Streamline your plumbing with the FLF Bulkhead Mounting Flange—the cleanest solution for securing AN bulkhead adapter fittings to firewalls, panels, or any flat surface. Engineered to eliminate clutter and simplify installation, this flange allows for direct threading, removing the mandatory requirement for a secondary backing nut. These are especially useful when you have difficulty accessing the other side of the panel.

Key Features:

• American Excellence: Proudly CNC machined in the USA from premium, American-sourced 6061-T6 aluminum.
• Integrated Threading: Features a precision-threaded bore, allowing the bulkhead to fasten directly to the flange for a low-profile, secure fit.
• Versatile Mounting: Designed for universal application across firewalls, fuel cells, or custom bulkheads.
• Race-Ready Security: While designed for direct threading, it is compatible with a secondary bulkhead nut for maximum vibration resistance in high-stress environments.

> Pro Tip: For high-vibration racing or off-road applications, we recommend the use of a thread-locking compound to ensure a permanent, fail-safe seal.
