Parker 6MBC4N-316 Bulkhead Connector 1/4-18 Npt Ss

Product Description

The PARKER 6MBC4N-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 (MNPT) thread on the other, with a 1/4-18 NPT thread size. Built from 316 stainless steel, it handles working pressures up to 6600 psi and an exceptionally wide temperature range, from -425 degrees F to 1200 degrees F. This fitting is suited for high-pressure instrumentation lines, process tubing, and industrial fluid systems where corrosion resistance and pressure integrity are critical.

This bulkhead connector is used in applications requiring tubing to pass through enclosure walls, panels, or manifolds in industrial, HVAC, and process control environments. It is well suited for hydraulic lines, pneumatic systems, and instrumentation tubing runs where a through-panel connection must maintain pressure integrity. Licensed plumbers, pipefitters, and instrumentation technicians typically install this fitting in commercial and industrial service scenarios.

Key Features

• Stainless steel (316) construction for corrosion resistance in aggressive environments
• Maximum working pressure of 6600 psi for high-pressure system compatibility
• Temperature range of -425 degrees F to 1200 degrees F for extreme service conditions
• Compression x MNPT end connections for versatile tubing-to-pipe hookups
• 1/4-18 NPT thread standard for compatibility with standard pipe fittings
• Bulkhead design allows secure through-panel tubing installation

Compatibility

Designed as an OEM-style compression bulkhead fitting for use in high-pressure tubing systems requiring a through-panel connection with a 1/4-18 NPT thread and compression tube end.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician following applicable codes such as ASME B31.3 for process piping. Depressurize and isolate the line completely before removing or installing any fitting. Use appropriate thread sealant on the NPT male thread and tighten the compression nut to the fitting body per standard compression fitting practice without over-tightening. Verify system pressure and inspect for leaks before returning to service.
