Product Overview

160mm x 110mm unequal junction with a double socket design and a 45-degree entry to link a smaller 110mm branch into a 160mm drainage run. Manufactured to BS EN 1401-1 standards, it ensures durable, watertight connections in underground foul and surface water networks.


The unequal design enables different pipe diameters to integrate within a single drainage layout, making it a practical solution for systems where a 110mm line must feed into a larger 160mm run.


With a shallow 45-degree branch angle, the fitting reduces flow turbulence and helps maintain hydraulic efficiency across the system. Its double socket ends allow direct push-fit connection of plain-ended pipes without the need for separate couplers.

Features & Benefits

  • Durable uPVC body: Resistant to corrosion, chemicals, and long-term ground exposure.
  • Equal compatibility: Connects a 160mm main pipe with a 110mm branch for mixed-size layouts.
  • Watertight seals: Integrated push-fit sockets with rubber gaskets provide reliable joints.
  • Lightweight handling: Easy to position, cut, and install with standard tools.
  • Double socket design: Allows direct connection of plain-ended pipes without extra fittings.
  • 45-degree branch entry: Ensures a smoother transition than sharper junctions, reducing blockages.


Applications

  • Size transition: Links 110mm branch pipework into a 160mm main drainage run.
  • Foul water drainage: Suitable for connecting domestic or commercial sewer pipes.
  • Surface water management: Integrates rainwater or stormwater pipes into larger networks.
  • System expansion: Adds new branch connections to existing 160mm underground layouts.
  • Hydraulic efficiency: Maintains smoother flow by diverting at a shallow angle.


Installation Guidance

  • Preparation: Cut and chamfer pipe ends, ensuring smooth edges before jointing.
  • Connection: Push plain-ended 110mm and 160mm pipes fully into the sockets until seated.
  • Seal protection: Avoid twisting or damaging the rubber seals during insertion.
  • Bedding: Place on a suitable granular bed for support and stability.
  • Backfilling: Surround with compacted granular material before final backfill.


Compliance & Performance

  • Standard: Manufactured to BS EN 1401-1.
  • Size: 160mm x 110mm, 45-degree angle.
  • Type: Unequal junction, double socket.
  • Material: Unplasticised PVC (uPVC).
  • Applications: Underground foul and surface water systems.
  • Performance: Provides secure, watertight size transition with minimal flow disruption.
  • Durability: Resistant to corrosion, ground chemicals, and long-term burial conditions.
