Parameter guide

Plastic O-rings: what the parameters mean and how to choose the right values.

The clear inner diameter of the eye, that is the size of the opening something passes through. Rings are paired with a snap hook, webbing or chain by this figure: the mating part has to pass whole, not just its tip. The outer size of the piece is this diameter plus twice the material thickness.

The thickness of the plastic profile. At the same size plastic behaves differently from metal: a thinner profile is springier and opens up sooner under load, a thicker one keeps its shape but passes less easily through a narrow slot.
