Red Series Polly Pigs

The Red Series pig bodies are made with Knapp's rugged and dependable K-Lite urethane foam. K-lite is a medium-density (7 to 8 lb/ft3) foam; the Red Series pigs are available with assorted coatings and scraper elements to perform the utility function required of the pig.

Blue Series Polly Pigs

Knapp's Blue Series pigs use the same basic K-Lite foam system as the well-known Red Series. With Knapp's unique ability to blend our own foam sytems, we alter the formulation of the urethane foam to make it softer, lighter (5 to 6 lb/ft3) and more flexible. The coating used for the Blue Series is also softer and more flexible than that found on the Red Series. The same coating patterns and scraper elements are available for the Blue Series.

Crimson Series Polly Pigs

The Crimson Series pigs use Knapp's K-Duro, our toughest and longest-wearing foam. K-Duro is a heavy-density (9 to 10 lb/ft3) foam ideal for pigs that have to travel long distances or perform hard scraping duty. The Crimson Series is available with the same coating patterns and scraper elements as the Red Series.

Maximum Cleaning Series Polly Pigs

The Maximum Cleaning Series pigs use both Knapp's K-Lite and K-Duro urethane foam bodies. Depending upon the particular application, straps of urethane scraper blades, steel wire brushs, silicone carbide chips, or hardened steel studs are applied to the pig bodies to produce the ultimate in scraping and flexibility.

Swab Series Polly Pigs

The Swab Series pigs use Knapp's lightest-density (1 to 2 lb/ft3) foam body with the same coating patterns and scraper elements aavialble for our other Polly Pigs.
