Parker 6FBC4N-316 Bulkhead Female Connector 1/4-18 Npt

Product Description

The PARKER 6FBC4N-316 is a stainless steel compression tube bulkhead female connector designed to pass tubing through a panel or bulkhead while maintaining a secure, leak-free seal. It features a compression inlet on one end and a female NPT (FNPT) thread on the other, allowing direct connection to threaded pipe fittings or instrumentation ports. With a maximum working pressure of 6600 psi and a temperature range from -425 degrees F to 1200 degrees F, this fitting is built for demanding industrial, process, and instrumentation applications. Licensed plumbers, pipefitters, and instrumentation technicians install this type of fitting in high-pressure tubing systems.

This bulkhead connector is suited for panel-mount installations in process control, instrumentation, hydraulic, and pneumatic systems where tubing must pass cleanly through a partition or enclosure wall. The 1/4-18 NPT thread size and compression end connection make it a common choice in industrial plants, refineries, and commercial mechanical systems requiring reliable tube-to-panel transitions. Its stainless steel construction provides corrosion resistance in aggressive media and harsh environments.

Key Features

• Stainless steel body for corrosion resistance in harsh or aggressive-media environments
• Compression x FNPT end connections for tool-assisted, leak-free tube and pipe joining
• Maximum working pressure of 6600 psi for high-pressure instrumentation and process lines
• Wide temperature range from -425 degrees F to 1200 degrees F suitable for cryogenic through high-heat service
• Bulkhead design allows tubing pass-through of panels, enclosures, or equipment walls
• 1/4-18 NPT thread standard ensures compatibility with standard pipe thread connections

Compatibility

Designed as an OEM-style compression bulkhead fitting for industrial and instrumentation tubing systems using 1/4-18 NPT threaded connections with compression tube ends.

Installation Notes

Installation should be performed by a licensed pipefitter or instrumentation technician following applicable process piping codes. Depressurize and isolate the line completely before installing or removing any compression fitting. Use appropriate tube preparation tools to ensure a clean, square tube cut before seating the compression ferrule. Do not over-tighten; follow standard compression fitting make-up procedures to avoid ferrule deformation or thread damage.
