Description
The
TetraFlow RT6 tee branch is a genuine 160mm underground drainage fitting designed to create a near-right-angle branch connection within compatible below-ground drainage pipework. This
160mm triple socket tee branch provides socketed connections for a practical
160mm underground drainage branch. Commonly described in the trade as a
90 degree drainage tee, TetraFlow officially specifies the RT6 as an 88° equal sweep branch, providing the flowing profile of a
160mm swept drainage branch. TetraFlow lists manufacturer code
RT6 for the 160mm equal sweep branch. The manufacturer gives dimensions of 160mm diameter, 354mm overall height and 178mm branch length.
TetraFlow RT6 Tee Branch
The
TetraFlow RT6 tee branch is designed for compatible 160mm underground drainage systems where an additional pipe run needs to join the main drainage line at a near-right-angle connection. Its equal configuration means the main run and branch connections are all nominal 160mm.
Choosing the TetraFlow RT6 Tee Branch
Choose the
TetraFlow RT6 tee branch where the drainage layout requires a genuine TetraFlow 160mm equal sweep branch. TetraFlow officially specifies the fitting at 88°, although near-right-angle underground drainage branches of this type are commonly described as 90° tee branches in trade terminology.
160mm Triple Socket Tee Branch
The
160mm triple socket tee branch provides socketed connections for joining compatible underground drainage pipework. The triple-socket configuration allows compatible plain-ended pipe to connect directly into both sides of the main drainage run and into the branch connection.
Installing a 160mm Triple Socket Tee Branch
Before fitting the
160mm triple socket tee branch, check that the sockets, sealing rings and adjoining pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert prepared pipe ends squarely into each socket without displacing the seals.
160mm Underground Drainage Branch
The
160mm underground drainage branch allows an additional 160mm pipe run to connect into a compatible main drainage line. It can form part of suitable foul-water, surface-water and rainwater drainage systems across domestic, commercial and groundwork installations.
160mm Underground Drainage Branch Applications
The
160mm underground drainage branch can be used for suitable applications including:
- 160mm foul-water drainage
- Surface-water drainage
- Rainwater drainage systems
- Commercial groundworks
- Larger domestic drainage systems
- Drainage extensions
- Property drainage connections
- Drainage repairs and alterations
90 Degree Drainage Tee
The fitting is commonly described as a
90 degree drainage tee because it creates a near-right-angle branch connection. TetraFlow’s manufacturer specification identifies the RT6 more precisely as an
88° equal sweep branch.
Using a 90 Degree Drainage Tee
When positioning a
90 degree drainage tee, consider the direction of flow, drainage falls and future inspection or rodding access. The branch and surrounding pipework should be correctly supported and bedded before backfilling.
160mm Swept Drainage Branch
The RT6 uses the profile of a
160mm swept drainage branch, helping provide a smoother transition into the main drainage run than a compact square junction. A
160mm swept drainage branch can be particularly useful on larger gravity drainage systems where flow direction and maintenance access are important considerations.
Benefits of a 160mm Swept Drainage Branch
- Near-right-angle branch connection
- Equal 160mm connections
- Swept junction profile
- Push-fit underground drainage connection
- Suitable for larger drainage runs
- Suitable for compatible foul-water and surface-water systems
TetraFlow RT6 Manufacturer Dimensions
TetraFlow publishes the following dimensions for the standard RT6 equal sweep branch:
- Manufacturer code: RT6
- Nominal size: 160mm
- Manufacturer angle: 88°
- D: 160mm
- H: 354mm
- L: 178mm
Equal Branch vs Unequal Branch
This is an equal branch, meaning the main drainage run and side branch use the same nominal 160mm pipe size. If a 110mm branch needs to connect into a 160mm main run, choose a 160mm to 110mm unequal branch instead.
90° Tee vs 45° Y Branch
A near-90° tee introduces the connecting pipe at a steeper angle than a 45° Y branch. The correct fitting depends on the drainage route, direction of flow, available space and installation design.
