Key Benefits
- Complete mould set for the AS568 size range, so standard sizes are produced quickly
- An internationally recognised size standard that designers and maintenance teams already work to
- Available in the compound your application needs rather than one fixed material
- Covers almost every category of mechanical equipment
- Convenient sourcing for maintenance kits and production alike
Problems It Solves
- Long waits for tooling on sizes that should be standard
- Mixed size standards across a maintenance store
- Seals ordered by nominal size and arriving with the wrong cross section
- Compound and size specified separately and getting out of step

Compared With The Alternatives
| Metric O-ring sizes | AS568 is the imperial based standard used across much of global machinery; metric sizes exist alongside it. Confirm which your equipment was designed to before ordering. |
|---|---|
| Custom sizes | Standard AS568 sizes are quicker and cheaper because the moulds already exist; custom sizes are for grooves that no standard dash number fits. |
Use Guide
- Quote the dash number and the compound together, since the same size exists in every material
- Check the cross section as well as the inside diameter when identifying a used seal
- Standardise on AS568 across a product family to simplify spares
- Colour code compounds in the store to avoid mixing them up
Questions
Questions Buyers Ask About This Product
Do you hold moulds for the whole AS568 range?
Yes, which is why standard AS568 series parts can be supplied promptly and conveniently.
Which compounds are available in AS568 sizes?
The standard compounds including NBR, HNBR, EPDM, FKM and FFKM. Specify the compound with the dash number.
Can you supply sizes outside the AS568 series?
Yes, custom sizes are produced to drawing.
Which industries use these O-rings?
Machine tools, agricultural, construction, engineering, mining, plastic, petroleum and chemical machinery, automobiles, ships and aerospace equipment among others.
How do I identify the size I need?
Give the dash number if you have it, or measure the inside diameter and cross section of the old seal and the groove dimensions.
