Sava – High Pressure Plugs – PLUGY HP 6 & 12 BAR
When the job demands dependable pipe isolation, testing, or flow stopping under extremely high back pressures, the Sava PLUGY HP high-pressure range at HTC delivers industrial-grade performance trusted by contractors, water utilities, and industrial maintenance teams.
Designed for extreme durability, safety, and heavy-duty performance, these multi-size pneumatic blocking plugs are engineered with special reinforcement, allowing them to exhibit superior sealing and structural containment characteristics across all types of pipelines from 100 mm up to 600 mm. They feature a robust construction capable of withstanding high back pressures up to 10 bar, a standard R 1/4″ inflation valve compatible with precise high-pressure controllers, and balanced, heavy-duty eyebolts to simplify manipulation. Perfect for critical main-line interventions, this specialized range is available in both 6 bar (87 psi) and 12 bar (174 psi) working pressure models for demanding pipeline maintenance applications.

Built for High-Pressure & Extreme Back-Pressure Applications
The Sava PLUGY HP range is engineered to seal and isolate high-pressure pipework from 100mm through to 600mm diameter. Their overlapping multi-size design means fewer plugs are required on-site, helping crews work faster while reducing equipment inventory.
Manufactured with a specialized high-strength reinforcement construction, these heavy-duty blocking plugs are designed to withstand exceptionally demanding field conditions and extreme back-pressure environments where standard pneumatic plugs cannot be deployed.
PLUGY HP 6 BAR vs PLUGY HP 12 BAR – What’s the Difference?
| Feature | PLUGY HP 6 BAR – High-Pressure Blocking Plugs | PLUGY HP 12 BAR – Extreme-Pressure Blocking Plugs |
| Primary Function | Designed for robust pipe sealing and isolation under standard high-pressure thresholds. | Engineered to withstand extreme back pressures up to 10 bar (145 psi) or more depending on pipe conditions. |
| Ideal Applications | Municipal water main maintenance and repairMid-tier high-head leak detection and testingMainline isolation under moderate active pressure headsGeneral utility sewer and high-volume stormwater works | Deep utility infrastructure and high-pressure flow stoppingIndustrial plant process lines and high-head refinery shutdownsHigh-pressure hydrostatic tightness testingCritical main-line water infrastructure interventions under intense pressure |
| Design & Capabilities | Specialized reinforcement allows field teams to quickly establish a reliable pipe block against active pipeline flows. | Upgraded, maximum-duty special reinforcement layout and ultra-robust build ensure maximum operator safety and uncompromised structural stability when holding back extreme fluid heads. |
Key Features
-
Wide Pipe Coverage Multi-size capabilities ensure a single plug spans multiple nominal pipe classes, cutting down on equipment overhead.
