Parker 4MBC2N-316 Compression Bulkhead Connector 1/8-27 Npt

Product Description

The PARKER 4MBC2N-316 is a stainless steel compression tube bulkhead connector designed to pass tubing through a panel or bulkhead wall while maintaining a secure, leak-resistant seal. It features a compression fitting on one end and a male NPT thread on the other, allowing connection to standard threaded ports. Rated to 10,300 psi maximum working pressure and a temperature range of -425 degrees F to 1,200 degrees F, this fitting handles demanding process and instrumentation applications. The 316 stainless steel construction provides strong resistance to corrosion and oxidation.

This connector is suited for high-pressure tubing systems in industrial, HVAC, refrigeration, instrumentation, and process piping environments. It is commonly installed where tubing must pass through enclosure walls, control panels, or equipment housings with a clean, pressure-rated feedthrough. The 1/8-27 NPT thread size fits standard small-bore instrument and control line configurations. Licensed plumbers, pipefitters, and instrumentation technicians typically specify this fitting for both new construction and retrofit applications.

Key Features

• Stainless steel 316 construction for corrosion and high-temperature resistance
• Maximum working pressure of 10,300 psi for demanding high-pressure service
• Wide temperature range: -425 degrees F to 1,200 degrees F
• Compression x MNPT end connections for versatile panel feedthrough installations
• 1/8-27 NPT thread size suits small-bore instrumentation and control tubing lines
• Single-piece package suitable for individual repair or low-volume installation work

Compatibility

Designed as an OEM-style compression bulkhead fitting compatible with standard 1/8-27 NPT threaded ports in instrumentation, process control, and high-pressure tubing systems.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician following applicable codes such as ASME B31.3 for process piping. Depressurize and isolate the system fully before removing or installing any compression fitting. Use proper tube preparation tools to ensure a clean, square cut on the tubing end before seating it in the compression ferrule. Do not over-torque the compression nut, as this can deform the ferrule and compromise the seal.
