Our British-made flexible sweeping kits and brushes are the ideal solution for cleaning lined and twin-walled chimney systems. The rods are fitted with solid brass ½″ Whitworth threaded couplings (female and male), providing a strong, smooth connection with no sharp edges – essential for preventing damage to flexible liners. Each sweeping brush is equipped with a protective ball top, which not only helps guide the brush through bends in the flue but also significantly reduces the risk of damaging or puncturing the liner. Compatible with our soft, medium, or hard sweeping brushes, these kits offer maximum safety, flexibility, and durability for the professional chimney sweeper.
