The MK4 Rotary Scraper is a professional tool designed to prepare PE pipe surfaces before the welding process. The scraper removes the oxidized polyethylene layer, ensuring an ideal surface for electrofusion welding.
The outer layer of PE pipe changes due to UV radiation and oxidation. The oxidized surface does not guarantee proper connection during electrofusion welding. Precise removal of the oxidized layer is crucial to ensure the durability and tightness of the connection.
The MK4 scraper was designed with professional pipe system installers in mind to ensure the highest quality surface preparation before welding.

Adjust the tool to the pipe diameter
Mount the scraper on the pipe
Rotate the scraper around the pipe, making complete rotations
Control the resulting chips - they should be continuous
If necessary, repeat the process for even surface scraping
Lock the scraper securely on the pipe
Rotate the scraper around the pipe with even pressure
Check if the entire surface is evenly scraped before removing
