Built for Trenchless Pipeline Rehabilitation & Patch Repairs
The Sava Pipe Repair Plug and Packer range is engineered to repair and seal faulty pipework from small house connections up to municipal lines. Their multi-size design accommodates localized patch repairs ranging from 1 to 5 meters, helping restoration crews work faster while reducing equipment inventory.
Manufactured with a premium replaceable rubber sleeve and non-corrosive metal parts, these packers are built to withstand demanding pipeline conditions while remaining lightweight and highly flexible for seamless insertion through manholes, sharp bends, and tight cleanouts.
Packer Designs – What’s the Difference?
| Feature | Lateral Packers (HP-K) | Flexible Long & Bypass Packers |
| Primary Application | Optimized for trenchless repairs in smaller diameter pipelines, specifically inside residential and commercial house connection networks. | Engineered for standard main lines and extensive patch applications stretching between 1 and 5 meters in length. |
| Ideal Applications | House connection installations and lateral line repairsNavigating tight bends and multi-angle junctionsSmall-diameter localized pipe sealing | Long-distance localized main-line point repairsCuring repairs where continuous fluid bypass is mandatoryPrecision remote mapping in deep sewer pipelines |
| Design & Capabilities | Their bodies are intentionally rounded on both ends to simplify manual handling, tracking, and smooth insertion into tight, twisting lines. | Come standard with an integrated bypass channel to handle live water flows during the rehabilitation window, paired with a heavy-duty wheel system to facilitate flawless rolling deployment along the pipe. |
Key Features
-
Wide Repair Coverage Multi-size outer expansion profiles allow a single packer to conform to variable pipe internal diameters and patch lengths up to 5 meters.
-
Replaceable Rubber Sleeve Outfitted with an easily interchangeable outer rubber sleeve, heavily extending the lifespan of the core pneumatic structural asset.
-
Highly Flexible & Bend-Friendly Lightweight and incredibly pliable construction allows the packers to easily bend around corners and slip through standard manholes without binding.
-
Non-Corrosive Metal Parts Fabricated entirely with high-grade, corrosion-resistant metal fittings to survive constant contact with chemical grouts, resins, and aggressive wastewater.
-
Integrated Bypass & Wheel System Supports continuous flow-through capability to minimize line backup during curing, while the balanced wheel sets ensure easy, stable positioning down the pipeline.
-
Min.-Max. Contact Indicators Features clear visual indicators showing the minimum and maximum structural contact areas for foolproof positioning and safe field operation.
Available Sizes
The range provides targeted modular lengths and diameters built for residential laterals up to large civil stormwater and wastewater conduits. Standard configurations include:
