O-Ring Size Chart
We specialize in producing o-rings of various sizes, colors and rubber materials.
Our company has nearly 2000 sets of ready-made o-ring molds (including the cover molds).
We can save mold costs for you, and also carry out small batch customization.
The sizes of o-rings in our current inventory range from 1(ID)*1(W) mm² to 670(ID)*7(W) mm²
How to measure o-rings: The o-ring is a circular ring, usually made of elastic rubber, whose size is determined by the Inner diameter (ID) and Wire diameter (W).
