Pittsburgh, are you familiar with the Perma-Liner End Seal? The Perma-Liner End Seal is a seamlessly molded seal that provides a large sealing surface. When the Perma-Liner End Seal is exposed to water, it swells to create a positive compression seal preventing any water to tracking between the liner and host pipe. The Perma-Liner End Seal forms a highly effective seal compatible with all types of mainliners due to their cylindrical shape. Pittsburgh, find this patented technology at our Perma-Liner US Tour stop in Louisville, Kentucky on Wednesday, August 13, 2014. Registration is FREE!
