SpiroFlex Adapter F concentric 60/100-80/125 with spigots, white

The SpiroFlex Adapter F concentric 60/100-80/125 with spigots in white is a duct transition accessory designed to join concentric ventilation or exhaust systems of two different diameters. It provides a sealed mechanical connection between a 60/100 concentric duct and an 80/125 concentric duct, featuring spigots to ensure a secure fit and simplify installation in residential or light-commercial HVAC setups.

Advantages

The adapter offers a compact solution for diameter transitions while maintaining airflow continuity and minimizing leakage. Its white finish supports discreet integration into visible duct runs, and the included spigots allow for stable mechanical coupling without the need for complex fastening methods. The product is suitable for quick installation and reduces the need for custom-fabricated transitions.

Suitable for

• Connecting 60/100 concentric ducts to 80/125 concentric ducts in ventilation systems
• Residential kitchen or bathroom exhaust installations with concentric flues
• Light-commercial HVAC runs where space-efficient diameter transitions are needed

Key specifications

• Type: Concentric duct adapter with spigots
• Connection diameters: transition from 60/100 to 80/125 concentric systems
• Finish: White
• Application: Ventilation and exhaust duct transition
• Mounting: Spigot-mounted mechanical connection for airtight joins

How to use

Position the adapter between the two concentric duct sections so that each spigot enters the corresponding duct end. Ensure the mating surfaces are clean and aligned, then push the spigots fully into place to achieve a tight mechanical fit. Verify alignment and, where required by local codes or project specifications, secure the joint with approved clamps or sealing materials to maintain airtightness and prevent vibration or displacement during operation.

Usage recommendations

Inspect duct ends for damage or deformities before installation. Use appropriate sealing tape or HVAC-approved sealants if a higher level of airtightness is required. When installing in visible areas, handle the white finish carefully to avoid scuffs; if exposed to outdoor conditions, confirm compatibility with environmental factors such as UV exposure or temperature extremes.
