Questions about this O-ring
How do I confirm this is the right size?
Measure the inside diameter and the cross section of the ring you are replacing, or read them from the drawing. This listing is 12.00 × 1.00 mm. For a used ring, measure in several places; wear and swelling change the dimensions. Measurement guide
How is the price calculated?
The price shown is the total for one pack. The per-piece price is shown beside it for comparison. Choose how many packs you need; taxes and shipping are calculated at checkout.
Can I order a quantity that is not in the pack list?
Yes. Order several packs, or request a quote for larger or scheduled quantities.
Is the size reference a certification?
No. A size reference such as AS568 or ISO 3601 describes nominal dimensions. It does not certify the compound or approve the part for a specific application.
