Description
The 160mm Y branch 45° triple socket is an underground drainage fitting used to connect a 110mm branch pipe into a larger 160mm drainage run. It is suitable for foul water and surface water drainage systems where a smaller 110mm pipe needs to join a 160mm main at an angled connection.
This Pipelife underground drainage branch has three socketed connections. The main run is designed for compatible 160mm pipework, while the 110mm branch connection allows a smaller drainage pipe to enter the system at 45 degrees.
The angled Y branch layout helps create a smoother entry into the main run compared with a 90° tee branch. As a result, it is useful on larger domestic drainage systems, commercial drainage layouts, groundwork projects and site drainage alterations.
160mm Y Branch for Underground Drainage
The 160mm Y branch is used where 110mm underground drainage pipe needs to connect into 160mm pipework. This is common where smaller drainage runs, gully lines or branch connections feed into a larger main drainage pipe.
Because the fitting has an unequal 110mm branch, it allows two pipe sizes to meet at one fitting. This helps reduce the need for extra reducers around the branch point and keeps the drainage layout cleaner.

45° Triple Socket Branch Connection
This 45° triple socket branch is designed for use with compatible underground drainage pipework. The 160mm sockets form the main pipe run, while the 110mm socket forms the smaller angled branch connection.
Before installation, check the pipe sizes, flow direction and final branch position. The branch should point in the correct direction for the drainage layout and should not be forced into poor alignment.
Use suitable pipe lubricant on ring seal joints where required. Also, make sure pipe ends are clean before jointing. If pipework is cut to length, make a clean square cut and chamfer the edge before fitting. This helps protect the seal and makes the joint easier to assemble.
160mm Y Branch Installation Use
The 160mm Y branch should be installed as part of a properly planned underground drainage system. It is useful where a 110mm pipe from a smaller branch line needs to enter a 160mm main drainage pipe at an angled connection.
Correct bedding and backfill are important around the branch. The pipework and fitting should be evenly supported so the drainage system remains stable after installation. Poor support can place stress on the sockets and may affect long-term performance.
Because this is a branch fitting, the wider drainage layout should include suitable access for future rodding, inspection or maintenance where required. Always follow the site specification, current UK drainage guidance and manufacturer instructions.
160mm Y Branch for Site Drainage Work
The 160mm Y branch is a practical fitting for builders, groundworkers, landscapers and drainage installers working with mixed 160mm and 110mm underground drainage pipework. It can be used on new drainage runs, pipework extensions, repairs and system alterations.
For best results, use compatible pipe and fittings from the same underground drainage system where possible. This helps keep jointing simple and supports a clean, consistent installation.
This fitting is not an access fitting. If inspection or rodding access is needed at this point in the drainage layout, use a suitable access branch, inspection chamber or rodding point as required.
