Oil seal 22,7x47x7/7,5mm -MALOSSI PTFE/FKM- (used for crankshaft drive side Vespa V50, V90, SS50, SS90, PV125, ET3, PK S, PK XL - gear box input shaft Piaggio 125-180 cc 2-stroke, Piaggio 125 cc 4-stroke (1st generation))

Malossi uses the best materials for its oil seals. They consist of steel cores coated with fluorocarbon rubber (FKM/FPM). The inner running surface, which is in direct contact with the sealing surface of the crankshaft, is made of PTFE(polytetrafluoroethylene). Both materials are known under the trade names FKM and Teflon from the manufacturer DuPont. PTFE is extremely resistant to all acids, oils, greases, alcohols and fuels. Due to the increased alcohol content in today's fuel, shaft seals with this material are recommended. In addition to their tremendous wear resistance, they run with low friction which makes them mandatory for all higher revving engines. Piaggio uses PTFE rings as standard in the 125-180cc two-stroke engines such as the Runner or SKR. Also in the PX engines the clutch side big shaft seal of the crankshaft is made of such a material (brown sealing lip).

• Very low wear
• Absolutely heat resistant
• Extremely low frictional resistance
• Resistant to almost all chemicals
• Perfectly suited for heavily tuned engines
• Can also be used in series engines
