Premium Automotive AC Bulkhead Fittings & Plates
Ensure a professional, leak-free finish for your custom AC installation with our high-quality automotive AC bulkhead fittings. Designed to provide a secure pass-through for AC and heater lines through firewalls or radiator supports, these fittings replace messy rubber grommets with a clean, hard-mounted solution. Whether you are building a hot rod, restoring a classic, or upgrading a heavy-duty cooling system, our bulkhead connectors provide the structural integrity and sealing performance required for high-pressure air conditioning systems.

Why Use Bulkhead Fittings for Your AC System?
In automotive air conditioning, bulkhead fittings serve as the bridge between the engine compartment and the interior cabin. Using a dedicated bulkhead plate or individual beadlock bulkhead fitting offers several advantages:

Leak Prevention: Unlike simple pass-throughs, these fittings anchor your hoses securely, reducing vibration and the risk of refrigerant leaks.

Professional Aesthetics: Achieve a "show-quality" look by organizing your #6, #8, and #10 lines through a single, polished or black-anodized plate.

Enhanced Durability: Our fittings are manufactured from high-grade aluminum and steel to withstand the heat and pressure fluctuations of automotive environments.

Our Bulkhead Fitting Selection
We stock a comprehensive range of configurations to match any custom evaporator or condenser setup:

Bulkhead Plates: Available in 2-hole, 3-hole, and 4-hole designs in square, diamond, and rectangular shapes to fit your specific firewall real estate.

Beadlock Bulkhead Fittings: Secure your AC hoses with straight or 90-degree beadlock inserts (available in sizes #6, #8, and #10) designed for a permanent, crimped connection.

Heater Bulkheads: Specifically designed for heater hose integration, ensuring both your cooling and heating lines are managed with the same level of precision.

Complete Kits: Many of our bulkhead assemblies include the necessary O-rings and mounting nuts to ensure a vacuum-tight seal right out of the box.
