Diaphragm Seals -
Diaphragm seals are devices that seal pressure transmitters to prevent process fluid from coming into contact with the inner workings of the transmitter. Centro's diaphragm seals are made from high-quality rubber resistant to wear and tear. They are available in various sizes to fit most pressure transmitters. Centro carries a complete selection of diaphragm seals available to purchase online. In addition, Centro offers a wide range of accessories for diaphragm seals, including replacement diaphragms, o-rings, and mounting brackets. Whether you need a single diaphragm seal or a complete Diaphragm Seal kit, Centro has the products to keep your pressure transmitter working correctly.
