BGM PRO Vespa Oil Seal Set FKM/Viton®(E10 Ethanol Resistant) PX80, PX125, PX150, PX200, T5 125cc, Cosa, LML125/150 Star 2-stroke
The material FKM (fluorocarbon rubber) is extremely resistant to heat, friction and fuel/ethanol.
Current super fuel in United Kingdom 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.
