Parker 392P-6-6 Brass Bulkhead Coupler Body Tube Plug-in

Product Description

The PARKER 392P-6-6 is a brass compression tube bulkhead coupler body designed to connect a compression tube end to a plug-in stem end through a panel or bulkhead wall. This fitting is used in fluid and pneumatic line routing where tubing must pass through a partition or enclosure wall and maintain a secure, leak-resistant connection on both sides. The body is constructed from brass, rated for a maximum working pressure of 150 psi and a temperature range of 0 degrees F to 150 degrees F. HVAC technicians, plumbers, and fluid system installers work with this style of fitting in control line and instrument tubing applications.

This bulkhead coupler body is suited for residential and light commercial applications where compression tube lines must be routed through panels, enclosures, or equipment frames. The tube-to-plug-in stem configuration allows one side to accept a compression tube connection while the other accepts a plug-in stem, making it practical for mixed-connection plumbing and instrumentation setups. It is sold individually and is a direct-fit component in compressed air, refrigerant control, and hydraulic instrument line assemblies where panel penetration fittings are required.

• Operating temperature range of 0 degrees F to 150 degrees F
• Sold as a single unit with no minimum order beyond one piece

Compatibility

Designed as an OEM-style replacement or new-installation component for compression tube bulkhead fitting applications in fluid handling, pneumatic control, and instrument tubing systems.

Installation Notes

Installation of bulkhead fittings is typically performed by licensed plumbers, HVAC technicians, or instrument technicians. Depressurize and isolate the fluid or pneumatic line completely before removing or installing any fitting. Ensure the panel or bulkhead material is compatible with the mounting hardware and that the opening diameter matches the fitting body before tightening the locknut. Follow applicable codes including IPC or IFGC as relevant to the system being serviced.
