## Long description

The ALNOR CPSL-125 End Cap with Gasket is a professional-grade component engineered for the secure sealing of circular ventilation ducts. Designed specifically for 125 mm diameter ducting, this end cap features a factory-integrated EPDM rubber gasket that provides an airtight seal, effectively preventing air leakage and ensuring the overall efficiency of your HVAC system. Its robust construction makes it a reliable choice for completing ductwork runs in both residential and commercial ventilation projects.
Advantages
The primary benefit of the ALNOR CPSL-125 is its superior sealing capability, which is achieved through the high-quality EPDM rubber gasket. This integrated seal eliminates the need for additional sealants or tapes, simplifying the installation process while maintaining a high level of airtightness. The durable material ensures long-term performance and resistance to environmental factors, contributing to a stable and quiet ventilation system by preventing pressure losses and unwanted air noise.
Suitable for
Sealing the ends of circular ventilation ducts
Residential HVAC system installations
Commercial ventilation ductwork projects
Systems requiring airtight closure for 125 mm ducts
When it may not be suitable
This end cap is specifically designed for circular ducts with a 125 mm diameter and will not fit ducts of different sizes or shapes, such as rectangular or oval profiles. It is intended for standard ventilation applications and may not be suitable for high-temperature industrial exhaust systems or environments involving corrosive chemical vapors.
Key specifications
Diameter: 125 mm
Material: Galvanized steel
Seal type: Integrated EPDM rubber gasket
Compatibility: Circular ventilation ducts
How to use
To install the ALNOR CPSL-125, ensure the end of the ventilation duct is clean and free of debris. Simply slide the end cap into the duct opening. The integrated EPDM gasket will compress against the inner wall of the duct, creating a secure and airtight fit. No additional tools or sealing materials are typically required for a standard installation, though ensuring the cap is fully seated is essential for optimal performance.
What to consider before purchase
Verify the exact diameter of your ventilation ducting
Ensure the duct material is compatible with steel fittings
Check if the system requires a removable cap for future maintenance access
Usage recommendations: For the best results, ensure the duct edge is not deformed before insertion to maintain the integrity of the EPDM gasket. Regularly inspect the connection during routine HVAC maintenance to confirm the seal remains tight and free from obstruction.
