Material guide
Compare common options by fluid, temperature and typical use. We can help confirm the right grade for your application.
Common sealing materials
Each card shows where a material is commonly used, its temperature range and any important limitation.
Oil, fuel and hydraulic fluid resistance
Hydraulic systems, oil seals, general industry
A practical balance of performance and cost.
Weather, ozone, steam and water resistance
Water treatment, outdoor equipment, sanitary service
Generally not the first choice for petroleum-based oils.
Wide temperature range, flexibility and physiological inertness
Food equipment, medical devices, clean processes
General, food-contact and medical-grade options require application confirmation.
High temperature, oils, fuels and many chemicals
Chemical processing, automotive, rotating equipment
A strong general-purpose high-performance elastomer.
Broad chemical resistance and plasma resistance
Semiconductor, chemical, oil and gas, aerospace
Specify media, temperature and cycle conditions for grade selection.
Low friction and broad chemical inertness
Guide rings, backup rings, valves and pumps
Fillers such as bronze and carbon can add strength.
Additional elastomer and polymer options for specific operating conditions.
| Material | Reference temperature | Core strength | Typical uses | Selection note |
|---|---|---|---|---|
| NBRNitrile rubber | -30 to +120 °C | Oil, fuel and hydraulic fluid resistance | Hydraulic systems, oil seals, general industry | A practical balance of performance and cost. |
| HNBRHydrogenated nitrile rubber | -40 to +150 °C | Heat, ozone and oil resistance | Automotive systems, belts and high-temperature oil service | Useful when NBR needs more heat and aging resistance. |
| XNBRCarboxylated nitrile rubber | -35 to +150 °C | High tensile strength and abrasion resistance | Wear-resistant seals, rollers and dynamic components | Consider where mechanical wear is a leading failure mode. |
| EPDMEthylene propylene rubber | -50 to +150 °C | Weather, ozone, steam and water resistance | Water treatment, outdoor equipment, sanitary service | Generally not the first choice for petroleum-based oils. |
| VMQSilicone rubber | -60 to +200 °C | Wide temperature range, flexibility and physiological inertness | Food equipment, medical devices, clean processes | General, food-contact and medical-grade options require application confirmation. |
| CRChloroprene rubber | -40 to +120 °C | Weather, ozone and moderate oil resistance | Outdoor equipment, hoses and general industrial seals | A balanced general-purpose rubber option. |
| FKMFluorocarbon rubber | -20 to +200 °C | High temperature, oils, fuels and many chemicals | Chemical processing, automotive, rotating equipment | A strong general-purpose high-performance elastomer. |
| TFE-PTetrafluoroethylene-propylene rubber (AFLAS-type) | -2 to +230 °C | Acids, bases, steam and electrical insulation | Chemical processing, steam and severe alkaline service | Low-temperature performance is more limited than FKM. |

| ECOEpichlorohydrin rubber | -35 to +135 °C | Ozone, fuel and low-temperature balance | Automotive fuel systems, hoses and diaphragms | Often selected for hydrocarbon and ozone exposure together. |
| NRNatural rubber | -60 to +90 °C | High elasticity and tensile strength | Vibration isolation, general rubber parts and bumpers | Weather and oil resistance are limited. |
| SBRStyrene-butadiene rubber | -40 to +110 °C | General-purpose strength and abrasion resistance | General molded parts, hoses and vibration control | Not a first choice for oils or aromatic fuels. |
| IIRButyl rubber | -50 to +120 °C | Low gas permeability and water resistance | Gas sealing, diaphragms, hoses and barrier components | Good gas barrier behavior with limited oil resistance. |
| ACMAcrylate rubber | -25 to +150 °C | Heat and oil resistance with good aging behavior | Automotive seals, transmission and engine components | Cold flexibility is lower than NBR. |
Actual performance depends on the compound, hardness, dimensions and operating conditions. Please confirm the final material before production.
