Diaphragm Seals and Isolators
Find the optimal Ashcroft® diaphragm seals and isolation rings for your application by using the filtering options provided.
Ashcroft® diaphragm seals and isolation rings protect valuable instruments from potential damage caused by corrosive media or clogging from sludge or slurries, especially in wastewater processing. Diaphragm seals are offered in a variety of configurations with a wide selection of compatible wetted materials, such as 316 stainless steel, Monel and Tantalum. Isolation rings are available in different diameters for integration into piping systems. They provide a contiguous, flexible inner wall that deflects to equally pressurize the fill fluid into the pressure measuring device.Showing 1-12 of 10 products
