The Spark-Lin™ weld spatter resistant tubing is specially designed for applications with incidental contact between weld spatter and tubing. We've combined a blue 95A durometer polyurethane core with a specially formulated flame-retardant jacket to create a tubing that sheds weld spatter before it can do any damage. The cover also meets UL 94 VO requirements, offers strong insulating properties, and resists a wide variety of oils, greases, acids, bases, and aqueous solutions.
