Adapts Hose SizesThis Festool DC-D 36/27-AS reducing sleeve lets you connect a larger D36 or D32 hose to a Festool tool with a 27 mm dust port. That means you can keep using the hose you already own instead of piecing together a workaround on the job. 36 mm to 27 mmThe stepped reduction from 36 mm to 27 mm is the whole point here. It solves a common dust extraction mismatch and helps maintain a secure connection between hose and tool. Quick Insert FitIt attaches by inserting directly into the end of a D36 or D32 hose. No extra setup, no complicated hardware, just a straightforward hose adapter for dust collection setups that need to work right away.
Overview
The Festool DC-D 36/27-AS reducing sleeve is a vacuum accessory made to adapt larger Festool dust extraction hoses to tools with a smaller 27 mm dust port. This is a reducing sleeve designed for dust extraction hose adaptation. Model Number 768135. If you run Festool extractors and switch between tools with different port sizes, this small adapter solves that connection problem cleanly.
What it does is simple but important. The sleeve reduces from 36 mm to 27 mm and can also be used with a D32 hose, allowing you to connect either D36 or D32 hose setups to a Festool tool with a 27 mm dust port. That matters because a solid hose-to-tool connection is what keeps dust collection working the way it should. A loose or improvised fit means reduced suction at the tool, more cleanup, and more airborne dust where you do not want it.
Festool built this as a direct tool connection end, not a universal adapter that kind of works. It is made to insert into the end of a D36 or D32 hose, so setup stays fast and predictable. For anyone already invested in Festool CT dust extractors, that kind of plug-in fit is the difference between a clean system and a pile of mismatched accessories.
This part is best understood as a workflow accessory. It is not flashy, but it keeps a dust extraction system more usable across multiple tools. If one tool takes a 27 mm connection and your hose is larger, this adapter bridges that gap without forcing you to swap hoses every time you change tasks. On trim work, sanding, cleanup, and shop use, that saves time and keeps dust collection consistent.
The compatibility side is where this sleeve earns its keep. It is listed as suitable for all Festool CT systems and is intended for use with Festool D36 or D32 hoses. If your setup already revolves around Festool dust extractors and hoses, this is the correct kind of accessory to keep everything talking to each other without guesswork.
Who should buy it? Festool users who already own CT extractors and need to connect a larger hose to a smaller 27 mm tool port. It makes the most sense for woodworkers, remodelers, finish carpenters, and shop users who care about clean dust collection and want the right adapter instead of an improvised fit.
Simple Fix for Hose Mismatch
If your Festool hose is larger than the dust port on your tool, this adapter is the clean way to make the connection. It is a small part, but it keeps your dust extraction setup working the way it should.
