Polywater® EFW™ Electro Fusion Wipe cleans the pipe surface of gas, electrical, telecom, water or sewer PE conduits prior to the electro or butt fusion process. Installer should have a handy source of EFW-1 disposable wipes available to avoid reuse/contamination issues. EFW™ wipes can clean more area prior to shaving (scraping) the pipe. The wipe can also be used to clean off pipe shavers or any contaminant that could interfere with a good fusion process.
