摘要： A polymeric device for protection of the connecting pipe coupling contains a stepped bushing having a medium part with an increased diameter and two lateral parts with a smaller outside diameters, which is installed between end faces of pipes with a conic thread, and connected by means of a coupling and having sealing rings made of an elastomer, which are on parts of the bushing with the small diameter. The device has an additional stepped bushing, and the first stepped bushing has a constant outside diameter and two parts with small and large internal diameters, and the second stepped bushing has a constant internal diameter and two parts with small and large diameters.
