Twisted in wire brushes are known by many names, such as spiral, tube, bottle, pipe and more, but generally they are manufactured using the same construction technique.
A piece of wire is doubled over and bristle material is inserted between the fold of the wire stem, the wire stem is then twisted into a brush.
The most common brush “fills” are steel wire, stainless steel wire, brass wire, and nylon.
All Bordo condensor tube and boiler tube brushes feature a BSW male threaded ferrule.
They may be used by hand or with power equipment.
All brushes are available as single or double spiral.
The double spiral are a heavier construction with a more dense brush face for more aggressive brushing and are ideally suited to use with a power tool.
