uPVC Pipe Fittings, uPVC Solvent Weld Fittings, uPVC Reducer Bushing, uPVC Bush, uPVC Bush Connector, uPVC Bush Reducer, uPVC Bushing Reducer, uPVC Reducing Bush

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.
The uPVC bushing fittings with solvent weld is regularly UV- stability, which is suitable for both indoor & outdoor use. Made by high quality of Unplasticised Polyvinyl Chloride material, uPVC bush reducer fittings are suitable for cold water supply, with max. Working temperature 60℃.
The uPVC reducing bushing is regularly provided in grey color, but the other colors are also available as per customers’ request.
SUNPLAST uPVC solvent reducing bush fittings can be provided in a size from 25*20mm to 400*315mm, with a normal working pressure of PN10 bars & PN16 bars, and are manufactured and tested in accordance with the domestic standard GB/T10002.2-2003, at the same time, they can also comply to international standards of ISO 4422-3:1996; ISO 1542-3:2009.
