Inline Services manufactures many styles and sizes of urethane pigs. They are made from Maxithane™, a custom blend of high performance polyurethane, to ensure durability. Inline’s four standard Uni Series pigs include the Uni-Cup™, Uni-Plus™, Uni-Flex™, and Uni-Flex 2C. All urethane pigs come as a solid one piece construction, and have a combination of cups and discs spaced along the body. They are also available with our wrap brushes for heavier cleaning. Urethane pigs are capable of traversing 90 and 180 degree tees and sealing full port valves. This type of pig is great for batching, purging, and general cleaning.
