Beiter O-Rings are made out of high-grade elastomere. The most important function is to fix a stabilisation but it also absorbs vibration and can work as a friction grip.

O-Rings absorb vibrations not only in the stabilisation, but also on the Sight Tunnel and the Scope, thereby preventing them working loose.
When in conjunction with the Sight Tunnel, the O-Rings are working as a friction, allowing the pin to be turned without loosing any nuts!
In combination with a serving tool, an O-Ring allows an even tension of the filament while winding. In the Beiter Winder it is integrated in the system.
