The 6 inch flexible rubber coupling is a no-hub mechanical joint component designed for connecting cast iron soil pipes and fittings in drainage systems. This coupling features a corrosion-resistant rubber sleeve with stainless steel clamping bands, accommodating pipe sizes up to 6 inches in diameter. It is engineered to absorb vibration, compensate for minor misalignment, and provide a watertight seal in non-pressure applications.
Manufactured from EPDM or neoprene rubber compounds, the coupling offers flexibility and durability in both residential and commercial plumbing installations. Typical operating temperature ranges from -40°C to 100°C, with a standard pressure rating of 0.1 MPa for non-pressure systems. The rubber material is reinforced with nylon cord for added strength, and the stainless steel bands are typically A2-70 grade for corrosion resistance.
This coupling is primarily used in sanitary and storm drainage systems, connecting sections of cast iron pipe where rigid joints are impractical. Contractors and plumbing suppliers source these components for new construction and retrofit projects. Packaging is 50 pieces per carton, with the port of loading specified as Xingang, China. The supplier has produced cast iron pipe fittings and couplings since 1996, specialising in drainage system components.

Before ordering, verify that the 6 inch flexible rubber coupling meets the specific standards required for your drainage system, such as ASTM C1277 for no-hub couplings. Check the compatibility of the rubber material with the fluids and temperatures in your application, as EPDM and neoprene have different chemical resistance profiles.
Confirm the logistics details, including the port of loading at Xingang, China, and the packaging quantity of 50 pieces per carton. Discuss Incoterms such as FOB or CIF with the supplier to clarify responsibilities for shipping, insurance, and customs clearance. Lead times may vary, so request a production schedule for bulk orders.
Inspect the couplings upon arrival for defects in the rubber sleeve and clamping bands, as these components must be free of cracks or deformation. Request a material test report to confirm the grade of stainless steel and rubber composition. Ensure all documentation, including packing lists and certificates of compliance, is provided for customs and quality assurance purposes.
