  • Central body and lugs: High-strength GGG-50 ductile iron.
  • Sealing gasket: Adaptable-profile EPDM rubber for a tight seal.
  • Bolts: High-strength zinc-plated steel, grade 8.8.
  • Key functionality: Allows a transition (step) coupling between two different diameter ranges.
  • Universal compatibility: Suitable for a wide variety of rigid materials (PVC, PE, cast iron, steel, etc.).
  • Flexibility: Accommodates slight angular deflection, making assembly easier on misaligned pipes.
  • Assembly type: Non-restrained. Requires anchoring systems to counteract axial forces.
