Our stainless steel and rubber reducing couplings are engineered for superior performance in soil pipe applications. These high-quality connectors feature a durable stainless steel body with precision rubber seals, designed to create leak-proof connections between pipes of varying diameters.

These couplings are particularly suitable for HDPE hollow wall winding pipes and find extensive applications in:
- Municipal drainage systems for urban road and rainwater management
- Building drainage networks for residential and commercial complexes
- Agricultural irrigation and water transportation systems
- Industrial wastewater discharge in factory and mining operations
- Road construction projects including bridge and culvert drainage

The product combines the strength of stainless steel with the flexibility of rubber, offering excellent resistance to corrosion, wear, and aging. Compared to traditional materials like cement or cast iron, our couplings provide easier installation and longer service life.
Available in standard sizes from 2" (DN50) to 6" (DN150), we also accommodate custom sizing requirements. The couplings can be manufactured using either 304 or 316 grade stainless steel with natural rubber or EPDM sealing components based on application needs.

Our manufacturing process includes strict quality control at every stage, from material inspection to final packaging. Each coupling undergoes dimensional verification and visual inspection to ensure perfect fit and finish.
For bulk purchasers and project contractors, we offer competitive wholesale pricing with flexible order quantities. OEM services including custom branding and packaging are available for qualified orders.
