The unique stepped boss design of this rubber diaphragm delivers precise alignment during assembly. When pressure changes, the diaphragm flexibly deforms and rebounds to control fluid or gas flow, while isolating different media inside the equipment. You can choose different rubber materials to achieve resistance to oil, high temperature, ozone and various chemicals. Custom molding can realize special stepped shapes that standard flat diaphragms cannot achieve.
This custom step rubber diaphragm is widely used in valves, pumps, pressure regulators and other industrial fluid control systems as core sealing and pressure sensing parts. Send your drawings or samples to get your customized quotation.
