Import 2" Heavy Duty No Hub Coupling — Buy in Bulk from Supplier in China

This 2-inch heavy duty no hub coupling from Richang Qiaoshan Trade Co. Ltd. is a mechanical fitting designed to join cast iron soil pipes without the need for hub-and-spigot caulking. The coupling uses a stainless steel shield and an elastomeric gasket to create a sealed, flexible joint. Its 'heavy duty' designation indicates a thicker shield and stronger gasket material intended for above-ground drainage, waste, and vent (DWV) systems where greater resistance to shear and deflection is required.

The coupling's shield is manufactured from 300 series stainless steel, which provides corrosion resistance suitable for most drainage environments. The gasket material is specified as EPDM or Neoprene, both common elastomers for DWV applications; EPDM is typically used for general drainage, while Neoprene offers better resistance to oils and certain chemicals. A 2-inch size is standard for branch lines in residential and light commercial plumbing. Buyers should confirm the exact gasket material with the supplier based on their system's fluid compatibility.

Plumbing contractors, building material distributors, and mechanical engineers specify these couplings for joining hubless cast iron pipe in multi-story buildings, hospitals, and schools where noise attenuation and fire resistance of cast iron are required. Richang Qiaoshan Trade, based in Beijing, supplies these in cartons of 100 pieces with loading at the port of Xingang, China. The supplier has manufactured cast iron soil pipe systems since 1996, and buyers can request their full product catalog for compatible pipes and fittings.
