Buyer Guides

Start with OEM/ODM or sealing materials if you need custom marking or compound selection. Trade policy, cross-reference, About and the inquiry form cover MOQ, equivalents, certificates and RFQ.

• MOQ, lead time and payment — Published MOQ, lead time, payment and packing terms are on the trade policy page. A firm schedule follows a formal quotation.
• OEM / ODM and custom — OEM/ODM and custom marking are available for qualified B2B orders. Share drawings or samples via the inquiry form.
• Materials and selection — Compound selection (NBR, FKM and others) depends on media, temperature and pressure. Confirm the grade on the product specification and on the quotation.
• Part cross-reference — Search equivalent part numbers on the cross-reference page. Confirm dimensions and material before substituting.
• Quality, inspection and certificates — Factory quality control and certificates are described on the About pages. Ask sales for the current certificate list.
• Samples and RFQ — Request a quotation or sample with size, material, quantity and destination. Catalog list prices are not published here.
• How to check a replacement seal — Check replacement seals against drawing dimensions, profile, material and operating conditions. Treat cross-reference numbers as search aids until fitment is confirmed.
• WG9112340113 oil seal cross-reference checklist — Compare the catalog-listed WG9112340113 / WG9112340114 wheel hub seal dimensions and material, then confirm the drawing and assembly before ordering.
