Plastic bristle foam pigs are used for cleaning plastic pipes (PVC, fiberglass, HDPE) as well as internally coated steel pipe. The bristles are aggressive enough to clean most buildups, but not harmful to the pipe’s integrity. Models are available in light, medium, and heavy density foam. The pigs are constructed from an open-cell polyurethane foam with a durable polyurethane elastomer coating in a criss-cross pattern and embedded with plastic bristle straps.
