Unit price perEstimated delivery between November 01 and November 03.
The 315mm Galvanised Steel Tee Piece is a rigid round ducting fitting designed to create a 90-degree branch in 315mm ventilation and air-extraction systems.
A tee piece allows one main duct run to be divided into two directions or two duct runs to be connected into a common line. Its three 315mm circular connections make it particularly useful when building larger extraction, intake and air-distribution systems.
Manufactured from galvanised steel, the fitting provides a strong and durable alternative to improvised flexible-duct junctions. The rigid construction helps maintain the shape of the airflow path while providing secure connection points for compatible 315mm ducting and ventilation components.
The large 315mm diameter makes this fitting particularly suited to high-airflow ventilation installations, including commercial horticulture, larger grow rooms, warehouses, workshops and other environments using 315mm round ductwork.
Why choose a 315mm galvanised tee piece?
- 315mm diameter - designed for compatible 315mm round ventilation systems.
- Three-way connection - creates a branch or junction within a ducting installation.
- 90-degree branch - useful for directing airflow into or out of a secondary duct run.
- Galvanised steel construction - strong, rigid and suitable for permanent ventilation installations.
- High-airflow applications - 315mm ducting is commonly used where substantial volumes of air need to be moved.
- Rigid connection points - provides a stable junction for connecting compatible ducting.
- Suitable for extraction or intake - can be incorporated into supply-air and exhaust-air systems.
- Professional installation - creates a cleaner and more durable junction than simply joining sections of flexible duct together.
- Compatible with ventilation accessories - useful alongside 315mm fans, silencers, filters, reducers, bends and ducting.
What is a ventilation tee piece used for?
A tee piece creates a three-way junction within a ventilation system. Air can travel along the main straight section while the perpendicular connection creates an additional branch.
Depending on the system design and direction of airflow, this can be used to divide one airflow into two duct runs or bring airflow from separate branches into a common duct.
This makes tee pieces useful when one extraction system needs to serve multiple areas, when air needs to be distributed to different locations or when several ventilation components need to connect into a larger duct network.
315mm ducting for grow rooms & horticulture
Larger indoor growing environments can require substantial airflow to remove heat, manage humidity and maintain effective air exchange. A 315mm ducting system provides considerably more cross-sectional area than smaller domestic-style duct sizes, making it suitable for high-capacity ventilation installations.
The 315mm tee can be used when dividing an extraction line between different sections of a grow room, combining suitable duct runs or constructing a more complex air-distribution system.
When designing a branched ventilation system, remember that airflow will not necessarily divide equally between branches. Duct length, bends, filters, silencers, restrictions and pressure differences all affect the final airflow through each route.
Why use rigid galvanised steel duct fittings?
Flexible ducting is convenient for connecting equipment and negotiating awkward spaces, but rigid fittings provide much greater structural stability at junctions and direction changes.
A galvanised steel tee maintains its shape under normal ventilation-system pressure and provides defined connection points for the three duct runs.
Combining rigid fittings with carefully installed ducting can also produce a tidier, more professional ventilation installation.
Installing a 315mm ducting tee
Plan the duct route before installation and determine whether the tee is being used to divide or combine airflow. Position the fitting so the connected duct runs can reach each opening without unnecessary bends or compression.
Connect compatible 315mm ducting or fittings to each connection and secure them using an appropriate method for the type of duct being installed. Flexible ducting is commonly secured with suitable duct clips or clamps, while rigid systems may use appropriate connectors and sealing methods.
For installations where air leakage needs to be minimised, seal the joints using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Plan branch airflow carefully
Adding a tee changes the resistance and pressure characteristics of a ventilation system. If one branch is considerably shorter or less restrictive than another, more air may naturally travel through that route.
Where controlled airflow distribution is important, the system may require suitable dampers or other balancing components.
Fans should also be selected according to the total resistance of the completed duct system rather than duct diameter alone. Carbon filters, silencers, long duct runs and multiple fittings can all reduce delivered airflow.
Compatible 315mm ventilation equipment
This tee piece can form part of a complete 315mm round ventilation system and can be used alongside appropriately sized equipment such as:
- 315mm rigid or flexible ventilation ducting
- 315mm inline extraction fans
- 315mm carbon filters
- 315mm acoustic silencers
- 315mm duct bends and elbows
- 315mm reducers and enlargers
- 315mm connectors and couplers
- Suitable duct clamps, clips and sealing materials
Always check the actual connection dimensions and fitting method of adjoining components before installation.

315mm Galvanised Tee Piece FAQs
What size ducting fits this tee piece?
The fitting is designed for nominal 315mm round ventilation systems. Always check the connection method and actual dimensions of adjoining equipment before installation.
Is the branch at 90 degrees?
Yes. The side branch is positioned perpendicular to the main straight duct path, creating a conventional tee configuration.
What is the tee piece made from?
It is manufactured from galvanised steel, providing a strong and rigid fitting for ventilation installations.
Can I connect flexible ducting to it?
Yes, compatible 315mm flexible ventilation ducting can be connected and secured using suitable clamps or clips, subject to the dimensions and construction of the duct being used.
Can it be used with rigid ducting?
Yes. It is designed as a rigid ventilation fitting and can be incorporated into compatible 315mm rigid duct systems using the appropriate connection method.
Can I use this tee on an extraction system?
Yes. It can be used to divide or combine duct routes within a correctly designed extraction system.
Can it be used for intake ventilation?
Yes. The same fitting can be used in suitable air-supply and intake duct systems.
Will airflow split equally through both branches?
Not necessarily. Airflow distribution depends on the resistance of each duct route, including its length, bends, filters, silencers and other restrictions.
Do I need to seal the duct connections?
Where minimising air leakage is important, joints should be secured and sealed using suitable ventilation-system clamps, foil tape or another appropriate method.
Can I use this with a 315mm carbon filter?
It can form part of a ventilation system containing a 315mm carbon filter, provided the overall system is correctly designed and the adjoining components are dimensionally compatible.
Can I use a tee to connect two grow-room extraction points?
Yes, a tee can be used to combine suitable duct runs, but the fan capacity, pressure losses and airflow balance of the complete system should be considered.
Is 315mm ducting suitable for high-airflow systems?
315mm is a relatively large ventilation duct diameter and is commonly selected for systems designed to move substantial volumes of air. Actual airflow depends on the fan and resistance of the complete installation.
Do I need a damper with a tee piece?
Not always. However, dampers can be useful where airflow needs to be balanced between branches rather than allowing it to divide according to the natural resistance of each duct route.
