Central Vacuum Pipe is available in 5' lengths that can be purchased separately or in bulk. The inside of this pipe has a gel-coated inside finish to enable dirt to move freely. It is designed specifically for central vacuum systems.
The 2" OD size connects to all brands of central vacuum units made in the 1990's and later and fits central vacuum fittings and inlets. Kenmore, WalVac, Vacuflo and Black & Decker systems installed prior to 1990 may have used smaller diameter pipe. Adaptors are available when adding to or repairing these systems.
