inches for tight installation spaces
• Cross-references to Swagelok part number B-810-1-6

Compatibility

Cross-references to Swagelok part number B-810-1-6. Designed as an OEM-style replacement or direct-interchange compression tube connector for 3/8 inch Compression x MNPT applications in plumbing, HVAC, and instrumentation systems.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter following applicable IPC or IFGC guidelines. Shut off and depressurize the system completely before removing or installing any compression fitting. Do not overtighten the compression nut, as excess force can distort the ferrule and compromise the seal. Inspect tubing end for burrs or deformation and ensure a clean, square cut before inserting into the fitting body.
