Kalrez® O-Rings and Seals

Aircraft and Aerospace Industry

Aircraft and Aerospace: Where Other Elastomers Fail, Specify Kalrez®

The ability to withstand extreme temperatures makes Kalrez® perfluoroelastomer parts ideal for use in aircraft and aerospace applications. Kalrez® parts also withstand aggressive aerospace fluids, including jet fuels, engine lubrication oils, hydraulic fluids, rocket propellants and oxidizers. Kalrez® has proven its superior performance for more than 25 years in such applications as:

• Aviation, marine and industrial gas turbine engines
• Auxiliary power units
• Hydraulic actuators
• Bleed air valves and fittings

DuPont Performance Elastomers Kalrez® seals combine the chemical inertness and thermal stability of fluoropolymer with the leak-stopping resilience of an elastomer. The unique properties of Kalrez® can help you meet the most demanding sealing challenges, while allowing you to "design-in" benefits ranging from reduced downtime to lower operating costs to improved personnel safety.

Kalrez® for Unsurpassed Chemical Resistance

Unlike other elastomers, Kalrez® seals demonstrate virtually universal chemical compatibility. Kalrez® parts resist the most aggressive aerospace fluids, including hydraulic fluids, jet fuels, hot lubricating oils, oxidizers, rocket propellants, solvents and degreasers, as well as hot air.

Reducing Costs and Downtime While Increasing Safety

DuPont Performance Elastomers' Kalrez® seals combine the chemical inertness and thermal stability of fluoropolymer with the leak-stopping resilience of an elastomer. The unique properties of Kalrez® can help you meet the most demanding sealing challenges, while allowing you to "design-in" benefits ranging from reduced downtime, to lower operating costs, to improved personnel safety.
