Standard U-type sewer sealing stoppers

Standard U-type stoppers are ideal for fast and reliable plugging of pipes and circular channels. Made of high-quality natural rubber with fabric inserts, they ensure long-term resistance to heat, cold, water, and various chemicals. Thanks to their high expansion capacity, they cover a wide range of diameters. With an inflation pressure of 2.5 bar, they can withstand a water column of up to 10m (for diameters up to DN 1000). All models are equipped with a standard brass connection and a stainless steel eyelet for easy handling. The products are tested and certified by TÜV Süd, ensuring maximum safety during operation.
