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.
