Rubber made Diaphragm Seals isolate instruments and protect the gauge while allowing the instruments to feel the process pressure. These Diaphragm Seals are made using quality grade rubbers like Viton, silicon, Hypalon, ethylene propylene diene monomer, thermo plastic rubber, nitrile butadiene rubber, neoprene, poly tetra fluoro ethylene, poly urethane, styrene butadiene rubber or natural rubber. These Diaphragm Seals maintain a hardness that ranges from 30-80 Durometer. Rubber made Diaphragm Seals come in different sizes to suit industrial requirement.
