Rubber diaphragms
About
Rubber diaphragms are flexible rubber membranes typically made from elastomeric materials like rubber or synthetic polymers that resists leakages & friction between two chambers by creating a seal. It is engineered to perform specific functions such as sealing actuation, pressure regulation or vibration isolation.
We at Harkesh Rubber are currently the best manufacturers of reinforced and non-reinforced type Diaphragms and are supplying to some of the major OEM’s across the globe.The development of customized solutions for special applications is our passion. For more than 2 decades we have been developing tailor-made solutions in close collaboration with our customers, for challenging fields of application that simply require more than a standardized valve product. This has resulted in countless variations. We have developed diaphragms for series production, and can also manufacture in small batches for selected applications. We can only show the tip of the iceberg here. Challenge us!
