Seamlessly Connect Pipes of Different Diameters The Cascade Step Coupling is an essential problem-solver designed to join two pipes with significantly different Outer Diameters (ODs). Whether connecting old imperial steel pipes to new metric PVC, or AC to Ductile Iron, this coupling ensures a leak-free transition.
Half Couplings for creating secure, leak-proof branch connections or outlets from pipelines and vessels. Our fittings ensure lasting integrity for your piping system.
Product Overview Cascade Long Barrel Couplings are specifically designed for the reliable connection of GRP (Glass Reinforced Plastic) and HDPE (High-Density Polyethylene) pipelines. The extended barrel length is engineered to accommodate thermal expansion and contraction during and after installation, ensuring long-term joint integrity.
Wide range couplings suitable for joining pipes with the same nominal diameter – which have the same or different OD’s. Cast in ductile iron Grade 420/12 to BS 2789:1985. PE coated to: - provide maximum corrosion protection - prevent chipping or gouging of the coating Rubber seals are approved for potable water and are certified to “WRAS/BS6920”. Large diameter bolts…
