Import China Flexible Rubber Bellow — Buy in wholesale FOB from Supplier in China

The China Flexible Rubber Bellow from Zhengzhou Mason Pipe Fittings Co., Ltd. is a precision-engineered component designed to absorb mechanical vibration, compensate for axial and lateral misalignment, and isolate piping systems from thermal expansion. It is constructed from industrial-grade synthetic rubber, with reinforcement layers of polyester or nylon fabric, and metal flanges compatible with standard piping systems. The product is available in nominal diameters ranging from 25 mm to 300 mm and lengths up to 500 mm, as specified in the source listing.

The rubber compound used is typically NBR or EPDM, chosen for resistance to oils, ozone, and moderate temperature extremes between -20°C and +110°C. These materials are standard in industrial bellows applications where chemical exposure or weathering is a concern. The internal structure includes multiple plies with embedded cord reinforcement, providing structural integrity without compromising flexibility. The flanges are carbon steel, often coated with zinc or epoxy for corrosion resistance, though material grade is not specified in the source.

This bellow is commonly used in automotive suspension systems, HVAC ducting, pump inlet/outlet connections, and industrial machinery where vibration damping is critical. Buyers include manufacturers of heavy equipment, plant engineers maintaining pipeline networks, and distributors serving the mechanical maintenance sector. Trade terms are typically FOB or CIF from Chinese ports, with packaging in wooden crates or cartons. Minimum order quantities are not stated and must be confirmed directly with the supplier.
