Festool D 27, D 27/32 and D 36 hoses: sleeves and connectors

Festool's D 27, D 27/32 and D 36 designations, the 577162 sleeve, the 452892 CT 22 and CT 33 connector and the 204920 D36 adapter, and what they do not cover.

Also listed as D27, D36, D 27/32, D36/32

Short answer

D 27, D 27/32 and D 36 are Festool's own hose and flange designations. Festool's 577162 sleeve joins D 27 and D 27/32 hoses to tools with D 27 and D 36 flanges by a bayonet fitting; its 452892 connector, 58 mm external diameter, joins D 27 hoses to the CT 22 and CT 33; and its 204920 joins D36 or D36/32 antistatic hose to Festool mobile extractors. The catch: Festool's wording covers its own parts, not other brands' 27 or 36 mm ports. See Festool hose sleeves.

Watch out for

  • The 452892 connector is for the CT 22 and CT 33 only, per Festool.
  • Festool says antistatic performance needs a complete antistatic system of extractor, hoses, sleeves and couplings. That is Festool's statement about its own system, not a safety promise.
  • A Festool D 36 flange is not the same thing as another brand's 36 mm hose; see 35 and 36 mm hoses.
