The key to efficiency is maximum tip contact to the surface – the tips of the brush are what provide proper cleaning. Select a brush with an outside diameter exactly the inside diameter of the pipe. A larger diameter brush will bend when entering the pipe providing less effective cleaning as the bristle tips will not contact the surface.
This will cause extra wear and tear on your brush, and may result in the brush getting stuck in the pipe. A smaller diameter brush with require additional passes in order to clean and may result in missed areas.
The handle of your brush should reach the entire length of your pipe or tubing for quick and effective cleaning. If you need help in finding the correct brush for your application, please do not hesitate to contact us at 800-826-8302 or see our collection of brushes online here.
