Applications
The FS2700-SS Bulkhead Union is critical for professional and organized hydraulic plumbing:
- Passing hydraulic lines through machine housings, operator cabs, vehicle firewalls, or control panels while maintaining a secure, sealed connection.
- Creating fixed external connection points on equipment, allowing for easy and repeatable connection of hose assemblies.
- Essential for robust plumbing in marine vessels, offshore platforms, chemical plants, and food processing equipment where lines must pass through barriers.
- Provides a clean, professional finish and prevents chafing or vibration damage to hoses and tubes passing through a panel cutout.
Installation & Usage Guidelines
- Drill or punch an appropriately sized hole in the panel or bulkhead. Ensure the surface is clean and flat.
- Insert the longer threaded end of the bulkhead union through the prepared hole.
- Thread the included locknut onto the fitting from the opposite side of the panel and tighten securely. Use a wrench on the fitting's hex to prevent it from rotating.
- Connect female ORFS swivel fittings to both male ends of the union, ensuring O-rings are lubricated and undamaged.
- Tighten both swivel nuts to the manufacturer's recommended torque.
