Heat Exchanger Cleaning Heads — 5/8″ to 6-1/2″ Outer Diameter
The Expanding Scraper compliments the Expanding Brush and is recommended for removing soft, wet, or gummy deposits, such as mud or marine growth. The Expanding Scraper cleans tubes from 5/8-inch to 6-1/2-inch Outer Diameter. The blades in the Expanding Scraper do not fill with debris as they do when cleaning soft and gummy deposits with a brush and are quickly replaced as they wear.
