Made with Viton, the leading material for resistance to gasoline exposure. This ExactFit™ x-ring replaces OEM part number 886.4.188.1A. OEM part number 886.5.049.1A is the original "round" o-ring which come from the factory.
We learned Ducati was administering this type of seal at the fuel flange when an OE gas tank is leaking. It has a extra sealing grooves that help prevent leaking. In depth: Viton is the transportation industry's top choice when it comes to fuel system sealing. Viton retains sealing force to prevent leaks even after compression for long periods in severe environments. After 100 hours in air at 150°C (302°F), Viton retains more than 90% of its original sealing force, while seals of nitrile retain 40%.
