Ritmo TURBO pipe scrapers

Scraping HDPE pipe prior to electrofusion welding can be a tedious process, especially if you have a lot of welds to do. Small bore pipe (20-63mm) tends not to be covered by the rotary scrapers, which is why Ritmo designed and patented the TURBO scraper.

It fits on to the end of your cordless drill, and is capable of both scraping the pipe to be inserted into the fitting, and also squaring the end of the pipe to ensure even insertion into your coupler. Fast, simple, excellent results. Great Italian design.
