The 315mm Galvanised Steel Straight Connector is a rigid round duct coupler designed for joining compatible 315mm ventilation ducting and components in a straight line.
Sometimes referred to as a 315mm duct connector, coupler, joiner or male connector, this simple metal fitting provides a secure connection point between two sections of compatible round ductwork.
Its galvanised steel construction provides a strong and rigid alternative to improvised duct joints, while the compact straight-through design introduces minimal unnecessary complexity into the airflow path.
The large 315mm nominal diameter makes this connector particularly useful in high-airflow extraction and intake systems used in larger grow rooms, commercial horticulture, workshops, warehouses and other ventilation installations.
Why choose a 315mm straight duct connector?
- 315mm nominal diameter - designed for compatible 315mm round ventilation systems.
- Straight-through connection - joins two compatible duct sections without changing airflow direction.
- Galvanised steel construction - strong and rigid for dependable ventilation installations.
- Compact fitting - adds very little additional length to the duct run.
- Suitable for extraction or intake - can be incorporated into exhaust-air and supply-air systems.
- Ideal for flexible ducting - provides a solid joining point between compatible sections of 315mm flexible duct.
- Useful with rigid systems - can also form part of a compatible rigid round duct installation.
- High-airflow applications - suitable for larger ventilation installations using 315mm ductwork.
- Professional connection - creates a cleaner and more secure joint than trying to overlap ducting sections.
What is a 315mm straight duct connector used for?
A straight connector is one of the simplest components in a round ventilation system. Its purpose is to provide a connection point between two compatible sections while maintaining the same nominal duct diameter.
It is particularly useful when joining lengths of flexible ducting, extending an existing duct run or connecting compatible components where a short straight coupling is required.
Unlike a reducer, bend or tee piece, the connector does not intentionally change the duct diameter, airflow direction or number of branches.
315mm ventilation for grow rooms & horticulture
Larger indoor growing environments often require substantial ventilation capacity to remove heat and humidity and maintain regular air exchange.
A 315mm round ventilation system provides a large cross-sectional area for moving air and is commonly paired with appropriately sized extraction fans, carbon filters and silencers in high-airflow installations.
Straight connectors allow longer duct routes to be assembled from separate sections while retaining the same nominal 315mm diameter throughout the connection.
Joining 315mm flexible ducting
When joining compatible flexible ventilation duct, position the end of each duct section over the appropriate side of the connector and secure it using suitable 315mm duct clamps or clips.
Where reducing air leakage is important, the joint can additionally be sealed using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Avoid crushing or excessively deforming flexible duct around the connection, as this can reduce the effective airflow area and create unnecessary resistance.
Maintain a smooth 315mm duct run
Straight duct routes generally create less resistance than installations containing unnecessary bends, reductions and compressed flexible ducting.
A purpose-made straight connector allows two compatible sections to be joined while maintaining a direct airflow path through the joint.
For the most efficient installation, keep duct runs as short and straight as practical and support the duct correctly to prevent sagging or excessive compression.
Why use a galvanised steel duct connector?
Ventilation joints need to remain secure while air is continuously moved through the system. A rigid galvanised steel connector provides a stable surface onto which compatible ducting can be secured.
Galvanised steel is widely used for ventilation fittings because it combines structural rigidity with a protective zinc-coated surface.
The result is a straightforward fitting suitable for both permanent and semi-permanent ventilation installations.
Compatible 315mm ventilation equipment
The straight connector can be incorporated into a wider 315mm round ventilation system containing appropriately sized components such as:
- 315mm flexible ventilation ducting
- Compatible 315mm rigid round ducting
- 315mm inline extraction fans
- 315mm carbon filters
- 315mm acoustic silencers
- 315mm tee pieces
- 315mm bends and elbows
- 315mm reducers and enlargers
- Suitable duct clamps, clips and sealing materials
Ventilation components described as the same nominal diameter can use different male and female connection arrangements. Always check the actual connection dimensions and fitting style of adjoining components before installation.

315mm Galvanised Straight Connector FAQs
Is a straight connector the same as a duct coupler?
The terms straight connector, duct coupler and duct joiner are commonly used for fittings designed to connect sections of round ventilation ductwork. Always check the required male or female connection arrangement when matching specific components.
What size ducting is this connector designed for?
It is designed for nominal 315mm round ventilation systems.
What is the connector made from?
It is manufactured from galvanised steel, providing a rigid connection point within the ventilation system.
Can I use it to join two pieces of flexible ducting?
Yes. A straight connector is commonly used to provide a solid joining point between compatible sections of flexible ventilation duct.
How do I secure flexible ducting to the connector?
Compatible flexible ducting can be secured using appropriately sized duct clamps or clips. The joint can also be sealed with suitable HVAC foil tape where required.
Can it be used with rigid ducting?
Yes, provided the adjoining rigid duct components use a compatible connection arrangement and dimensions.
Can this connector be used for extraction?
Yes. It is suitable for compatible 315mm extraction ducting systems.
Can it be used for air intake?
Yes. The fitting can also be incorporated into compatible intake and supply-air ventilation systems.
Does this fitting reduce from 315mm to another size?
No. This is a straight 315mm connector intended to maintain the same nominal duct diameter through the joint.
Will a straight connector restrict airflow?
Any joint can introduce some resistance, but a correctly installed straight connector maintains a direct airflow path and avoids the larger directional changes associated with bends and junctions.
Should I seal the connection?
Where minimising air leakage is important, secure the duct correctly and seal the joint using suitable HVAC foil tape or another appropriate ventilation sealing method.
Can I use this with a 315mm carbon filter?
It can form part of a ventilation system containing a compatible 315mm carbon filter, although the exact connection arrangement of the filter and adjoining ductwork should be checked first.
Is 315mm ducting suitable for high-airflow ventilation?
315mm is a large ventilation duct diameter commonly used in higher-airflow systems. Actual airflow depends on the fan, duct layout, filters and overall resistance of the installation.
