The Wabco Double Diaphragm, part number 9253920020, is a genuine Wabco brake component designed for heavy-duty air brake systems. Double diaphragm brake chambers use two flexible diaphragms to apply braking force through both service and spring-actuated circuits, making them a common choice on commercial trucks and trailers where combined service and parking brake function is required in a single unit. Pro Gear and Transmission carries this genuine Wabco part. Call us to confirm proper fitment for your specific vehicle or axle configuration before ordering.
