Diaphragm seals offer an ideal solution where accurate, consistent response is required for changes in hydraulic or pneumatic pressures with zero leakage, low friction and no lubrication.


Used in many industries including; automotive, aerospace, medical, instrumentation and process control industries, they offer an inexpensive solution to design problems.


Our manufacturing facilities have a broad range of moulding capabilities, with the ability to produce diaphragms from as small as 12mm diameter, up to 1168mm in diameter. As well as fabric reinforced diaphragm seals, we can offer an extensive range of plastic and rubber moulded diaphragms.

Ceetak Diaphragm seals are used in a wide variety of industries and can be manufactured in the following rubber and plastic materials:


• Nitrile (NBR)
• Fluorocarbon (FKM)
• Hydrogenated Nitrile (HNBR)
• Polyacrylate (ACM)
• Ethylene Propylene Diene Monomer (EPDM)
• Silicone (VMQ)
• Fluorosilicone (FVMQ)
• Chloroprene (CR)
• Perfluoroelastomers (FFKM)
• Polyurethane (PU)
• Santoprene
• Hytrel


Ceetak elastomer Diaphragm seals are also available with fabric reinforcement if required. Depending on application requirements, fabric reinforced materials include:


• Polyester
• Nylon
• High temperature Nylon
• Silk


Our Application Engineers can assist and advise in profile and material selection for the perfect diaphragm sealing solution for your application.
