Yuanbo Engineering Co., Ltd supplies oxygen‑free copper gaskets that are stamped from 1/4‑hard high‑purity copper stock. The catalogue lists ten standard dimensions, for example CG‑01 with an outer diameter of 16 mm, inner diameter 12 mm and thickness 2 mm, up to CG‑10 with OD 294 mm, ID 269 mm and the same 2 mm thickness. All parts are solid copper without any coating, offering a soft metal that can conform to mating surfaces. The company also offers custom shapes on request.
Copper’s intrinsic thermal conductivity and oil‑resistance make these gaskets suitable for high‑temperature engine environments. Typical tensile strength for oxygen‑free copper is around 32 000 psi, and the material exhibits a 25 % coefficient of elasticity, which helps maintain joint integrity under vibration. In the sealing industry, such gaskets are often produced to meet ASME B16.5 flange standards, although the supplier does not explicitly state certification. Standard industry practice calls for a hardness of 40‑60 HRB for 1/4‑hard copper, which aligns with the material described.
Primary users include automotive manufacturers, aerospace engine builders and pipeline installers who require reliable leak‑proof joints. Yuanbo can ship bulk quantities in wooden crates or cardboard boxes, and the listing notes that special sizes can be fabricated to match non‑standard flange dimensions. Buyers should confirm minimum order quantities, preferred Incoterms and payment terms directly with the supplier, as these details are not disclosed in the public data.

Before placing an order, verify that the copper material meets the required purity level and that any custom dimensions are clearly detailed in a technical drawing. Request confirmation of any certifications, such as compliance with ASME B16.5, and ask the supplier to provide a material test report to ensure the gasket will perform under the intended pressure and temperature conditions.
When arranging shipment, ask the supplier which Incoterms they can offer, as the public data does not specify this information. Confirm the expected lead time for standard and custom sizes, and negotiate payment terms that align with your company’s risk management policy. Shipping by sea in bulk crates is common for these products, but air freight may be possible for urgent small‑batch orders.
Upon receipt, conduct a visual inspection for surface defects and verify dimensions against the supplied drawing. Request a tensile‑strength test report and, if required, a non‑destructive pressure test to confirm sealing capability. Keep records of the supplier’s material certification and any inspection certificates for future quality audits.
