The Oil Lubrication Stern Tube Sealing Apparatus supplied by Shandong Wantong Euro-Asian Marine Engineering Co., Ltd. is a composite seal designed for marine propulsion shafts. It combines a stainless‑steel 316L housing with NBR and FKM elastomer sealing elements. The unit is intended for vessels with a loaded draft under 20 m and shaft speeds up to the typical range for work boats and military ships. Dimensional matching to the shaft diameter is required according to the vessel class specifications.
Stainless‑steel 316L offers corrosion resistance in seawater, while NBR provides oil resistance and FKM adds high‑temperature stability. In the marine sealing market, similar devices are classified as mechanical seals with elastomeric lips and are tested against IMO Type Approval standards. Typical operating temperature for such seals ranges from - 30 °C to 150 °C and pressure ratings reach up to 5 bar.
The apparatus is used on ocean‑transport vessels, work boats, military ships and inland waterway craft that require reliable oil containment at the stern tube exit. Shipyards, retro‑fit contractors and naval procurement agencies are the primary buyers. Suppliers usually request detailed shaft dimensions and class society requirements before quoting, and they may offer crate or pallet packaging with standard incoterms such as CIF or FOB. Interested parties should confirm minimum order quantities, lead times and payment conditions directly with the manufacturer.

Before placing an order, importers should obtain the detailed engineering drawing of the seal and verify that the housing diameter and elastomer profile match the shaft dimensions of the target vessel. Request the supplier’s certification of material grade, such as a mill test report for the 316 L stainless steel, and confirm compliance with the relevant IMO or classification society standards. Any deviation from the specified dimensions can lead to costly re‑work during installation.
Shipping is typically arranged on a CIF or FOB basis, with the seal packed in a reinforced crate and placed on a standard 20‑foot container for bulk quantities. Buyers need to clarify the incoterm, expected lead time and whether the supplier can provide a shipping schedule aligned with the vessel’s construction timeline. Payment terms are usually negotiated as a letter of credit or advance payment, and should be documented in the sales contract.
Quality assurance commonly includes a factory acceptance test that checks leakage at the rated pressure and a dimensional inspection using calibrated gauges. Importers are advised to engage an independent marine surveyor to perform a pre‑shipment inspection and to request the test certificates, such as a pressure‑test report and material certification. Maintaining records of these documents will facilitate class‑society approval and future warranty claims.
