Browse our range of CAT-style split flanges, clamps, seals and associated connection components, selected for high-pressure hydraulic connections used on heavy mobile equipment. Confirm the working pressure, fluid compatibility, thread or flange standard and required size before ordering. Hydraulic components that look similar are not always interchangeable, so matching the complete specification helps prevent leakage, restriction and premature failure. Explore the available options online, or contact Fluid-Air Components if you need help identifying a compatible product or cross-referencing an existing component.
