Silicon Carbide Seal Rings


Providing you the best range of Industrial Seals such as Mixer Wet Seals, Double Mechanical Seals, Reactor Dry Seals, Metal Rubber Seal, Specially Designed Seals, Tungsten Carbide Seal Rings and many more items with effective & timely delivery.

They have the property of excellent resistant-corrosion, high mechanical strength, high thermal conductivity, good self-lubrication used as seal faces, bearings and tubes in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, pharmaceutical, auto industry and so on. When the sic faces are combined with graphite faces the friction is the smallest and they can be made into mechanical seals which are able to work in highest working requirements.
