## Summary description

Pack of 10 SpiroFlex 75 gaskets/plugs designed for sealing duct collar connections and pipe sockets. Each piece matches 75 mm nominal diameter connections to prevent air leakage and provide a tight seal in ventilation, HVAC and ductwork installations. Suitable for repair, replacement or new installations where 75 mm collars are used.

## Long description

SpiroFlex 75 gasket/plug set (pack of 10) includes ten rubber gaskets/plugs designed to seal 75 mm nominal diameter duct collar connections and pipe sockets. The set is intended for ventilation and HVAC installations where a reliable mechanical seal is required to reduce air leakage at collar joints. Each gasket/plug conforms to the 75 mm collar profile and provides a compact, elastic seal suitable for repair, replacement or new installations in commercial and residential ductwork.
Advantages
The SpiroFlex 75 gaskets/plugs are made from elastic sealing material that adapts to minor irregularities in mating surfaces, ensuring a continuous contact seal around the collar circumference. Supplied as a pack of 10, the set allows multiple connections or staged replacements to be completed without individual purchases. The compact design preserves internal duct dimensions while creating a durable barrier against air leakage, reducing the risk of pressure loss and improving HVAC system efficiency when correctly installed.
Suitable for
 Sealing 75 mm duct collar connections in ventilation systems
 Repairing or replacing worn or damaged collar seals
 New installations of round ducts and pipe sockets with 75 mm nominal diameter
 HVAC maintenance tasks requiring quick gasket swaps
Key specifications
 Material: elastic sealing compound suitable for ventilation use
 Nominal diameter compatibility: 75 mm collar/socket
 Quantity: 10 pieces per pack
 Shape: ring/plug profile designed to match collar geometry
 Function: mechanical seal to reduce air leakage at connections
How to use
Clean the collar and mating socket surfaces to remove dust, debris and old sealant before installation. Fit the gasket/plug into the collar or socket by aligning the profile with the mating edge and pressing it evenly around the circumference until seated. For adhesive or mechanical fastening methods, follow any compatible product instructions; the gasket itself provides the primary sealing effect by compression. Verify the seal visually and, if possible, by conducting an air-tightness check or pressure test according to your system procedures.
Usage recommendations
Store the pack in a dry, shaded area away from direct sunlight and extreme temperatures to preserve material elasticity. Inspect gaskets for cuts or deformation before use. Replace gaskets showing wear or permanent deformation to maintain effective sealing and system performance.
