ECS1-Z with mastic, for valves

ECS1-Z are to be used to end-up of pre-insulated pipes in ball-valves for drainage and venting of the district-heating pipelines. ECS1-Z are effectively sealing and protecting against moisture penetration. ECS1-Z are resistant to UV, aggressive factors as well as fungus and mildews. They are with especially designed asymmetric shape allowing their application through the spindle of the valve.
