/5 CYLINDER HEAD O-RINGS / Viton / *Sold as each* for /5 Airheads
/5 Cylinder Head O-Rings
These O-rings fit early to mid series /5 models under the rocker arm supports and seal the steel tube which the rocker sits on to prevent oil from leaking onto the fins. If you can see the steel tubes through the fins you need these O-rings.
The O-rings supplied by BMW are no longer the correct dimensions. Our O-rings are the correct material for the application and are the same dimensions as the original correct /5 O-rings.
*Please note*: The cylinder head castings on later /5 models enclosed the steel tubes inside the castings and the O-rings were no longer necessary.
