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.
