PRODUCT RANGE
The CaseCore End Seals range includes two specialised sealing systems designed to suit wall penetrations and casing pipe applications.
CaseCore Compenseal
Ø 16-90 mm
The CaseCore Compenseal is a flexible EPDM sealing collar designed for pipe penetrations where movement is expected. It accommodates axial and radial movement caused by thermal expansion, settlement and structural movement while maintaining a reliable watertight seal.
Ideal for pre-insulated pipelines and building penetrations, the Wall Flange Seal provides long-term waterproof protection for walls, floors and ceilings.
Key Applications
- Pre-insulated pipe systems
- Building wall penetrations
- Floor and ceiling penetrations
- Concrete structures
- Water and wastewater infrastructure
- Industrial pipelines

CaseCore End Seal Closed and Open
Ø 16-90 mm
The CaseCore End Seal is an elastomeric casing end seal designed to close the annular space between the carrier pipe and casing pipe, preventing the ingress of water, soil and debris while helping protect the carrier pipe against corrosion.
Available in two configurations to suit both new installations and retrofit projects.
Available Variants
- CaseCore End Seal Closed – A one-piece conical end seal designed for new pipeline installations where the seal can be installed before the carrier pipe is fully assembled.
- CaseCore End Seal Open – A split conical end seal designed for retrofit applications, allowing installation around existing pipelines without disconnecting the carrier pipe.
