Cap ends are fittings used in ductwork systems to close off the open ends of ducts. They are typically made from the same materials as the ducts, such as galvanized steel, aluminum, or plastic. Here’s how they are used:

Description

Simple flat pieces that seal the end of a duct. These are a “male” fitting which slide inside spiral ducts. Female cap ends can be fabricated to go directly onto a fitting

Uses in Ductwork Systems:

• Sealing Unused Ducts: Cap ends close off ducts that are not in use, preventing air loss and maintaining system efficiency.

• Maintenance and Testing: Temporarily sealing ducts during maintenance or testing procedures to ensure proper airflow and pressure within the system

• Terminating Duct Runs: Providing a clean, finished end to duct runs where no further extension is required.

In summary, cap ends are essential for sealing and protecting the ends of ducts, ensuring system efficiency, and preventing contamination in HVAC systems.
