Spiral Ductwork (Pipe, Fittings & Components)
Spiral ducts come in 10' standard lengths and custom lengths up to 20'. Fittings are gasketed up to 20" and flange connections 22" - 30". Flange connections can be ordered in smaller sizes if requested. If you’re unsure what connection type or size range you need, send your drawings and we’ll confirm the right fit before fabrication.
Our spiral ductwork is popular with contractors because the products effectively prevent leaks due to the shape of corresponding joints. Spiral duct setups are known for being quiet, as low-pressure drops result in fewer vibrations moving about a system. Connect sections of your HVAC system using our spiral duct offerings in 45- and 90-degree configurations.
We also offer powder coating for spiral ducts in various colors to suit your client's preferences or building theme. Our inventory includes a comprehensive range of air duct fittings to make installations easy. Some of the spiral ductwork selections and components we have include:
