Ductile Iron Couplings

Introducing Ductile Iron Couplings - the perfect solution for restraining HDPE pipes in water supply, drainage, sewage, and other applications. These couplings come equipped with a load-resistant mechanism that securely grips and seals the HDPE pipe, preventing it from slipping off the pipeline system. With a maximum working temperature of 80℃, this coupling is suitable for a wide range of applications.

Featuring a unique sealing gasket design,This product come standard with EPDM gaskets, which are perfect for water applications. These gaskets also work for natural gas, petroleum products, drainage, and sewage pipeline systems. What's more, our couplings boast superior corrosion and damage resistance, thanks to their epoxy resin coating. This coating provides long-term protection, preventing corrosion, impact, and wear, ensuring sustained and reliable performance.

The product is also equipped with unique load-bearing copper teeth. To use, simply tighten the bolts, and the copper teeth will press against the gasket until the end ring makes contact with the sleeve. The copper teeth will then begin to reduce their diameter, and their sharp profile will cut into the PE/HDPE pipe. Once the bolts are tightened, the coupling and adapter are ready to use.

So, if you're looking for a reliable, easy-to-use product to restrain your PE/HDPE pipes in any pipeline system, look no further than our Ductile Iron Couplings. With their exceptional sealing, corrosion resistance, and damage resistance, these couplings will prove themselves essential for any water supply, drainage, sewage, or other application.
