They are characteristically tough and dynamic and essential in many flow control applications. We provide full production capabilities from prototype and short run quantities through large production runs. Custom Gasket Mfg. takes pride in its ability to consistently produce precision custom rubber diaphragms guaranteed to meet your most stringent requirements and function perfectly within your application.
