This black concave cup-style rubber diaphragm is a custom molded flexible sealing component made of premium rubber compound. We support custom production according to your drawings or samples to fit your equipment installation and working conditions.
√ Concave cup-shaped design, optimized structure for pressure response and elastic rebound√ Multiple material options: NBR, Silicone, EPDM, FKM, HNBR and high fluororubber
√ Excellent sealing performance, prevents medium leakage under fluctuating pressure√ Reliable pressure transmission, separates fluids and gases while transferring pressure signals
√ Outstanding wear and aging resistance, stable performance under repeated deformation cycles
√ Customizable diameter, center hole size, thickness and hardness to meet your requirements
The concave cup profile of this rubber diaphragm provides larger elastic deformation range compared with flat diaphragms. When pressure changes, it flexibly stretches and rebounds to control media flow and maintain isolation between different medium chambers. You can select different rubber materials to resist oil, high temperature, ozone and various chemical solvents. Custom molding can achieve special concave shapes that standard diaphragms cannot match.
This custom cup rubber diaphragm is widely used in valves, water pumps, pressure regulators and industrial fluid control systems as core sealing and pressure sensing parts. Please send your drawings or samples for a customized quotation.
