Our Series 0406 Bored Straight Male JIC Bulkhead Adapters are designed to provide a secure, leak-free connection in hydraulic systems. These adapters are similar to standard JIC adapters but feature a unique design with a hole bored through the hex for added functionality. Made from high-quality carbon steel, they are ideal for applications where fluid flow needs to be routed through a bulkhead while maintaining the reliability of a 37-degree flare JIC connection. The bored hole allows for additional customizations, such as fluid transfer or venting, while still offering the robust performance and durability you expect from JIC fittings.
