Built for Large Diameter Pipe Applications
The Sava PLUGY and PLUGSY range is engineered to seal and test pipework from 40mm through to 1800mm diameter. Their overlapping multi-size design means fewer plugs are required on-site, helping crews work faster while reducing equipment inventory.
Manufactured with reinforced aramid cord construction, these plugs are designed to withstand demanding conditions while remaining highly flexible for insertion through manholes, bends, and tight access points.
