DO Type 168-203mm Floating Seal
The DO Type 168-203mm Floating Seal is a cast iron sealing element designed for demanding industrial equipment. It is forged from high‑chrome alloy casting iron, giving it a hardness between HRC60 and HRC72. The seal is rated for a continuous service life of up to 4,000 hours, which reduces replacement frequency. Dimensions cover an inner diameter of 168mm up to an outer diameter of 203mm, matching standard bore sizes used in heavy‑duty machinery.
The seal can be fitted with four standard rubber O‑ring compounds - NBR, VMQ, HNBR and FPM - allowing selection according to temperature and chemical exposure. In the sealing industry, high‑chrome alloy casting iron is the typical material for floating seals that must endure high pressure and abrasive media. A hardness of HRC60‑72 is a standard range that provides wear resistance while maintaining enough elasticity for sealing action. Typical operating pressure for seals of this size is up to 20 MPa, and the common temperature window is - 30°C to +200°C.
This floating seal is commonly installed in machinery, automotive power units and marine propulsion systems where leak‑free operation is critical. Buyers such as OEMs of heavy equipment and contract manufacturers often request FOB or CIF shipping from the supplier’s Beijing facility. The supplier offers flexible minimum order quantities and ships the seals in robust wooden crates or metal pallets to prevent damage. Prospective importers should confirm the exact O‑ring material, packaging details and any required ISO or SGS certificates directly with the supplier.

Sourcing DO Type 168-203mm Floating Seal from Beijing Zhongnuo Sealing Technology Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact inner and outer diameters, confirm the selected O‑ring material, and request copies of any ISO 9001 or SGS inspection reports to ensure the seal meets the required quality standards. Checking the supplier’s packaging method - wooden crate or metal pallet - helps avoid damage during transit and simplifies customs handling.
Logistics for this product are usually arranged under FOB or CIF terms from the Beijing shipping point. Buyers need to confirm the expected lead time, which is not stated in the listing, and negotiate payment conditions such as T/T or LC to match corporate risk policies. Clarifying the incoterm details early prevents unexpected costs at the port of entry.
Quality assurance typically involves a visual inspection of the casting surface, hardness testing to confirm the HRC60‑72 range, and a dimensional check of the bore sizes. Importers should also arrange for a third‑party inspection agency to verify the seal’s compliance with the supplied specifications and obtain a certificate of conformity before shipment.
