Description
Blumat Tee 8mm x 3mm – Tropf-Blumat Irrigation T-Piece
The Blumat Tee 8mm x 3mm, also known as the Blumat T-Piece 8-3-8mm, is an essential irrigation fitting designed to connect a Tropf-Blumat or Tropf-Blumat Maxi watering sensor to the main 8mm feeding tube.
The fitting installs directly inline with the 8mm supply tubing while providing a 3mm outlet for the drip tube leading to the Blumat sensor. This allows individual watering points to be positioned along the main irrigation line without interrupting water flow to the rest of the system.
Ideal as a replacement fitting or for expanding a custom Blumat irrigation network, the 8mm x 3mm Tee provides a simple and reliable way to add additional sensors and watering zones.

What Does the Blumat 8mm x 3mm Tee Do?
The T-piece provides a connection point between the main 8mm irrigation supply line and the smaller 3mm tubing used to supply a Tropf-Blumat sensor.
The fitting has three connections:
8mm Inlet → 3mm Sensor Outlet → 8mm Outlet
This means the main water supply can continue along the 8mm line while a smaller branch supplies an individual Tropf-Blumat.
A typical installation looks like:
8mm Feeding Tube → 8-3-8mm Tee → 8mm Feeding Tube

3mm Drip Tube

Tropf-Blumat Sensor
This simple arrangement makes it possible to position multiple Tropf-Blumat sensors along one main feeding line.
Designed for Tropf-Blumat Sensors
The T-Piece 8-3-8mm is the type of fitting supplied with Tropf-Blumat watering sensors.
Its purpose is to connect the sensor's 3mm drip tube to the larger 8mm feeding tube running through the garden.
It can therefore be useful when:
- Replacing a lost fitting
- Replacing a damaged fitting
- Reconfiguring an irrigation system
- Moving sensors to new locations
- Building a custom Blumat setup
- Adding additional watering points
8mm Main Line with 3mm Sensor Connection
Blumat irrigation systems use different tubing sizes for different purposes.
8mm Feeding Tube
The 8mm tubing acts as the main water supply line, carrying water from the reservoir, tank connector or appropriately regulated water source around the growing area.
3mm Drip Tube
The 3mm tubing provides the smaller connection to the Tropf-Blumat sensor and compatible distribution components.
The Blumat Tee provides the transition between these two parts of the irrigation system without terminating the main 8mm line.
Perfect for Adding Sensors Along an 8mm Supply Line
The Tee is particularly useful when several plants are positioned along the same irrigation route.
Instead of terminating and restarting the main supply line at each plant, the 8mm tubing can continue throughout the garden.
At each required sensor location:
8mm Line → Tee → 8mm Line Continues
with the:
3mm Outlet → Tropf-Blumat Sensor
This creates a clean and expandable irrigation network.
Compatible with Tropf-Blumat Maxi
The fitting can also be used to connect a Tropf-Blumat Maxi sensor to the main 8mm feeding tube.
Tropf-Blumat Maxi sensors are designed for applications where moisture needs to be monitored deeper within larger containers or growing areas.
The same basic connection principle applies:
8mm Supply → 8-3-8mm Tee → 3mm Tube → Tropf-Blumat Maxi
Suitable for Blumat 8mm Superflex Tubing
The Tee can be paired with compatible Blumat 8mm Superflex Tubing to create an especially flexible irrigation network.
Superflex tubing can make it easier to route the main supply around:
- Plant containers
- Fabric pots
- Raised beds
- Grow tent poles
- Greenhouse benches
- Living soil beds
- Other irrigation equipment
The 8-3-8mm Tee can then be installed wherever a 3mm sensor connection is required.
Easy Installation
Installing the Blumat Tee is straightforward.
Step 1 – Determine Sensor Position
Choose where the Tropf-Blumat sensor will be positioned in relation to the main 8mm feeding tube.
Step 2 – Cut the 8mm Tubing
Make a clean, square cut in the 8mm feeding tube at the required connection point.
Step 3 – Install the Tee
Push each section of 8mm tubing securely onto the corresponding 8mm connections of the T-piece.
Step 4 – Connect the 3mm Tube
Push the compatible 3mm drip tubing onto the smaller outlet.
Step 5 – Connect the Sensor
Run the 3mm tubing to the Tropf-Blumat or Tropf-Blumat Maxi according to the irrigation system configuration.
Step 6 – Test for Leaks
Turn on the water supply and inspect all connections before relying on the system for unattended irrigation.
Blumat Tee vs End-Piece
Blumat offers different fittings depending on where the sensor is positioned along the 8mm supply line.
| Fitting | Best Application |
|---|---|
| T-Piece 8-3-8mm | Connecting a sensor along an existing 8mm feeding line |
| End-Piece 8-3mm | Connecting a sensor at the end of an 8mm feeding line |
| Tee 8-8-8mm | Branching the main 8mm feeding tube |
| Mini-Tee 3-3-3mm | Branching smaller 3mm drip tubing |
When Should I Use the 8-3-8mm Tee?
Use this fitting when the 8mm main line needs to continue past the Tropf-Blumat connection.
When Should I Use an 8-3mm End-Piece?
Use an end-piece when the Tropf-Blumat connection is positioned at the end of an 8mm supply run.
This distinction can help growers select the correct fitting when building a custom irrigation system.
Build an Expandable Blumat Irrigation Network
The 8mm x 3mm Tee makes it easy to add additional sensors along a common supply line.
For example:
Water Source
↓
8mm Feeding Tube
↓
8-3-8mm Tee → 3mm → Tropf-Blumat #1
↓
8mm Feeding Tube
↓
8-3-8mm Tee → 3mm → Tropf-Blumat #2
↓
8mm Feeding Tube
↓
8-3-8mm Tee → 3mm → Tropf-Blumat #3
This modular design allows the irrigation system to be expanded as the garden develops.
Suitable for Gravity-Fed & Regulated Systems
The Tee can be used within appropriately configured gravity-fed or pressure-regulated Tropf-Blumat systems.
Gravity-Fed System
A typical gravity-fed installation may use:
Elevated Reservoir → Tank Connector → 8mm Feeding Tube → 8-3-8mm Tees → Tropf-Blumat Sensors
Pressurised System
An appropriately configured pressurised installation may use:
Water Supply → Blumat Pressure Reducer → 8mm Feeding Tube → 8-3-8mm Tees → Tropf-Blumat Sensors
The Tee itself does not regulate water pressure. The correct water-source and pressure-control equipment must be selected for the complete irrigation system.
Ideal for Living Soil Irrigation
Tropf-Blumat systems are particularly popular for living soil and no-till growing, where maintaining relatively consistent moisture throughout the root zone can support the biological activity of the growing medium.
The 8mm x 3mm Tee makes it easy to add moisture-responsive watering points around:
- Living soil beds
- Large fabric pots
- No-till containers
- Raised beds
- Organic gardens
- Greenhouses
- Indoor grow tents

Why Choose the Blumat 8mm x 3mm Tee?
The Blumat Tee 8mm x 3mm is a small but essential component when building or expanding a Tropf-Blumat irrigation system.
Its 8-3-8mm configuration allows the main 8mm feeding tube to continue through the garden while providing a dedicated 3mm connection for a Tropf-Blumat sensor.
This makes it ideal for installing multiple sensors along a single supply line, replacing damaged fittings or modifying an existing automatic watering system.
For growers building customised Blumat irrigation networks, keeping spare 8-3-8mm T-pieces on hand also makes future expansion and maintenance considerably easier.
