Welcome to the HEL Performance range of high-quality, dependable and unrivalled oil system components. Our widely embraced, race-winning products have not only secured victories on the race track but have also been rigorously tested on the open road.
What sets us apart is simple yet significant; we handle the entire CNC machining process in-house for our complete range of oil system components. This gives us full control over the manufacturing process, leading to exceptional quality and faultless products. This commitment guarantees longevity and unwavering durability, even when used in the most demanding and challenging environments.
The HEL Performance twin bulkhead passthrough plate has been designed for seamless integration with vehicle bulkheads, firewalls, bespoke panels, and custom brackets. Its primary function is to facilitate the secure and dependable transfer of fuel, oil, air, and coolant between partitions. Featuring two fully threaded inlet and outlet ports, our bulkhead plate offers compatibility with a wide range of threaded adapters to accommodate a variety of hose and fitting configurations.
Adding to its robust, lightweight, and stylish design, our bulkhead plate features an integrated o-ring on the rear mounting face. This not only contributes to weather resistance but also establishes a watertight seal, reinforcing the reliability of the entire system.
For AN16 (-16) and AN20 (-20) hose requirements, please see our larger twin bulkhead passthrough plate.
Designed as a universal product, our twin bulkhead passthrough plate can be mounted to a variety of surfaces. To make it simple, we have included a drilling diagram to allow a simple and user-friendly installation.
