note : repair dupont lighter need to use special tools ,if you want ,can buy them on my stor Seals, Tools and Spare parts: is example video I want show you how to change seals of your S. this item only include repair kit (oring ), no dupont lighter. 2 pcs can services 2 lighter, 4 pcs can services for 4 lighter. This kit can services for dupont lighter ligne 2 or GATSBY model, repair leak gas. Learn more about high-heat uses for DuPont seals and gaskets. Increased mechanical seal life and MTBR (mean time between repair).Įxplore Vespel ® for oil and gas centrifugal pump parts.Improved performance, enabled by heat resistant plastics, can increase pump reliability and performance, while potentially cutting down on wasted fuel due to pump problems. This heat resistant plastic has replaced metal and other composite materials used for pump wear rings, throat bushings and line shaft bearings.
In order to increase mean time between repair (MTBR) and improve safety, the industry standard has long been DuPont ™ Kalrez ® perfluoroelastomer parts and seals.Īs new demands on production have raised that standard, DuPont has developed Kalrez ®Spectrum ™ products that can retain their elasticity and recovery properties better than previous generations of high-temperature elastomers, even after long-term exposure to temperatures up to 327 ☌ (620 ☏).ĭuPont ™ Vespel ® CR-6100 parts are working today in more than 5,000 pumps at oil refineries, petrochemical plants and power plants around the globe. Processing environments in chemical and hydrocarbon plants are running hotter, longer, and with more aggressive chemicals in the mix. Making Chemical Production More Efficient The combination of production qualities and thermal resistance enable efficient, high-quality production of reliable components. DuPont ™ Crastin ® PBT is used in solenoid valves that control water, air, steam and other gases.Ĭrastin ® can withstand highs of 150º and lows of -40 ✬, while maintaining adhesion to the copper wire during injection molding of the solenoid. Pumps, valves and solenoids need tough protection, as they often operate in hot engines and other equipment. See how Nissan™ Europe used Zytel ® to help lighten the engine housing. That kind of performance means automakers can count on hoses, CAC end tanks and other parts made with Zytel ® to replace metal components in higher-temperature loops, for cost and weight savings.
These three products also retained their strength between 75 to 100 percent better than nylon 66, and about 40 to 70 percent higher than that of PPS.

Zytel ® PLUS and Zytel ® HTN92 Series PPA maintain good strength after being exposed to 180 ✬ hot air for 3,000 hours. These heat resistant plastics offer a significant leap in thermal oxidation resistance, or long-term heat aging performance.Īpplying SHIELD technology enables Zytel ® PLUS polymers to provide improved resistance to hot-air aging. Higher acidity (through EGR (exhaust gas recirculation) condensates)ĭuPont ™ Zytel ® PLUS nylon and DuPont ™ Zytel ® HTN92 Series PPA resins are based on our proprietary SHIELD technology.
