Mechanical Pipe Plugs
Tottight Aluminium Test Plugs (0,1 - 0,5 bar)
General specifications
Lightweight aluminium body with the Tottight tightening system for large-diameter pipe-end sealing, temporary blockage and low-pressure testing.
- Size range325 — 2000 mm
- Back pressure0,1 – 0,5 bar
- MaterialAluminium (NR/SBR, CR, EPDM seal)
- Bypass2" connection
- Working temp.−20 to +80 °C
Description & features
Tottight Aluminium Test Plugs are designed for large-diameter pipe-end sealing, temporary blockage, and low-pressure testing. Produced with a lightweight aluminium body and rubber sealing element, the plug uses a Tottight tightening system to compress the seal between the aluminium plates. This compression expands the rubber seal against the internal pipe wall, providing stable and secure mechanical sealing. The bypass connection allows controlled filling, drainage, pressure release, or flow management during operation.
Key Features
- Lightweight aluminium body: easier handling, positioning and installation on site.
- Tottight tightening system: compresses the seal between aluminium plates for stable, secure sealing.
- Large-diameter coverage: DN325 — DN2000, back pressure 0,1 – 0,5 bar.
- 2" bypass connection: controlled filling, drainage, pressure release or flow management.
- Seal material choice: NR/SBR, CR or EPDM, operating from −20 to +80 °C.
Application Areas
- Sanitary systems: air and water testing, temporary sealing, or controlled isolation.
- Sewerage pipelines: maintenance, blockage, testing, or flow management.
- Drainage lines: secure pipe-end sealing during inspection or repair works.
- Industrial pipelines: reliable sealing, low-pressure testing, or temporary blockage.
- Municipal infrastructure: pipe isolation and bypass flow control during repairs or installations.
- Wastewater systems: lightweight handling, stable sealing and controlled drainage during maintenance.
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.
