EASY TO INSTALL: Adaptor to convert between 150mm and 100mm ducting - 6 to 4 inch.This is a very practical robust solid duct reducer to be used when connecting two different plastic pipes, solid or flexible ducting together. Lightweight, quick, and easy to install. HIGH QUALITY MATERIAL: High-quality white Polystyrene/Polypropylene plastic Material. Max / Min Temperature: +60c / -15c. Designed and intended for use in the ventilation systems in both the inner and outer of the building, made of high-quality material, which is resistant to external factors (high quality PVC plastic). On one side there is a 150mm (6 inch) female spigot. Will fit over male fittings (bends etc). Requires additional 150mm male connector to connect round 150mm pipe.

This ducting reducer is designed to be used when decreasing or increasing the size of your inline ducting. The large end of the reducer (female) is designed to fit over extractor fan spigots and duct fittings with the smaller end of the reducer (male) designed to fit inside solid plastic and flexible ducting. If fitting the small end of the reducer to fan spigots or duct fittings, you will need a small piece of duct to enable a clean fit. If you require reducing directly from solid or flexible ducting, then a male coupler is required.
