Frequently asked questions

Straight answers on MOQ, lead time, samples, custom tooling, standards and shipping.

What is your MOQ?

MOQ depends on the item, size and whether a new mould is needed. Send the model, dimensions and target quantity on WhatsApp and we will confirm it in writing.

Can you make custom or non-standard sizes?

Yes. Send a drawing, a sample, or the d × D × W dimensions plus the working medium and temperature. We will confirm tooling, sampling and MOQ on WhatsApp.

Which materials do you offer?

NBR, FKM, EPDM, VMQ, HNBR, PU and copper are commonly available. See the Materials page for temperature, hardness and media compatibility, then tell us the working conditions.

Which standards do the seals follow?

Rotary shaft seals are commonly specified to DIN 3760 / ISO 6194 and O-rings to ISO 3601 / AS568. Confirm the exact standard and tolerance you need when enquiring.

Can I get samples or a test report?

Ask on WhatsApp with the model and quantity. Sample policy, available certificates and third-party test reports will be confirmed per order.

What is the lead time?

Lead time depends on whether the size is in stock and whether tooling is required. Confirm the current schedule on WhatsApp before placing an order.

How do I request a quote?

Click any Chat on WhatsApp button on this site. On product pages the message is pre-filled with the product name, so you only need to add size and quantity and press send.

Do you ship internationally?

Tell us the destination country and quantity on WhatsApp and we will confirm packing, shipping options and Incoterms for your order.

We have deliberately left out invented numbers for MOQ, lead time and price. Send your real policies and we will put them here — specific, verifiable answers convert far better than vague promises.

Still have a question?

Ask directly on WhatsApp. A real person answers with the current MOQ, lead time and shipping options.
