Cable and Pipe Entry Seals
For cable and pipe penetrations through walls, floors and equipment enclosures, AMPdossen provides modular sealing systems that form durable barriers against water, fire, dust and gas in critical infrastructure such as metro systems, utility tunnels, substations, data centers, healthcare facilities and chemical plants.
Selecting a cable or pipe entry requires the cable or pipe diameter, wall thickness, fire resistance rating and watertightness requirements. Contact us for an integrated solution.

One Flexible Modular Solution
Protecting Every Entry
AMPdossen cable and pipe sealing systems use a modular design comprising elastomeric sealing elements, metal or engineering-plastic frames and compression units. The system forms a secure seal around cables or pipes of different diameters, providing water and dust protection rated IP66 or higher and meeting fire resistance ratings from EI 60 to EI 120 where required.
The system can be set in concrete in new structures or retrofitted in existing buildings. Adjustable modules can be reconfigured as cable quantities change, simplifying maintenance and future capacity expansion.
- Water / Dust Protection
Rated IP66 or higher - Fire Resistance
EI 60 / EI 120 options - Air-Pressure Differential Resistance
For airtight or positive-pressure rooms - Modular Expansion
Easy cable additions and removals
Cable Entries
Designed to seal power and communications cables passing between spaces. The range includes ARD rectangular cable entry systems, ARK round cable press seals and ADG single-entry cable press seals, providing complete solutions for different wall constructions and cable types.
- Rectangular / Round
Multiple opening formats - Split Construction
Staged installation - Power / Communications
Wide cable diameter range - Water and Fire Protection
Multiple performance ratings
ARD Series · Rectangular Cable Entry System
A rectangular modular cable entry system with a steel frame for multiple cable circuits passing through walls and floors. Modular elastomer blocks and compression components enable efficient installation on site.
- High-density, multi-circuit cable penetrations
- Combined water, fire and dust protection
- Recommended for substations and metro main substations
ARK Series · Round Cable Press Seal
A compact, adaptable cable press seal installed in core-drilled holes or wall sleeves. Modules accommodate different cable diameters and can be added or replaced later to simplify maintenance and expansion.
- For core-drilled holes or wall sleeves
- Modules can be replaced in stages to support expansion
- Recommended for plant rooms and control buildings
ADG Series · Single-Entry Cable Press Seal
An easy-to-install solution for one or a small number of cables passing through a wall. It provides economical, effective point sealing for tanks, process equipment enclosures and building entries.
- Single- or dual-cable penetrations
- Equipment enclosure and building-entry sealing
- Compact construction and straightforward installation
Pipe Entries
Pipe entries through walls or floors are vulnerable points for water, gas and fire migration. AMPdossen AKD modular pipe seals provide matched annular space seals for different pipe materials, diameters and sleeve configurations.
- Water / Gas / Oil Lines
Multiple media applications - Annular Space Seals
For circular openings - Building Entries /
Utility Supply-Line Entries - Withstands Mechanical Stress
And pressure differential changes
AKD Series · Modular Pipe Seal
A reinforced modular pipe seal with high pressure resistance for locations exposed to sustained hydrostatic pressure, including projects with high groundwater levels, utility tunnels and tunnel exterior walls. It maintains a reliable seal under long-term water and soil pressure.
