AOQUN is a large-scale high-quality customized Tube Pipe Cleaning Brushes manufacturing company integrating R&D, production, sales and service. Twisted brushes, also known as tube or flue brushes, are an essential tool used in a variety of manufacturing applications. Our twisted brushes are manufactured by twisting a filament between stem wires. The brushes are then machined to the desired measurements and customer specifications. We offer a full range of filament material for our twisted brushes including wire, natural, synthetic, nylon and even aluminum oxide (which is popular in our market-leading automotive deburring brushes).
