The Hand-Launch Pig is a single-piece, bi-directional foam pig manufactured with long-wearing yet flexible urethane foam discs. They are designed to navigate dual-diameter situations well and especially good at running in PE pipe where weld joints require flexibility. Hand-Launch Pigs are available in both medium and heavy density urethane foam. Hand Launch Pigs can be modified to accommodate transmitters, magnets and/or radioactive sources. Hand Launch pigs come in medium (5lb), or high (9lb) foam densities.
