Mahlkönig lists it as Bean Hopper Seal Ring 1pc, E65S / PEAK and supplies it as a single piece. As a 10-pack, Mahlkönig lists the seal ring for the same grinders under part number 700702. Mahlkönig does not name a material.

For anyone who wants to replace the bean hopper seal ring on their E65S, PEAK or K30. More parts are in Grinder Accessories and Spare Parts, the grinders themselves in our Mahlkönig Collection.
A grinder goes with a scale. For anyone who wants an affordable, precise scale: Normcore. If you want an app, Bluetooth and flow-rate display: Acaia. Suitable products for grinder care are in Machine and Grinder Cleaning. Our advice tool shows which grinder suits your machine.
Mahlkönig lists 702934 for the E65S, E65S GbW, E65W GbS and PEAK as well as the K30 2.0, K30 ES/VARIO and K30 VARIO AIR. If you are unsure, send us your model and serial number at [email protected].
Some retailers also list 702934 for the EK43. Mahlkönig lists a separate seal ring with part number 703757 for the EK43, EK43 S, EKK43 and K30 TWIN 2.0. We therefore do not list this ring as fitting the EK43.
Mahlkönig’s US shop also lists the E65T GbS. The international Mahlkönig shop does not. We follow the international shop and are happy to check the fit for the E65T GbS in advance.
You can see Mahlkönig grinders live in our showroom in Zürich Oerlikon (Hagenholzstrasse 50b). We are happy to confirm by email whether the spare part is on site: [email protected].
Tip from the roastery: The seal ring belongs on the bean hopper. What reaches the cup is decided by the bean. For most cups we recommend Cozy Chocolate and Nutty Delight, dense, round and chocolatey. For maximum body without acidity there is Very Nutty, and anyone who wants to discover something fruity will find it in Wild Peach. That is our recommendation, one of many.
You order directly through our online shop. If you have questions, we're happy to help — online or in person — with experience from our roastery, cafés and showrooms.
