In the Festool system, hose sleeves and connectors are designed to provide optimal connectivity between the vacuum cleaner, extraction hose, and power tool. Bayonet or plug-in sleeves (e.g., Ø 27 mm or Ø 36 mm) are typically used on the tool side, while CLEANTEC sleeves with a rotating locking mechanism are often used on the extraction side. The system is antistatic, airtight, and can be flexibly combined. Many sleeves are equipped with a locking mechanism that prevents accidental loosening – for a permanently secure connection between the tool and the extraction unit.

The sleeves fit on third-party manufacturers in some places, but this is not always the case or makes sense.
