Sava – Pillow Shaped Plugs – PLUGY PILOW & PLUGSY PILOW
When the job demands dependable pipe isolation, testing, or flow stopping in the largest pipeline diameters, the Sava PLUGY PILLOW & PLUGSY PILLOW pillow-shaped range at HTC delivers industrial-grade performance trusted by contractors, utilities, and civil infrastructure teams.
Designed for low weight, high flexibility, and ease of storage, these multi-size pneumatic pipe plugs are flexible and fully foldable, allowing them to exhibit excellent handling and sealing characteristics across all types of pipelines from 600 mm up to 2000 mm. They feature a unique space-saving profile that requires a very small insertion diameter, allowing them to easily fit through a standard 600 mm manhole, and an inflation valve with a safety GEKA coupling to simplify manipulation. Perfect for large-scale municipal works, this specialized range is also available in custom-made dimensions to fit any specific pipeline diameter for demanding pipeline maintenance applications.

Built for the Largest Diameter Pipeline Applications
The Sava PLUGY PILLOW and PLUGSY PILLOW range is engineered to seal and test large-scale pipework from 600mm through to 2000mm diameter. Their unique construction and overlapping multi-size design ensure low weight and high flexibility during use and storage, helping civil crews work faster while reducing equipment handling constraints.
Manufactured with high-quality materials, these pillow-shaped plugs are flexible and fully foldable, making them remarkably easy to transport and insert into massive trunk lines, stormwater systems, and civil infrastructure channels.
PLUGY PILLOW vs PLUGSY PILLOW – What’s the Difference?
| Feature | PLUGY PILLOW – Blocking Plugs | PLUGSY PILLOW – Bypass Plugs |
| Primary Function | Designed for complete pipe sealing and isolation in massive diameter lines. | Includes an integrated bypass system, allowing flow-through capability or controlled water diversion while maintaining a secure pneumatic seal in large conduits. |
| Ideal Applications | Large main line pipe maintenance and repairTrunk line leak detectionHigh-volume stormwater and sewer line isolationGeneral municipal utility infrastructure sealing | Large-scale pipeline tightness testing with flow-throughTemporary main bypass operations during trunk line rehabilitationControlled drainage and flood management applicationsCivil, industrial, and municipal infrastructure maintenance |
| Design & Capabilities | Their lightweight, fully foldable construction allows teams to deploy a massive pipeline block quickly and safely without needing heavy mechanical lifting machinery. | Bypass sizes feature an integrated 2-inch female bypass diameter to support safe monitoring and controlled fluid passage during large-scale operations. |
Key Features
-
Flexible & Fully Foldable Unique pillow-shaped construction allows the plug to be completely folded down for compact, space-saving storage, transit, and handling.
-
600mm Manhole Friendly Squeezes into highly restrictive openings and safely fits through a standard 600 mm manhole entry point before inflation.
-
Small Insertion Diameter Requires a minimized entry clearance profile relative to its massive expanded footprint, facilitating deployment in difficult-access chambers.
-
Low Overall Weight Advanced, high-quality material selection heavily reduces physical bulk, making the deployment process safer and less labor-intensive for field crews.
-
Safety GEKA Inflation Coupling Outfitted with robust, industrial-grade safety GEKA couplings to guarantee secure, leak-free connection during the inflation phase.
-
Custom-Made Dimensions Available Can be tailor-made to fit any specific or non-standard pipeline diameter outside the baseline catalog sizes.
Available Sizes
The range provides extensive overlapping pipeline coverage spanning the largest infrastructure networks from 600 mm up to 2000 mm, with options for custom sizes. Standard coverage ranges include:
