3-Way Y Splitter Ducting & Pipe Reducer Connector | Made to Measure (20mm to 150mm)
UK-made 3-way Y splitter reducer connectors for ducting, dust extraction, waste pipe, HVAC, and ventilation systems – made to measure.
Whether you need to split airflow for workshop dust extraction, balance a domestic ventilation setup, or divert a pond filtration line, our custom-engineered Y piece connectors are manufactured to your exact requirements.
Simply select your main opening diameter from 20mm up to 150mm. The two branching ports are proportionally reduced to optimize flow and pressure (Branch Diameter = Main Diameter ÷ 1.5). Made from high-quality, heavy-duty plastic.
Key Features:
-
Bespoke Sizes: Available from 10mm to 150mm outer diameter to ensure a perfect, flush fit with your existing hoses or rigid pipes.
-
Proportional Flow Reduction: Designed with a 1.5x reduction ratio on branching arms to maintain stable pressure and balanced airflow/fluid dynamics.
-
Heavy-Duty Construction: Unlike standard, fragile plastic or cheap injected-mastic parts, our adapters are manufactured from Glass-Fiber Reinforced Glycol-Modified Polyethylene Terephthalate
-
Universal Applications: Ideal for woodshop dust extraction networks, inline extractor fans, grow tent ventilation, hydroponics, HVAC systems, and low-pressure plumbing.
-
Fast UK Manufacturing: Custom made to order in our UK workshop and dispatched directly to your door.
Sizing Guide Example:
-
Selecting 150mm main opening gives you two 100mm branch outlets.
-
Selecting 60mm main opening gives you two 40mm branch outlets.
-
Selecting 30mm main opening gives you two 20mm branch outlets.
How to Order the Right Size
To make ordering as easy as possible, both ends of our adapters are designed to slide inside your ducting and pipes
-
How to measure: Measure the inside diameter (ID) of your flexible ducting or pipe.
-
What to select: Choose that exact ID size from our dropdown menu. If your pipe/ducting measures 100mm on the inside diameter, select 100mm. We automatically apply a tiny tolerance behind the scenes so it fits inside snugly.
-
For Flexible Hoses & Ducting: Flexible ducting is designed to stretch over the exterior of this adapter and can be clamped down tightly with a standard jubilee clip if needed.
Technical Specifications & Safety Disclosures
Please review the following guidelines to ensure suitability for your specific workshop environment:
- Pressure Limits: Designed strictly for low-pressure/high-volume airflow and vacuum applications. Do not use in high-pressure compressed air lines or pneumatic system manifolds.
- Temperature Resistance: This specialised polymer safely handles continuous operational temperatures up to approx. 75°C. It is ideal for warm air extraction and portable AC exhausts, but must not be used for high-heat applications like gas boiler flues or direct heat-element venting.
- Chemical Resistance: Excellent native resistance to workshop oils, lubricants, and airborne particulates. Avoid prolonged exposure to harsh structural solvents like acetone.
Delivery time is typically 2-3 days from order and then shipment. We will supply sooner where possible.
