Step Coupling
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.
Description
Key Features:
- Diameter Adaptability: Engineered with “stepped” end rings to match two different pipe sizes.
- Multi-Material Joining: Perfect for transitioning between materials (e.g., Steel to PVC).
- Pressure Tight Seal: Independent bolting on each end to ensure a secure grip on both pipe sizes.
