Parker 392PSS-4-4 Bulkhead Coupler Body 316 Ss 150 Psi

Product Description

The PARKER 392PSS-4-4 is a compression tube bulkhead coupler body designed to pass tubing through a panel or bulkhead wall using compression fittings on both ends. Constructed from 316 stainless steel, it delivers strong corrosion resistance in demanding fluid system environments. With a maximum working pressure of 150 psi and an operating temperature range of 0 degrees F to 65 degrees F, this fitting suits moderate-pressure instrumentation and process tubing lines. Licensed plumbers, pipefitters, and instrumentation technicians install this type of fitting where a leak-tight through-panel tube connection is required without welding or threading.

This bulkhead coupler body is suited for residential and light commercial fluid systems, instrumentation panels, hydraulic enclosures, and process equipment where tubing must pass cleanly through a panel wall. Both compression end connections allow for tool-assisted, reliable tube engagement without solder or flare preparation. Applications include HVAC refrigerant and instrument tubing panels, chemical process enclosures, and marine or coastal installations where 316 stainless steel alloy is specified for elevated corrosion resistance.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or marine environments
• Compression x compression end connections on both sides for consistent, repeatable tube sealing
• Rated to 150 psi maximum working pressure
• Operating range from 0 degrees F to 65 degrees F covers typical instrumentation service conditions
• Bulkhead-style body allows through-panel tube routing without additional fittings or adapters

Compatibility

Designed as an OEM-style replacement or new-installation compression bulkhead fitting for instrumentation, process, and fluid system tubing panels where compression x compression end connections are specified.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians. Depressurize and drain the system fully before removing or installing any compression fitting. Use appropriate tube cutters and deburring tools to ensure a clean, square tube end before seating into the compression ferrule. Follow applicable plumbing and instrumentation codes, including ASME B31.1 or B31.3 where required, and verify fitting torque with a calibrated wrench per the system designer's specifications rather than any single product value.
