POLISTAR, the line of flexible abrasive stars from PFERD INC. that has been developed for work on the hard-to-reach inner surfaces of bores and pipes, has just gotten even more effective with the introduction of POLISTAR-TUBE. POLISTAR-TUBE is a multi-stage tubing system that highlights the effectiveness of POLISTAR on even more hard to reach bore and pipe interiors. To prevent corrosion on stainless steel pipes, POLISTAR-TUBE is manufactured using stainless steel rivets exclusively.
