Sava – High Performance Plugs – PLUGY HPF & PLUGSY HPF

When the job demands dependable pipe isolation, testing, or flow stopping under more demanding conditions, the Sava PLUGY HPF & PLUGSY HPF high-performance range at HTC delivers industrial-grade performance trusted by contractors, utilities, and civil infrastructure teams.

Designed for maximum strength, durability, and safety, these multi-size pneumatic pipe plugs are made from a high-quality rubber mixture with additional built-in aramid reinforcement, allowing them to ensure reliable functioning and withstand higher back pressures across all types of pipelines from 100 mm up to 2400 mm. They feature an extra-strong aramid reinforcement construction, a wider range of large bypass flows (including 4″, 6″, and 8″ openings) on the PLUGSY models, and heavy-duty eyebolts with quick coupling to simplify manipulation. Perfect for flow stopping and pipe tightness testing, this specialized range is also available in oil-resistant versions for demanding pipeline maintenance applications.

Built for High-Performance & Demanding Pipe Applications

The Sava PLUGY HPF and PLUGSY HPF range is engineered to seal and test pipework from 100mm through to 2400mm diameter. Their overlapping multi-size design means fewer plugs are required on-site, helping crews work faster while reducing equipment inventory.

Manufactured from a high-quality rubber mixture with additional built-in aramid reinforcement, these plugs are specially designed to withstand higher back pressures and perform reliably under the most demanding conditions. Despite their heavy-duty construction, they remain highly flexible for seamless deployment and insertion into the pipeline network.

Feature PLUGY HPF – Blocking Plugs PLUGSY HPF – Bypass Plugs
Primary Function Designed for complete pipe sealing and isolation under high-pressure conditions. Includes an integrated bypass, allowing high-capacity flow-through capability or fluid diversion while maintaining a secure pneumatic seal.
Ideal Applications High back-pressure flow stoppingPipe maintenance and repair in demanding environmentsReliable leak detection and line isolationPipe tightness testing Pipeline tightness testing with high-volume flow-throughLarge-scale temporary bypass operationsControlled drainage and diversion in municipal linesHigh-pressure flow management during utility works
Design & Capabilities Robust aramid-reinforced construction ensures maximum safety and stability when blocking high-volume flows. Bypass sizes are available in a wider range of large diameters, including 1″, 2″, 4″, 6″, and 8″ openings depending on the plug size, supporting high-volume flow management during critical operations.
