Frequently Asked Questions

Q: What size ducts does this 100mm T/Y duct connector fit?

A: This connector is designed for standard 100mm (4-inch) round ventilation ducts and flexible hoses. It features a flange-style connection that pairs with both rigid PVC ducting and flexible aluminium or plastic hoses commonly used in home and commercial HVAC systems.

Q: What is the difference between the T-shape and Y-shape duct connector?

A: The T-shape connector branches at a 90° angle, making it ideal for tight spaces or right-angle duct layouts. The Y-shape connector branches at a more gradual angle, which can improve airflow efficiency and is well-suited to longer duct runs. Choose the shape that best suits your installation layout.

Q: How do I ensure an airtight seal with this duct connector?

A: Once the connector is inserted into your ducting, secure each joint using hose clamps or aluminium duct tape. The thickened ABS body creates a snug base fit, and using clamps or tape over the junction ensures minimal air leakage and maximum ventilation efficiency.

Q: Is this connector suitable for bathroom exhaust fans and kitchen range hoods?

A: Yes! This 3-way splitter is well-suited for bathroom exhaust systems, kitchen range hood ducts, grow tent ventilation, dryer exhausts, and general fresh-air distribution. It is rated for pressures below 850 kPa, covering the requirements of most residential and light commercial ventilation applications.
