Columbia's rubber diaphragms are versatile seals used in a wide range of applications to handle various fluids, air, and vacuum sealing and flow requirements. Our rubber diaphragms are custom-designed and engineered to operate for specific pressures and pressure changes, mechanical requirements, fluid interaction, and dynamic life.

Columbia's rubber diaphragms can be tuned for unique application characteristics through component and material design, to optimize final assembly performance and cost.

Rubber Diaphragms typically function within the application by transmitting pressure from one system to another without exchanging media between the systems. Columbia diaphragms can also be designed with integrated valves designed to seal up to a pressure threshold before allowing for the system to vent (leak). We offer 100% in-line computer controlled pressure testing of diaphragms for critical applications.
