McMaster 3627K211 Electric Tube Cleaner Brush with Stainless Steel Bristles, 1/4" Diameter

Force out tough tube blockages with these powered cleaners. Pair the tube cleaner with a flexible shaft and then attach a brush or scraper to the shaft (each component sold separately). Water flows past the shaft to flush out loosened deposits. To power the cleaner, connect a three-prong (NEMA 5-15) extension cord. 

Brushes remove soft deposits and light scale. The bristles won’t leave behind debris that could cause rust on your workpiece. Match the brush diameter to your tube ID.

Scrapers remove light-to-medium deposits.

Flexible shaft with adapters connects to brushes with 8-32 and 12-24 female threads. Not for use with scrapers.
