A rubber diaphragm is a flexible membrane made from elastomers like nitrile, EPDM, silicone, or neoprene. It acts as a barrier between two chambers, allowing pressure or fluid movement on one side while preventing leakage or mixing.
Commonly used in pumps, valves, regulators, and control systems, rubber diaphragms provide excellent sealing, flexibility, and chemical resistance. Molded or clamped between housings, the diaphragm flexes smoothly when pressure or force is applied, transferring motion or regulating pressure on the other side with precision and no friction.
