Mechanical Pipe Plugs
Tensioner Tottight Aluminium Test Plugs (0,2 - 1 bar)
General specifications
Dual-action tensioning — vertical bolts compress the seal, horizontal bolts grip the pipe wall — in a lightweight aluminium body.
- Size range325 — 2000 mm
- Back pressure0,2 – 1 bar
- MaterialAluminium (NR/SBR, CR, EPDM seal)
- Bypass2" connection
- Working temp.−20 to +80 °C
Description & features
Tensioner Tottight Aluminium Test Plugs are designed for lightweight large-diameter pipe-end sealing, blockage, and low-pressure testing. The plug uses a dual-action tensioning system: vertical bolts compress the rubber seal between aluminium plates, expanding it against the pipe wall, while horizontal bolts press directly against the pipe wall for better grip, centering, and stability. The aluminium body reduces weight, making handling, positioning, installation, and removal easier on site.
Key Features
- Dual-action tensioning: vertical bolts expand the seal, horizontal bolts grip the pipe wall for centering and stability.
- Lightweight aluminium body: easier handling, faster positioning, reduced manpower.
- Large-diameter coverage: DN325 — DN2000, back pressure 0,2 – 1 bar.
- 2" bypass connection: controlled flow, drainage and pressure release.
- Seal material choice: NR/SBR, CR or EPDM, operating from −20 to +80 °C.
Choose the aluminium version when the application requires
- Lighter product weight
- Easier handling and installation
- Faster positioning on site
- Reduced manpower requirement
- Frequent installation and removal
- Low-pressure testing or temporary blockage
Recommended installation procedure
Plugline mechanical test plugs seal by compressing a rubber element against the pipe wall. Follow the procedure below for safe installation and removal.
01
Inspect
Check the plug body, rubber seal and bolts for damage. Confirm the reference matches the inner diameter of the pipe to be sealed.
02
Position
Clean the pipe end and insert the plug so the sealing element sits fully inside the bore, square to the pipe axis.
03
Tighten
Tighten the bolts evenly in a crosswise pattern. The rubber seal compresses and expands against the pipe wall until firmly seated.
04
Test
Apply test pressure per EN 1610 or local code, staying within the back-pressure rating. Use the bypass for filling, venting or drainage.
05
Release
Relieve pressure through the bypass, loosen the bolts and withdraw the plug. Clean and inspect before storage — reusable across many cycles.
