ULK double cone sealing stoppers

ULK double cone sealing stoppers or balloons with an inflation pressure of 1 bar are the ideal solution for any sewer plugging needs, repair work, rehabilitation, and leak testing. Each stopper is designed to cover a wide range of pipe diameters. The maximum sealing back pressure is 0.5 bar, equivalent to 5 meters of water column. The specific conical shape of these balloons allows for extremely versatile use in case of failures, renovations, and maintenance. Thanks to this geometry, the stopper can be used effectively for various profiles – egg-shaped, rectangular, or round. The high-quality material ensures excellent chemical resistance, low weight, and easy repair. Standard versions cover diameters from 250 mm to 2200 mm. Technical data: - Inflation pressure: 1 bar - Max back pressure: 0.5 bar (5 m water column) - Compatible profiles: Round, egg-shaped, rectangular - Material: High chemical resistance
