Unit price perEstimated delivery between November 01 and November 03.
The 250mm Galvanised Steel Tee Piece is a rigid round ducting fitting designed to create a 90-degree branch within 250mm ventilation, extraction and air-distribution systems.
Featuring three 250mm circular connections, this tee fitting provides a straightforward way to divide a main duct run into two routes or combine separate duct runs into a common ventilation line.
Its galvanised steel construction provides a strong, rigid junction for permanent and semi-permanent ventilation installations. Compared with trying to create a branch using flexible ducting alone, a purpose-made metal tee maintains a defined airflow path and provides secure connection points for adjoining ductwork.
The 250mm diameter makes this fitting well suited to medium and high-airflow ventilation systems used in grow rooms, commercial horticulture, workshops, warehouses and other indoor environments.
Why choose a 250mm galvanised tee piece?
- 250mm diameter - designed for compatible 250mm round ventilation systems.
- Three-way duct connection - creates a practical branch or junction within a ventilation system.
- 90-degree branch - the side connection runs perpendicular to the main duct path.
- Galvanised steel construction - strong and rigid for dependable ventilation installations.
- Suitable for extraction and intake - can be incorporated into exhaust-air or supply-air duct systems.
- Rigid connection points - provides a stable junction for connecting compatible ductwork.
- Useful for larger ventilation systems - 250mm ducting is commonly selected where substantial airflow is required.
- Professional duct installation - creates a cleaner junction than improvising branches from flexible ducting.
- Compatible with 250mm ventilation equipment - useful alongside fans, carbon filters, silencers, bends, reducers and ducting.
What is a 250mm ducting tee used for?
A ventilation tee creates a three-way junction in a round ducting system. The straight section continues the main duct route while the side connection creates an additional 90-degree branch.
Depending on the direction of airflow and system design, the tee can be used to divide airflow between two duct runs or combine airflow from separate branches into one main duct.
This makes it useful for multi-zone extraction systems, air-distribution installations and ventilation layouts where several components or areas need to connect to a shared duct run.
250mm ducting for grow rooms & horticulture
Environmental control in larger indoor growing spaces often requires substantial airflow to remove excess heat and humidity while maintaining regular air exchange.
A 250mm ventilation system can accommodate considerably more airflow than smaller duct sizes when matched with appropriately sized fans and other equipment.
This tee piece can be used to create separate extraction or intake branches, combine suitable duct runs or build a more comprehensive ventilation network serving different parts of a growing area.
When branching a system, remember that airflow will not automatically divide equally. The length and resistance of each branch will influence how much air travels through it.
Rigid galvanised steel construction
Flexible ventilation ducting is useful for connecting equipment and routing air through difficult spaces, but junctions benefit from the additional stability provided by rigid fittings.
The galvanised steel construction allows the tee to retain its shape while providing defined circular connections for adjoining ductwork.
This makes it suitable for creating a tidy, robust and professional ventilation installation, particularly where ducting may need to be supported over longer distances.
Installing a 250mm ventilation tee
Plan the complete duct route before installation and decide whether the tee will divide one airflow into two branches or combine separate branches into a single line.
Connect compatible 250mm ducting or ventilation fittings to each opening and secure them using a suitable connection method. Flexible ducting can typically be secured using appropriately sized duct clips or clamps.
Where air leakage needs to be minimised, joints can also be sealed using suitable HVAC foil tape or another appropriate ventilation-system sealing product.
Support the surrounding ductwork correctly so that excessive weight is not transferred to the tee or adjoining equipment.
Understanding airflow through a tee junction
Installing a tee changes the pressure characteristics of a ventilation system. Air naturally follows the route offering the least resistance, so two branches connected to the same tee may carry different amounts of air.
A short, straight branch will generally present less resistance than a longer route containing several bends, a filter or other restrictive components.
Where airflow needs to be distributed accurately between different branches, suitable balancing dampers or other airflow-control components may be required.
Designing an efficient 250mm ventilation system
Duct diameter is only one part of ventilation-system design. The actual airflow delivered by a fan is affected by the total resistance of the complete installation.
Carbon filters, silencers, long duct runs, tight bends, reducers and junctions all introduce resistance. Keeping duct routes as short and direct as practical can help reduce unnecessary pressure losses.
When several branches are being connected to one extraction fan, ensure that the fan has sufficient capacity for the complete system rather than sizing it for an individual duct run.
Compatible 250mm ventilation equipment
The tee piece can form part of a complete 250mm round ventilation system and can be used alongside appropriately sized equipment including:
- 250mm flexible ventilation ducting
- 250mm rigid ducting
- 250mm inline extraction fans
- 250mm carbon filters
- 250mm acoustic silencers
- 250mm duct bends and elbows
- 250mm reducers and enlargers
- 250mm connectors and couplers
- Suitable duct clips, clamps and sealing materials
Always check the actual connection dimensions and fitting method of adjoining equipment before installation.

250mm Galvanised Tee Piece FAQs
What size ducting fits this tee piece?
It is designed for nominal 250mm round ventilation systems. Check the dimensions and connection style of adjoining equipment before installation.
Is the side branch at 90 degrees?
Yes. The branch is positioned perpendicular to the main straight duct path to form a conventional tee junction.
What is the tee piece made from?
It is manufactured from galvanised steel, providing a strong and rigid fitting for ventilation ductwork.
Can I connect 250mm flexible ducting to it?
Yes. Compatible 250mm flexible ducting can be connected and secured using appropriately sized duct clips or clamps.
Can it be used with rigid ventilation ducting?
Yes. The tee can form part of a compatible rigid 250mm round ducting system using the appropriate connectors and installation method.
Can a 250mm tee be used for extraction?
Yes. It can be incorporated into a correctly designed extraction system to divide or combine duct routes.
Can it be used for intake ventilation?
Yes. The fitting can also be used in suitable air-intake and supply-air systems.
Will airflow divide equally through both branches?
Not necessarily. Airflow through each branch depends on its resistance, including duct length, bends, filters, silencers and other components.
Can I use a damper with the tee?
Yes. Dampers can be useful where airflow needs to be balanced between different branches of a ventilation system.
Should the duct joints be sealed?
Where minimising air leakage is important, joints should be secured and sealed using suitable ventilation clamps, HVAC foil tape or another appropriate method.
Can this be used with a 250mm carbon filter?
Yes. It can form part of a system containing a 250mm carbon filter, provided the complete ventilation system is correctly sized and the adjoining connections are compatible.
Can one extraction fan serve two duct branches?
Potentially, yes. The fan must have sufficient capacity to overcome the combined resistance of the complete system, and airflow may need to be balanced between the branches.
Is 250mm ducting suitable for high-airflow grow rooms?
250mm is a substantial ventilation duct size commonly used in medium and high-airflow systems. Actual airflow capacity depends on the fan, duct layout and resistance of the complete installation.
