How to detect the size of the o-ring?
The standard O-ring can be measured with a cone-shaped mold. Put the O-ring on the cone and use gravity to fall naturally. The inner diameter of the O-ring can be measured. As for the wire diameter, it can be measured by three-coordinates. The ring is elastic, and the accuracy is not very high. The size changes greatly after stretching. If you feel that the vernier caliper is not accurate enough, you can use a three-coordinate projector, but I personally think it is unnecessary.
test tools:
Seal ring inner diameter measuring ruler, O-shaped rubber ring inner diameter measuring ruler
Sealing ring inner diameter pie rule: used to measure the average inner diameter of flexible materials and rigid materials and to accurately measure the average inner diameter or outer diameter of O-shaped rubber seals.
Application range: O-rings, vacuum rubber gaskets, rotary seals, etc.
