Import Back Up Ring — Buy in Bulk from Supplier in China

The backup ring from Xiamen Fumao Seal Co., Ltd. is a precision-engineered component designed to prevent extrusion in hydraulic and pneumatic systems. It is manufactured to withstand high-pressure conditions, ensuring the longevity of primary seals in dynamic applications. The ring is compatible with a variety of seal types, making it suitable for use in industries such as oil and gas, manufacturing, and automotive where reliable sealing is critical for operational efficiency.

Constructed from durable materials, this backup ring is built to resist wear and deformation under mechanical stress. Industry standards for such components typically include materials like PTFE, Nylon, or PEEK, with hardness ratings ranging from 70 to 90 Shore D. The design often incorporates a split or solid configuration, depending on the application, and is precision-machined to tight tolerances to ensure a snug fit within the gland. Typical dimensions for backup rings include inner diameters from 10 mm to 500 mm, with cross-sections of 2 mm to 20 mm, though exact measurements should be confirmed with the supplier.

Industrial buyers use backup rings to protect O-rings, U-seals, and other elastomeric seals from damage caused by pressure spikes or gap extrusion. They are particularly valuable in heavy-duty machinery where seal failure can lead to costly downtime. Xiamen Fumao Seal Co., Ltd. offers these components with flexible bulk trade terms, including FOB or CIF shipping options. Buyers should confirm packaging specifications, as standard industry practice often includes vacuum-sealed bags or cardboard boxes to prevent contamination during transit.
