Outperforms metal O-rings
04 October 2016
Costly breakdowns caused by the deformation of metal O-ring seals where process operating conditions reach temperatures up to 300°C can be reduced or even virtually eliminated by utilising the DuPont Kalrez perfluoroelastomer (FFKM) O-ring seals.
In examples where FFKM products have replaced the OEM fitted metal seals, uninterrupted production periods in excess of 10 years have been experienced without any lost production due to seal failures. Scheduled maintenance periods can also be safely extended.
The Kalrez O-ring seals are available in the UK from authorised distributor Dichtomatik. Finished O-rings, custom shapes, sheet and cords are manufactured exclusively by DuPont from raw material right through to the finished products, and Kalrez is now the choice of elastomer for the most demanding sealing applications.
