Two-ended reducer with a 150mm female spigot and a 100mm male spigot made from PETG. Intended for joining solid or flexible plastic ducting in indoor and outdoor ventilation systems.
Fast, tool-free connections - with 150mm female and 100mm male spigots
One end includes a 150mm (6 inch) female spigot that fits over male fittings, while the other end is a 100mm (4 inch) male spigot that inserts into 100mm straight ducting or 102mm flexible ducting. The geometry is shaped for quick push-on installation.
Speedy assembly saves time on site, making loft and cupboard runs easier to join without specialised tools.
Weather and temperature tolerance - thanks to PETG construction with defined range
Made from high-quality PETG plastic with a specified operating range of -15°C to +60°C, designed to resist external factors and maintain shape. Suitable for use in both inner and outer parts of buildings.
Stable performance in typical household and light-external conditions, helping avoid warping or premature failure.
Versatile ventilation compatibility - with support for solid and flexible ducting
Designed to convert between 150mm and 100mm ducting and to join different plastic pipe types, whether solid or flexible. The male and female spigots match common duct sizes used in household ventilation.
