6" Heavy Duty No Hub Coupling
This 6 inch heavy duty no hub coupling is designed for C.I. (cast iron) pipe connections and is manufactured by Richang Qiaoshan Trade Co. Ltd. from China. The coupling uses 300 series stainless steel for the clamp and EPDM or neoprene for the sealing gasket, ensuring durability and resistance to corrosion and chemicals. It is packed 40 pieces per carton and shipped from Xingang port.
No hub couplings are used to join plain-end pipes without the need for hubs or flanges, providing a leak-proof and secure connection. The 300 series stainless steel is a standard choice for such couplings due to its high tensile strength and resistance to rust, while EPDM/neoprene gaskets offer excellent sealing properties for plumbing and drainage systems. Typical pressure ratings for these couplings range from 10 to 15 psi, depending on the application.
This product is primarily used in commercial and residential plumbing, drainage, and HVAC systems where cast iron pipes are installed. Contractors and plumbing suppliers source these couplings for repairs, extensions, or new installations. Buyers should confirm the exact pressure rating, temperature range, and compatibility with their pipe material before ordering.

Sourcing 6" Heavy Duty No Hub Coupling from Richang Qiaoshan Trade Co. Ltd. - China Import Guide
Before placing an order, verify the coupling's pressure rating, temperature range, and compatibility with your pipe material (cast iron). Request samples for testing, especially if the coupling will be used in high-pressure or high-temperature applications.
Confirm logistics details such as lead time, port of loading (Xingang), and Incoterms (e.g., FOB, CIF) with the supplier. Discuss packaging options, as the listing specifies 40 pieces per carton, and ensure it meets your handling and storage requirements.
Request quality documentation, including material certificates for the 300 series stainless steel and EPDM/neoprene gaskets. Inspect a sample batch for defects like uneven clamping surfaces or gasket imperfections. Ensure the supplier provides a packing list and test reports for pressure and leak resistance.
