BGM PRO shaft sealing rings made of high-quality and ethanol-resistant (E10) FKM/Viton®*
WHY FKM/VITON®
The material FKM (fluorocarbon rubber) is extremely resistant to heat, friction and fuel/ethanol.
Current super fuel in Germany already contains up to 5% ethanol per se. In other countries the ethanol/alcohol content is significantly higher.
Conventional shaft seals can swell or soften on contact with fuels containing ethanol. The BGM PRO FKM/Viton® rotary shaft seals offer perfect protection against this.
In addition, Viton is twice as temperature resistant as conventional (blue) NBR shaft seals, has very good gas impermeability and is also very resistant to ageing.
FIT
FOR A motor equipped with BGM PRO FKM/Viton® shaft seals can therefore also be used without any problems in motors that run on E10 fuel (10% alcohol content).
The high-quality brown Viton®* sealing material is permanently resistant to alcohol and is also suitable for engines with high temperature loads and high speeds.
BGM PRO FKM/Viton® shaft seals are therefore suitable for all engines, whether original or tuned high-performance engines.
For reasons of environmental protection and in favour of a maximum flexibility of the sealing lip, we deliberately do not apply any additional PTFE/Teflon®* to the sealing lip.
ADVANTAGES BGM PRO
The BGM PRO shaft sealing rings offer double sealing as an additional feature. All rotary shaft seals that seal against the atmosphere have a so-called dust lip. This is positioned before the actual sealing lip and keeps dust, dirt and moisture away. This further increases the already good stability.
AVAILABLE
The BGM PRO FKM/Viton® oil seals are available individually as well as in sets for almost all Vespa and Lambrettas engines.
