SUPERSHELL GASOLINE Resistant O-Rings and Seals
SUPERSHELL GASOLINE is a fuel blend composed mainly of unleaded gasoline and ethanol. It is commonly used in automotive and recreational applications, such as boats and motorcycles.
Exposure of rubber seals and gaskets to SUPERSHELL GASOLINE can cause the rubber to become brittle and crack due to the plasticizing effect of the ethanol. In addition, the gasoline can cause the rubber to swell and lose its seal, resulting in leaks or other failures. Furthermore, the combination of ethanol and gasoline can cause the rubber to become more vulnerable to ozone attack and accelerated aging. Therefore, it is important to use rubber materials that are compatible with SUPERSHELL GASOLINE when designing seals and gaskets.
Buna-N (NBR, Nitrile, Buna)
Buna-N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.
