Have it your way! Zirgo's customizable AC bulkhead system provides a custom solution for feeding your hoses through your vehicle's firewall. Drilling a bunch of individual holes of different sizes in your firewall to feed your hoses through is both tedious and unsightly. A Zirgo AC bulkhead makes installation clean and easy.
Instead of having to buy pre-configured bulkhead sizes and layouts, the Zirgo customizable bulkhead system allows you to choose your plate size and configuration and then choose individual connector sizes for a completely custom solution.
Zirgo bulkheads feature corrosion resistant design and materials, and are CAD engineered for precise installation and effectiveness. Easy to install and features a Limited Lifetime Warranty.
