The Festool D 36 (1-7/16") x 7 m (23') Dust Extractor Hose is smooth, elastic and extremely robust, and will impress you with improved handling and a longer service life. The smooth, braided outer skin glides easily over any edges, and improved suction and flexibility are ensured due to its smooth, elastic interior. In addition to the conical geometry, the inside of the hose is smooth, further improving suction, and very elastic to improve flexibility. The re-designed CLEANTEC dust-extraction sleeve ensures a secure fit on the tool and offers clever extra benefits: the ends of the hose can be connected to each other, to transport cleanly without dumping residual dust everywhere, or extend the suction hose by connecting two or more together to make whatever length you need. Adapter and connector rotate for added convenience. The hose is temperature-resistant to 158°F (70°C). Not for use with Extractors with Auto-Clean.
