Savatech plugs of smaller diameters PLUGY Z and PLUGSY S can be used in all types of pipelines. Since these plugs are not reinforced with cord, they exhibit excellent stretching and sealing characteristics in pipe diameters from 20 mm up to 305 mm. Plugs are equipped with a car tyre inflation valve and can be inflated with a standard tyre pump. An eyebolt with a chain and a specially designed handle simplify manipulation of the plug.
