Spare teflon ring

Brand: Beisan Systems

BMW vanos units have been consistently diagnosed to fail due to deteriorating piston seal O-rings.
The O-rings are made of a material that is failing in the engine environment.
This causes the vanos piston seals to lose their sealing function and for the vanos unit to fail.
Vanos seals repair kits are now available. Beisan Systems kits incorporate upgraded O-rings to address the failure mode and replacement Teflon seal rings.
