Seal design engineers

PPE's team of seal design engineers are easily accessible to assist customers with component design and material development. Supported by extensive laboratory and materials testing capabilities, the PPE technical team can also provide detailed failure analysis reports on existing seals and suggest possible solutions. If you are a seal design engineer and can not seem to find the ideal sealing material or design for your application, the PPE seal design engineers can develop it for you.

FDA seal

FDA seals are typically used in food, dairy and pharmaceutical plants and equipment. PPE offers the most comprehensive range of elastomer compounds of any o-ring and seal manufacturer, with over 350 different grades. If you require an FDA seal, PPE has over 40 FDA compliant elastomer grades to choose from. In addition, PPE has a selection of perfluoroelastomer FDA seal grades with FCN (Food Contact Notification) approval.

High pressure seals

High pressure seals are typically used in compressors, hydraulic systems, injectors (engine) and various oilfield applications. Permeation of a gas into an elastomer under high pressure will not result in any long term effect provided the pressure is released gradually, allowing the gas to permeate out of the elastomer. However, if the pressure is released rapidly, the pressurised gas can expand explosively, rupturing the elastomer in a catastrophic manner. PPE offers a selection of Explosive Decompression (ED) resistant compounds to produce high pressure seals which eliminate this problem.
