How can I order oil seal samples and confirm the MOQ?

Ask for separate sample, standard-stock and custom-production quantities. MOQ depends on the exact part, compound, tooling and quantity per size, so obtain a written quotation for each item.

Information to compare

• Part number and drawing
• quantity per size
• sample quantity
• tooling status and ownership
• quotation validity

Separate sample approval from production ordering

List the quantity required for dimensional checks, installation trials and operating tests. Ask whether samples use existing stock or require a production run and whether tooling is included in the sample price.

Request MOQ per part number, compound and packaging option. A combined order quantity can hide a minimum for each individual specification.

Agree the sample acceptance criteria and drawing revision before testing. Ask for separate sample and production dates, and record whether the production schedule starts after payment, tooling completion or written sample approval.

Certification, parameters and delivery

Ask for current certificates relevant to the manufacturing site and your purchasing requirements. Verify the document number, scope and validity. Match inspection records to the part and lot specified in your order.

State the dimensions, compound requirements and operating conditions you need confirmed. Request separate sample and production schedules, including the approval trigger, dispatch date and destination. VKEFOT certification availability, MOQ and delivery dates must be confirmed in the quotation for your selected part.
