uPVC bush or uPVC bushing fittings, also known as uPVC bush reducers, are a lot like adapters, but with a focus on connecting pipes of different diameters by reducing the fitting. (Bushings cannot reduce pipe.) uPVC Bushing Reducer fittings are also typically threaded, which sets them apart from other types of fittings. This allows for different kinds of connections and makes maintenance and pipeline customization easier. Bushings are often seen in landscaping and aquaculture applications because they work better with water than metal fittings that may rust.
