Choosing the correct seal

Match the complete cutting head model and the existing seal's dimensions before ordering. The four-number size labels are reproduced in the same order as the supplied AU3TECH store listing; confirm their measurement conventions with the original component. If unsure, send a clear photo of the head nameplate and used seal for a fit check. The main image illustrates the range; appearance may vary by variant.

Shipping, Compatibility & Returns

Courier freight is confirmed by destination, weight and carton size. We normally ship by DHL, UPS or FedEx with tracking.

If you are unsure about compatibility, send the cutting-head model, source model, part code or dimensions before ordering. Custom, special-order and opened optical parts are handled according to the agreed order terms.
