Thomas C. Wilson - Expanding Tube Scraper

Expanding Tube ScraperCaldera Hollín Brush

The Wilson Expanding Scraper compliments the Wilson Expanding Brush, and it is recommended for removing soft, wet, or gummy deposits, such as mud or marine growth. The Wilson Expanding Scraper cleans tubes from 5/8-inch to 61/2-inch (15.9 to 165.1mm) OD. The blades in the Wilson Expanding Scraper do not fill with debris - as they do when cleaning soft and gummy deposits with a brush, and they are easily and quickly replaced as they wear. As the scraper head spins, the scraper blades lift up and scrape away deposits in the tube. The blades rise to conform to changes in the inside of the diameter of the tube, providing a very effective cleaning action throughout the length of the tube. The Wilson Expanding Scraper can be used with any Wilson electric, pneumatic, or air-driven tube cleaning system, and with a flexible holder it can be used to clean curved tubes, such as those found in water tube boilers.
