S+K Technik cleaning brush attachment 72964H

This boiler cleaning brush attachment has a nominal diameter of 40 mm and an ergonomic design. It is intended for removing soot, scale, and debris from flue gas passages, heat exchanger tubes, and boiler chambers. The diameter matches internal pipe surfaces for effective contact.

Replacement brush attachments of this type are selected by the internal diameter of the flue way; the brush should match this diameter closely to avoid surface damage. The bristle material is chosen according to the deposit: wire bristles for hard scale, softer bristles for soot. Before ordering, verify that the attachment fits the handle or rod system, ensuring the connection thread or clamp is compatible. To install, undo the existing head and mount the replacement onto the cleaning rod.

Brush attachments wear out with use, reducing cleaning effectiveness. A brush that is too large can bend or jam inside the flue, while one too small leaves deposits behind. Such problems lead to reduced heat transfer efficiency and restricted flue gas flow. Check the bristle condition and confirm the brush size still matches the cleaned diameter.
