## Summary description

SpiroFlex 75 mm end caps made of polypropylene (PP), supplied as a set of 10 pieces with integrated gaskets. Designed to close 75 mm openings on duct boxes or ventilation fittings, these end caps provide a sealed termination to prevent air leakage and dust ingress.

## Long description

SpiroFlex 75 mm PP end caps are injection-moulded closures made of polypropylene, supplied as a set of 10 pieces with integrated gaskets. Each cap is designed to seal a 75 mm circular opening on duct boxes or ventilation fittings, providing a dust-tight and air-tight termination. The polypropylene construction offers chemical resistance and dimensional stability suitable for HVAC installation, maintenance, temporary sealing during transport or storage.
Advantages
The polypropylene material ensures lightweight durability and resistance to common HVAC contaminants. Integrated gaskets create a reliable seal without additional sealant, reducing installation time. Supplied as a set of ten, the caps are convenient for projects requiring multiple closures or for keeping spare parts on hand. The simple push-fit design enables fast application and removal while maintaining a consistent fit for 75 mm duct openings.
Suitable for
Sealing 75 mm openings on duct boxes and ventilation fittings
Temporary sealing during transportation and storage
HVAC installation and maintenance work
Preventing dust ingress and minimizing air leakage during assembly
Key specifications
Material: polypropylene (PP)
Diameter: 75 mm nominal for circular duct openings
Quantity: set of 10 caps
Seal: integrated gasket for air- and dust-tight closure
Fit type: push-fit / snap-in closure for duct box apertures
How to use
Align the cap with the 75 mm opening and press firmly until the gasket seats against the duct edge. Ensure the gasket compresses evenly around the perimeter to achieve an airtight seal. To remove, grip the cap and pull evenly while twisting slightly if necessary. For repeated use, inspect the gasket for wear or damage and replace caps when the seal no longer compresses properly.
Usage recommendations
Use these end caps for indoor HVAC systems and protected environments. Avoid prolonged exposure to direct sunlight or high temperatures above typical indoor HVAC ranges to prevent material deformation. Clean the sealing surface of dust and debris before installation to maintain sealing performance. Store caps flat in a dry area to preserve gasket elasticity.
