Parts and Shapes Made For Demanding Applications
High-performance parts and shapes manufactured by DuPont are the leading choice when resistance, reliability and safety are top-of-mind.
DuPont parts and shapes are used in applications that include undersea oil and gas production, aerospace, transportation, semiconductor integrated circuits manufacturing and life sciences. Both Kalrez® and Vespel® finished parts are precision-made, for long-term performance that can help extend both equipment service life and maintenance intervals.
Parts and shapes from DuPont are supported by our material science experts and the quality assurance of ISO 9001 certification. DuPont engineers work closely with customers to help customers specify, design and deliver molded parts, shapes and seals at sites across Europe, Asia and the Americas. We collaborate with customers to help them meet their individual performance, design, cost, and durability requirements.

- Kalrez® for Aircraft Engine Seals
O-rings for Gas Sweetening Valves
Kalrez® 7090 perfluoroelastomer parts offer an excellent combination of chemical, Rapid Gas Decompression (RGD) resistance , and high temperature resistance for O-ring applications in gas sweetening valves that handle glycol-based solvents.
Kalrez® O-rings for H2S Removal
Amine units for hydrogen sulfide removal (H2S) at high temperatures use elastomers like Kalrez® Spectrum™ 6380 FFKM parts for resistance to amines. 6380 helps extend MTBR of valves and pumps in amine service.
Kalrez® for Aircraft Engine Seals
Kalrez® parts used for aircraft engine seals are designed with properties to work in extreme temperatures and withstand aggressive aerospace fluids, including jet fuels and lubricating oils.
Sealing Collaboration Pays Dividends in Chamber Cleaning
Chamber cleaning with NF3 / O2 plasma increased maintenance at Spansion due to seal erosion. Kalrez® 9100 parts improved productivity and reduced cost-of-ownership. Kalrez® 9100 parts were successfully qualified in both thin films and dry etch tools.
- Pharmaceutical Seals for CIP and SIP
- Vespel® ® CR-6100 Boiler Pumps
- Vespel® SP-21 Thrust Washers
Ball Transfer Units For Panel Makers
ISB and the DuPont™ Vespel® team collaborated to create high-performance ball transfer units for cleanroom environments essential to flat-panel display and solar panel assembly.
- Kalrez® KVSP™ valve stem packing saves 56.000 £
- Line Shaft Bearings for Pumps
Glass Handling Sweep-Out Fingers
Vespel® SCP-5050 sweep-out fingers and stacker bar inserts for glass handling help increase plant reliability and efficiency and reduce operating costs at Veda-Pack glass manufacturing sites
- Critical Seals in HDPCVD Processes
- Kalrez® Spectrum™ 6375 O-rings for PTFE replacement
Vespel® Case Rings Boost Pump Efficiency and Safety
The operator of a pipeline in the Southwestern U.S. was searching for a case ring material for pumps that would enable improved operating efficiency, increase equipment reliability and avoid the seizing or galling problems encountered with metal components. The metal components were replaced with Vespel® CR-6100 parts, and the results were impressive.
