Project-Specific Sealing for Cable & Pipe Penetrations
Hauff-Technik HRD b30 is a customised press seal manufactured to match customer-specific dimensional requirements for sealing new or already installed cables and pipes. Unlike fixed-size sealing solutions, each HRD can be configured around the actual penetration geometry, making it suitable where standard openings or conventional cable arrangements do not meet project requirements.
The seal is available in closed or split construction and can be produced for eccentric entries, overlapping flanges, multiple entries and mixed cable-and-pipe arrangements. This flexibility allows the individual press seal to maximise the available installation space while creating a purpose-built cable penetration seal around the services passing through the opening.
With a 30 mm sealing width, 5 mm press plates and compatibility with core drills or wall sleeves from 40 mm diameter upward, the HRD b30 provides a configurable cable press seal for demanding building and infrastructure penetrations. Cable or pipe outside diameters can start from 5 mm, while the configurator supports highly varied opening and service dimensions.
Dutco supplies individual press seals for customised cable entries with reliable watertight and gastight sealing. The HRD b30 provides a dependable cable entry sealing system for projects requiring tailored geometry, durable materials and controlled sealing around individual or multiple penetrations.
Customised Sealing for Project-Specific Entry Geometry
- Customer-Specific Manufacturing – Each seal is produced according to the dimensional requirements of the actual installation.
- Closed or Split Design – Allows use with new services as well as already installed cables or pipes.
- Eccentric Entry Configuration – The service opening can be positioned away from the centre where the penetration layout requires it.
- Multiple & Mixed Entries – Supports several cables, pipes or mixed services within one cable penetration sealing system.
- Maximum Space Utilisation – Custom positioning allows better use of the available penetration area.
- Project-Specific Solution – Provides a custom press seal where standard circular or centrally positioned arrangements are unsuitable.
Watertight, Gastight & Radon-Proof Protection
- Watertight Sealing – Helps prevent water passing through the annular space around cables and pipes.
- Gastight Performance – Creates a sealed interface to restrict unwanted gas transfer through the penetration.
- Radon-Proof Construction – Hauff-Technik identifies the HRD b30 as radon-proof.
- FHRK-Certified – Manufactured and tested according to the FHRK test specification.
- Waterproof Concrete Compatibility – Suitable for waterproof-concrete stress classes 1 and 2.
- Mechanical Sealing Principle – Provides a purpose-engineered alternative where a cable penetration sealing compound is not the selected sealing method.
Types
Because the HRD b30 is individually manufactured rather than supplied as a small set of fixed models, Hauff-Technik defines the product through configurable design types. These include closed, split, eccentric, flange-equipped, multiple-entry, mixed-entry and blind-seal arrangements.
Closed HRD b30
The closed version is intended for installations where cables or pipes can be passed through the prepared openings during installation.
- Suitable for new cable and pipe installations
- Manufactured according to specified opening and service dimensions
- Provides a purpose-made individual press seal
- Can incorporate one or several service openings
Split HRD b30
The split design allows the seal to be assembled around cables or pipes that have already been installed, making it particularly useful for retrofit projects.
- Suitable for existing cables and pipes
- Avoids the need to disconnect or pull services through a closed seal
- Provides an adaptable cable press seal for renovation and upgrade work
- Configurable according to the existing penetration dimensions
Eccentric HRD b30
The cable or pipe opening does not have to be positioned centrally. Hauff-Technik's configurator allows an eccentric offset to be specified according to the installation arrangement.
- Suitable for off-centre service routes
- Helps accommodate restricted installation geometry
- Supports better utilisation of available penetration space
- Provides a tailored custom press seal for non-standard layouts
HRD b30 with Overlapping Flange
An overlapping or covering flange can be incorporated where the penetration design requires additional coverage around the wall or sleeve opening.
- Manufactured according to customer-defined dimensions
- Provides additional flexibility around the opening geometry
- Useful for specialised wall and sleeve arrangements
- Integrates with the overall cable entry sealing system design
Multiple & Mixed Entry HRD b30
A single HRD can accommodate multiple services, including combinations of cables and pipes, instead of requiring a separate seal for every penetration.
- Up to 50 entries can be configured through Hauff-Technik's online configurator.
- Supports cables, pipes or mixed service combinations
- Maximises available space inside the penetration
- Provides a consolidated cable penetration sealing system for complex service entries
Blind HRD b30
The configurator also allows the HRD to be produced with zero service entries, creating a blind seal for an unused penetration.
- Closes unused core drills or wall sleeves
- Maintains gastight and watertight protection
- Can preserve an opening for possible future requirements
- Uses the same configurable sealing concept as the standard HRD range
Standout Features & Benefits
Fully Customised Manufacturing
- Manufactured according to the actual installation situation and customer specification.
- Suitable for unusual cable, pipe and opening arrangements.
