The I.S.T. Duo lip pig with replaceable lips is a special type of Duo lip pig that was designed especially for handling aggressive media. The advantage of this pig is that the seal lips can be replaced separately. The body of this pig is manufactured from a chemical resistant thermoplast such as PA 6 or PVDF. The replaceable sealing lips are typically manufactured from nonabrasive polyurethane or FKM (Viton). In most cases the Duo lip pig with exchangeable lips is applied with integrated magnet.
Our Duo lip pig with replaceable lips is only available in conjunction with I.S.T. pigging valves or systems!
