Parker 4MBC4N-316 Bulkhead Connector 1/4-18 Npt Ss

Product Description

The PARKER 4MBC4N-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 inlet connection on one end and a male NPT (MNPT) thread on the other, with a 1/4-18 NPT thread size. Rated for a maximum working pressure of 10,300 psi and a temperature range of -425 degrees F to 1,200 degrees F, this fitting is built for demanding industrial and process applications. The 316 stainless steel construction resists corrosion in aggressive fluid and gas service environments.

This bulkhead connector is suited for instrumentation tubing installations, hydraulic systems, pneumatic lines, and process piping where a tube line must pass through a panel, enclosure, or manifold wall. It is commonly installed in oil and gas, chemical processing, power generation, and high-pressure fluid handling systems. The wide temperature range makes it appropriate for both cryogenic and high-heat service. Plumbers, pipefitters, and instrumentation technicians are the typical trades handling installation of this fitting.

Key Features

• Compression x MNPT end connections for panel pass-through tube installations
• 1/4-18 NPT thread standard for compatibility with standard NPT-threaded ports
• 10,300 psi maximum working pressure for high-pressure service
• Temperature range of -425 degrees F to 1,200 degrees F covers cryogenic through high-heat applications
• 316 stainless steel construction for corrosion resistance in aggressive media
• Overall length of 2.132 inches for compact panel installations

Compatibility

Designed as an OEM-style replacement or direct-fit compression tube bulkhead connector for systems utilizing 1/4-18 NPT threaded ports with compression tube connections.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician familiar with compression fittings and NPT thread standards. Shut off all system pressure and isolate the line before removing or installing any fitting. NPT threads should be sealed with an appropriate thread sealant or PTFE tape rated for the service fluid and pressure. Do not overtighten compression fittings; follow the fitting manufacturer's standard assembly procedure for compression connections.
