Frequently Asked Questions (FAQ)
Our couplings are UPC listed, CSA certified, and fully compliant with the ASTM A888 standard, making them ideal for North American building drainage and sewage systems.
The outer shield and bands are constructed from high-grade 304 stainless steel. The inner gasket is made of multi-layer EPDM or chloroprene rubber, reinforced with an orange or blue layer for enhanced sealing and anti-aging performance.
Yes, our No Hub Couplings are designed for W-type hubless cast iron drainage pipes and can also serve as reliable transition joints between cast iron pipes and PVC DWV pipes.
We supply a complete range of standard sizes from DN50 up to DN300. Custom thickness and strap widths can also be manufactured to suit your project specifications.
The flexible joint design allows for 3° to 5° of angular deflection and effectively compensates for thermal expansion and contraction, reducing stress on the pipeline.
Yes, we support and welcome third-party inspections before shipment, as required by the customer, to guarantee consistent quality.
