Key Features & Benefits

  • Optimized Flow Dynamics: The 87.5° sweeping long radius ensures exceptionally smooth waste transitions, lowering the risk of backflow or sediment build-up compared to standard short bends.

  • Advanced Captive Lip Seal: Specially engineered combined lip and compression seals guarantee a water-tight fit that stays locked in place during pipe insertion, entirely eliminating seal displacement.

  • Two-Way "Rest" Design: Built structurally to handle load-bearing transitions, making it ideal for support at the bottom of a vertical vertical drop before moving to horizontal underground lines.

  • Exceptional Durability: Manufactured in the UK from high-grade, impact-resistant PVC-U to resist ground movement, thermal changes, and soil chemicals.

  • Full Compliance: Kitemarked and fully certified to BS EN 1401-1 and manufactured under ISO 9001:2015 quality management.
