EPDM material notes

Usually a good starting point for

Ozone/weathering, inorganic acids, alkalis, phosphate esters and many polar-fluid services.

Review before use with

Mineral oils and fuels are not default EPDM service; hot-water and steam use remains condition-dependent.

Family-level screening, not an approval of a specific compound. Screen a chemical or ask for a material check.

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 × 1.50 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.
