O-ring for racing and tuning cylinder heads of Puch Maxi S / N, Puch X30 Sport NS / NL, Puch X30 Sport N-2AH, as well as rebuilt Puch Supermaxi LG1 & LG2 mopeds / mopeds.
This O-ring made of fluorine rubber FPM / FKM (commonly known as Viton) is temperature-resistant up to 200°C and therefore significantly more resilient than conventional NBR sealing rings. It offers outstanding resistance to oils, fuels and chemicals and is ideal for demanding applications with high temperatures or aggressive media.
The sealing ring can only be used on cylinder heads with a corresponding groove. You can find a selection of these in the accessories section.
