Quick questions

Short answers before you use the product table below.

What does ID × CS mean?

ID is the inner diameter. CS is the cross section, or ring thickness. Product sizes are shown in mm first, with inch references where available.

Which material should I start with?

NBR is common for many oil and general repair needs, FKM is often selected for fuel and higher temperature applications, EPDM is common for water and outdoor use, and Silicone is useful where flexibility is important.

What if I only know an AS568 dash number?

Use the search bar or Size Guide to match the dash number to the correct ID and CS, then filter this collection by material and hardness.

When should I use Bulk Quote instead?

Use Bulk Quote for 1000+ pcs, non-standard sizes, special materials, drawings, samples, photos, or compatibility review.
