Parker 22BH-6-6 Barbed Tube Bulkhead Union 3/8-24 Brass

Product Description

The PARKER 22BH-6-6 is a barbed tube bulkhead union designed to route tubing through a panel, bulkhead, or enclosure wall while maintaining a secure, leak-resistant connection on both sides. The fitting accepts tubing with a 0.25 inch inside diameter and uses a 3/8-24 thread for panel mounting. Constructed from brass, it provides reliable corrosion resistance in a wide range of fluid transfer applications. Plumbers, HVAC technicians, and fluid system assemblers install this type of fitting when a tube line must pass cleanly through a structural barrier without the need for additional hardware.

This bulkhead union is suited for low-pressure fluid or pneumatic tubing runs in residential and light commercial applications. Typical installations include HVAC drain lines, pneumatic control tubing, and fluid transfer circuits where a clean panel penetration is required. The barbed ends grip tubing mechanically, making assembly straightforward in tight spaces or confined equipment enclosures.

Key Features

• Bulkhead union design allows tubing to pass through a panel or wall with connections on each side
• Barbed ends provide a secure mechanical grip on flexible tubing without additional clamps
• 0.25 inch tube inside diameter for standard small-bore tubing
• 3/8-24 thread for panel or bulkhead mounting
• Brass construction offers corrosion resistance for water, air, and compatible fluid service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for small-bore flexible tubing systems requiring a bulkhead panel penetration with 3/8-24 thread mounting and 0.25 inch inside diameter tubing.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or fluid system technicians. Shut off all fluid or pneumatic pressure to the circuit before removing or installing any fitting. Ensure the panel or bulkhead hole is sized correctly for the 3/8-24 thread, and that the mating nut or locknut is tightened to secure the fitting firmly against the panel surface. Push flexible tubing fully onto the barbed ends to ensure a complete seal.
