Precision Sealing for Valves & Pumps
From diaphragm valves to hydraulic actuators, our precision-engineered rubber components deliver leak-proof performance, chemical resistance, and long service life across critical fluid handling systems.
What this sector demands
Reliable sealing is critical to maintaining efficient fluid flow. Our precision diaphragms, seals, and O-rings are engineered to prevent leakage, withstand varying pressures, and deliver consistent performance in valves, pumps, and flow control systems. Component selection in fluid control depends on the fluid being handled, the temperature and pressure range, and the wider service environment which is why we develop each part around its application rather than working from a catalogue. For this industry we manufacture fabric-reinforced diaphragms, butterfly seals, and customised precision rubber components. From initial idea through prototype to full production, Harkesh Rubber works alongside you at every stage with short lead times and the in-house capability to make it happen.
Our seals are manufactured from compounds developed to meet the approvals this industry demands, including WRAS, NSF 61, FDA, and RGD (rapid gas decompression) resistance with material qualification available to customer-specific standards.
