Parker 394PDSS-6-6 Bulkhead Coupler 316 Ss 150 Psi

Product Description

The PARKER 394PDSS-6-6 is a double end shutoff bulkhead coupler with compression fittings on both ends, constructed from 316 stainless steel. Designed to pass tubing through a panel or bulkhead while providing shutoff capability at both ends, this coupler isolates flow during disconnection without requiring a separate valve. The compression-by-compression end connections allow for tool-assisted tube installation without brazing or threading. Rated to a maximum working pressure of 150 psi, this fitting suits instrumentation, fluid transfer, and process piping applications where stainless corrosion resistance and inline shutoff are required. It is typically installed by plumbers, pipefitters, or instrumentation technicians.

The 394PDSS-6-6 is suited for panel-mount installations in industrial, commercial, and process environments where tubing must pass through a bulkhead and shutoff capability at both sides of the panel is necessary. The 316 stainless steel body provides resistance to corrosive media and is appropriate for use in chemical, marine, and sanitary adjacent applications. The double end shutoff design allows either side to be disconnected without releasing system pressure, supporting maintenance procedures without full system shutdown.

Key Features

• Double end shutoff design allows disconnection at either end without full flow release
• 316 stainless steel body offers corrosion resistance for harsh and wet environments
• Compression-by-compression end connections for tool-assisted, no-braze tube installation
• Rated to 150 psi maximum working pressure
• Bulkhead configuration mounts through panels to route tubing between enclosures or compartments

Compatibility

Designed as an OEM-style replacement or direct-install fitting for compression tube systems requiring bulkhead panel routing with double end shutoff capability in 316 stainless steel construction.

Installation Notes

Installation is typically performed by licensed plumbers or instrumentation technicians familiar with compression fitting assembly. Depressurize and isolate the tubing circuit fully before installing or removing this fitting. Compression fittings require proper ferrule seating and consistent torque applied with a backup wrench to avoid distorting the fitting body or bulkhead nut. Follow applicable plumbing and process piping codes for the jurisdiction and system type.
