A complete HVAC system consists of more than just straight ductwork. Elbows, tees, adapters, valves, and grilles play a crucial role in completing the air distribution network.
If the fittings are not compatible with the pipe body, the contractor may have to make adjustments on-site.
1. Accessories affect installation possibilities.
An accessory that's the wrong size can cause:
- Cannot be installed.
- It needs trimming.
- Increase the workforce.
- Behind schedule.
2. Common accessories
| Accessory | Function |
| Co | Change direction |
| Fuck off | Connect/Redirect |
| Numb | Branch |
| Transfer | Change the cross-section |
