The long multi-size inflatable pipe plug DN 500–1000 is designed for large pipe diameters. It closes and seals reliably during inspections and maintenance or as temporary flood protection. Its round body is made in one piece without a longitudinal seam, from natural rubber with an internal fabric reinforcement.
Strong profiled grooves give a secure hold, even in uneven pipes. The plug is inflated through the compressed air coupling with a compressor or pump and can be reused when handled correctly. The sturdy eye on the front is used to secure the plug with a safety line, available separately as an accessory.
