Passing battery cables through a bulkhead panel or firewall can be a pain at best and can be dangerous if not done properly. With the heavy duty weatherproof flanged bulkhead connector from R2X Racing, you can safely route power from one side of a panel to the other while keeping it protected from the elements. The glass-filled nylon body has a flange with 4 mounting holes to secure it to the panel with screws or bolts, depending on your application. The included fiberglass reinforced silicone gasket seals the flange to the panel and keeps water, dirt, and debris out. The included rubber insulator boot fits cable sizes from 2 AWG to 2/0 AWG and fits snugly into the groove on the connector. The insulator boot has a IP65 weatherproof rating and meets USCG, ISO and ABYC safety requirements for energized terminals. The connector itself is easy to install. Simply drill a 1.375" hole for the main body of the connector and 4 small holes to match the mounting flange. The copper core of the connector allows for high energy transfer with little loss. Because of the flanged mounting design and nickel-plated steel shaft, this connector allows for higher torque than conventional bulkhead connectors with brass shafts. The connector is continuously rated for 440 amps at 12 vdc and can handle a maximum of 550 amps at 12 vdc for up to 12 minutes with an 80% duty cycle. R2X Racing prides itself on quality products that are manufactured in the USA. We stand behind our products, so if you have any issues, please feel free to reach out to us and we will make things right.
