The long multi-size inflatable pipe plug DN 70–150 seals and shuts off pipes with a diameter of 68 to 165 mm. Its round body is made in one piece without a longitudinal seam, which makes it tight and hard-wearing. Natural rubber with a fabric insert keeps it dimensionally stable, weatherproof and temperature-resistant.
Strong profiled grooves give a secure hold in pipes and sewers. The plug is inflated through the compressed air coupling, for example with a foot pump or compressor. The sturdy eye on the front is used to secure the plug with a safety line, available separately as an accessory.
