Case Study: How DuPont Kalrez Seals Cut Costs

DuPont KalrezDuPont™ Kalrez® – Total Cost of Ownership Analysis

The drive to reduce costs and environmental concerns have caused many design and processing engineers to turn to perfluoroelastomer sealing parts as the most cost-effective sealing solutions.  The value-in-use of perfluoroelastomer can be proven in operating conditions where conventional elastomers fail.  Even under less arduous conditions, DuPont Kalrez perfluoroelastomer seals can be the best solution, as they can last significantly longer than conventional sealing solutions.

Economics depend on the total system cost

When considering the economics of elastomeric seals, it is vital to look beyond the total cost related to the sealing solution.  The total system cost in use is the sum of the cost of the O-ring seal plus the installation cost plus the downtime cost (including loss of productivity through leakage and clean-up costs).
