The Swab pigs are manufactured using open cell polyurethane foam. These pigs are used for proving, sweeping and drying lines. The flexible nature of these pigs makes their bend radius greater than other poly foam pigs. One of the ends is coated with Inline’s MAXITHANE™, our custom blend of polyurethane.
