Description
The
160mm double socket T branch is a genuine Funke underground drainage fitting designed to introduce an equal 160mm branch into a compatible 160mm main drainage run. This
Funke KGEA drainage branch provides a durable
160mm underground drainage branch with an official manufacturer angle of 87°, creating an
87 degree drainage branch and practical
160mm equal T junction for foul-water and surface-water systems. Commonly described in the trade as a 90° T branch, Funke identifies the exact fitting as
KGEA DN 160/160/87° SDR 41. It is a double-socket PVC-U branch certified to BS EN 1401-1 for non-pressure underground drainage and sewerage.
160mm Double Socket T Branch
The
160mm double socket T branch is designed for compatible underground drainage systems where the main run and side branch are all nominal 160mm. The equal configuration makes it suitable for larger drainage layouts where an additional full-size 160mm pipe needs to connect into the main system.
Choosing a 160mm Double Socket T Branch
Choose the
160mm double socket T branch where a near-right-angle connection is required and the branch pipe is the same nominal size as the 160mm main drainage run. If the incoming branch is 110mm, use a 160mm-to-110mm unequal branch instead.
Funke KGEA Drainage Branch
The
Funke KGEA drainage branch is part of Funke’s PVC-U underground drainage fitting range. BSI identifies this exact model as
KGEA DN 160/160/87° SDR 41, with a DN160 equal branch, 87° angle, double-socket configuration and orange-brown finish.

160mm Underground Drainage Branch
This
160mm underground drainage branch provides an equal connection for larger below-ground gravity drainage systems. It can form part of compatible foul-water, wastewater, surface-water and rainwater drainage layouts where DN160 pipework is specified.
160mm Underground Drainage Branch Applications
The
160mm underground drainage branch can be used in suitable applications including:
- 160mm foul-water drainage systems
- Surface-water drainage
- Rainwater drainage systems
- Larger domestic drainage installations
- Commercial groundworks
- Drainage extensions and alterations
- Main underground drainage runs
87 Degree Drainage Branch
Although commonly referred to as a 90° branch in trade terminology, Funke officially specifies this fitting as an
87 degree drainage branch. The near-right-angle geometry provides the familiar T-branch arrangement while retaining the manufacturer’s certified specification.
87 Degree Drainage Branch vs 90 Degree Trade Description
The terms 87° and 90° are often used around near-right-angle underground drainage fittings, but the exact
87 degree drainage branch designation should be retained in the technical specification. For customer search and recognition, the product can still be described as a 90° T branch while clearly recording Funke’s official 87° angle.
160mm Equal T Junction
The fitting creates a
160mm equal T junction because all three drainage connections use the same nominal DN160 pipe size. A
160mm equal T junction is useful where a full-size branch line needs to enter a larger underground drainage network without reducing the branch diameter.
Equal T Junction vs Unequal Branch
An equal junction uses the same nominal size throughout the fitting. An unequal junction uses a smaller branch connection, such as 110mm entering a 160mm main run.
Double Socket Connection
The branch uses a double-socket configuration for compatible push-fit drainage connections. Socketed connections use sealing rings to create secure joints with compatible PVC-U pipe or fitting spigots.
Installing the Double Socket Branch
Before assembly, check the sockets, seals and adjoining pipe surfaces are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert prepared pipe or fitting spigots squarely into the sockets without displacing the seals.
PVC-U Underground Drainage
The Funke branch is manufactured from PVC-U for non-pressure underground drainage and sewerage systems. PVC-U provides a lightweight, corrosion-resistant pipe system widely used for foul-water and surface-water drainage.
BS EN 1401-1 Certified Fitting
The exact Funke fitting is independently listed by BSI under certificate KM 45958 to
BS EN 1401-1. The BSI record identifies the model as
KGEA DN 160/160/87° SDR 41, DN160, 87° branch, double socket and orange-brown.
Standard Branch vs Swept Branch
This product is the standard KGEA branch and should not be confused with Funke’s separate swept version. Funke’s swept DN160 branch carries the separate designation
KGEA-S DN 160/160/87° SDR 41. If the fitting is specifically described or marked as swept, that alternative model should be selected instead.
Double Socket vs Triple Socket Branch
A double-socket branch has a different connection arrangement from a triple-socket version. Funke also manufactures a separate triple-socket swept branch, identified as KGEA-S-TS. This listing is specifically for the standard double-socket fitting.
