Import British Standard Flexible Rubber Joint — Buy in wholesale FOB from Supplier in China

The British Standard Flexible Rubber Joint from Henan Shunying New Energy Co., Ltd. is a pipeline vibration-dampening fitting designed to absorb displacement, axial expansion, and mechanical stress in fluid transport systems. Manufactured to GB4216.3-4216.5 flange connection standards, it is offered in working pressure ratings of 10 bar, 16 bar, and 25 bar, with corresponding burst pressures values of 30 bar, 48 bar, and 55 bar. Vacuum resistance is rated at 400 mm Hg, 650 mm Hg, and 750 mm Hg respectively. The body is moulded polar rubber, selected for its elasticity and chemical compatibility across varied service conditions.

Material variants include acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, and heat-resistant compounds, allowing adaptation to different media and operating environments. The construction keeps axial dimensions minimal and mass low, which reduces warping forces on connected equipment. Sealing is achieved through the inherent resilience of the polar rubber compound rather than auxiliary gaskets. Installation requires diagonal bolt tightening for overhead runs, with elastic support recommended for suspended pipelines. At elevated pressures, bolted flange connections at both ends become mandatory to retain joint integrity under cyclic loading.

Typical buyers include municipal water works, HVAC contractors, petrochemical plant engineers, and shipyard piping specialists who need to isolate pump or compressor vibration from fixed infrastructure. The acoustic damping capacity suits noise-sensitive installations such as hospitals, hotels, and commercial buildings. For import orders, buyers should confirm the required pressure class, flange drilling pattern compatibility with existing pipework, and the specific rubber compound suited to their media. The supplier's location in Zhengzhou, Henan Province, places it within China's central manufacturing corridor with rail and road access to Tianjin and Qingdao ports.

Henan Shunying New Energy Co., Ltd. is headquartered at Room 519, 8th Floor, Unit 2, Building 1, No. 33 Jinsuo Road, High-Tech Zone, Zhengzhou, Henan Province, China. The supplier holds a harbor trust tier on the platform, with a response rate currently showing 0.00 percent and no recorded average response hours. This profile indicates limited transactional history or engagement data is visible to buyers at this stage. The company lists itself in the new energy sector but offers industrial pipeline components including this British Standard Flexible Rubber Joint.

The source description does not state year of establishment, factory size, number of employees, annual revenue, named clients, or specific quality management certifications such as ISO 9001. No MOQ, unit price, or packaging details are provided in the available data. Buyers should therefore request a company profile, factory audit report, and reference customers directly from the supplier before committing to volume orders. The Zhengzhou location suggests proximity to Henan's rubber and polymer processing cluster, but this should be verified through direct communication.
