We are an professional manufacturer and supplier for flexible coupling, from sizes of 1-1/4” to 18”. The CUPC Approved Flexible Reducer Couplings are well sold in USA and Canada. Our Couplings have earned a reputation for consistent, superior performance, giving you full confidence in their quality and reliability. The dimensional flexibility of our flexibel couplings ensures leak-proof pipe seals on virtually any pipe material: plastic, cast iron, asbestos cement, clay, concrete, steel, copper and ductile iron. All flexible couplings are clearly marked with part number, size, and pipe material that the coupling will connect to.
Tested designs backed by over five decades of proven performance
Positive seal against infiltration and exfiltration
Leak-proof and is resistant to chemicals, ultraviolet rays,
fungus growth, and normal sewer gases
Conforms to ASTM D 5926, C 1173 and CSA B602
Connects same or different pipe sizes and materials quickly and easily
Stainless steel clamps are corrosion-resistant and rustproof
Our CUPC Approved Flexible Reducer Couplings(flexible pipe adapters)are used by professionals nationwide. The high quality pipe adapters are made of tough elastomeric polyvinyl chloride, they are strong, resilient and unaffected by soil conditions. They are also resistant to chemicals, ultraviolet rays, and fungus growth due to the specially formulated properties of the material. These flexible pipe adapters are supplied with a 300 series stainless steel clamp, which is corrosion resistant and rustproof. Additional band slots have been added for greater flexibility and the clamps are specially designed for greater sealing efficiency. These couplings adapt to different types of pipe, clay to cast iron or plastic. Install using a torque wrench to ensure a water tight connection.
