Festool dust-extractor hoses are commonly grouped into three size families: 27 mm, 36 mm and 50 mm. For most handheld Festool tools, a 27 mm hose is the compatibility-first choice. A 36 mm hose can move more air and is often useful for cleanup or tools that produce larger chips, provided the tool port accepts it. A 50 mm hose is intended for compatible high-volume cleaning, connection and extension arrangements rather than as a universal power-tool hose.
Those are useful starting points, not universal fit rules. Festool also sells tapered hoses labeled D 27/32, supplied equipment varies by extractor model and package, and the connection at the tool matters just as much as the nominal hose diameter. Check the exact tool, hose and extractor before ordering a replacement or adapter.
Festool Hose Sizes at a Glance
| Hose family | Typical use | What to check |
|---|---|---|
| 27 mm or tapered 27/32 mm | Sanders and broad handheld-tool compatibility | Whether the tool end fits inside or over the specific dust port |
| 36 mm | Cleanup and compatible high-chip tools such as some routers, planers and miter saws | Whether the tool accepts D36 directly or needs the correct reducer |
| 50 mm | Compatible high-volume cleaning, hose connections and extensions | It is not a direct universal tool connection; use the specified connector arrangement |
The D 27/32 label describes a tapered hose whose diameter changes along its length. It should not be read as a promise that every cuff or dust port measures exactly 27 or 32 mm. Festool’s current CT packages do not all include one identical hose, either. Before using the included-hose specification from another extractor as a buying guide, confirm the equipment list for your exact model and set.
When to Choose a 27 mm Hose
A 27 mm hose is the safest general recommendation for Festool tools with dust extraction, especially sanders and smaller dust ports. Festool’s own support guidance says its dust-extractable tools work with a 27 mm hose. The smaller, lighter hose is also easier to manage on a handheld tool where a heavier hose could tug at the tool or workpiece.
Connection direction varies by tool. On some tools, the reducing sleeve enters the dust port; on others, a hose cuff fits over the port. Do not rely on an inside-versus-outside rule that is presented as universal. The model-specific manual or accessory listing should control.
If you use a plug-it cord beside a 27 mm hose, cable management can help keep the pair from separating or catching on the edge of a workpiece. ToolCurve’s in-stock 27 mm coiled hose clips are one option for routing the cable along the hose. They are a convenience accessory, not a substitute for checking the hose and tool connection.
When a 36 mm Hose Makes More Sense
A 36 mm hose provides a larger airflow path. It can be useful for general cleanup and for compatible tools that create larger chips, including some routing, planing and miter-saw applications. Festool specifically identifies 36 mm options for many non-sander tools, but the tool must accept that connection.
A larger hose does not automatically fix every dust-collection problem. Collection also depends on the tool’s shroud, the shape of the port, extractor airflow and filter condition, hose length, restrictions at connectors, the material being cut and the extractor setting. An independent review of the CT 36 E AC likewise noted the effect of hose and connection losses and used the smaller 27 mm hose for sanding. Choose the hose around the complete system rather than diameter alone.
If a 36 mm hose needs to serve a tool with a 27 mm port, use an adapter designed for that exact transition. ToolCurve’s currently in-stock 36 mm hose to 27 mm tool adapter illustrates the sizing principle. Confirm the hose style and the tool model listed on the product page; matching two diameter numbers does not establish universal compatibility.
What the 50 mm Festool Hose Is For
The 50 mm family is a high-volume option for supported cleaning, connection and extension layouts. Festool’s current D 50 x 2.5 m anti-static hose is specified with a 50 mm diameter, 2.5 m length and two rotating connectors. That configuration is useful within the arrangements Festool documents, but it does not make D50 a direct fit for every power tool.
The KAPEX is a helpful example. Festool says its extraction outlet accepts a 27 mm hose internally or a 36 mm hose externally; it does not accept a 50 mm hose directly. When joining supported hose families, use the correct Festool connector sleeve and the appropriate rotating adapter arrangement. Do not assume that any two hose ends can simply be pushed together.
Smooth, Sleeved and Anti-Static Hoses
Hose diameter and hose construction answer different questions. Current Festool smooth-skin hoses are designed to slide past edges with less snagging. Sleeved versions can protect surfaces and, where provided, keep a power cord organized with the hose. Those features affect handling but do not change which dust port a cuff fits.
Festool anti-static hoses are designed to conduct static as part of a compatible Festool CT system. That can reduce nuisance shocks and static-related dust buildup in the intended setup. An anti-static label on the hose alone does not prove that a different vacuum, adapter or improvised connection provides a complete grounded path. Follow the extractor and tool instructions, particularly in applications involving hazardous or combustible dust.
Connecting a Festool Hose to Other Brands
Festool tools and hoses are designed as a system, but many workshops also use DeWalt, Makita, Milwaukee and other brands. Dust ports across those tools are not standardized. Festool notes that it does not make adapters for other manufacturers’ tool ports, so cross-brand setups require careful matching.
Start with two pieces of information: the exact Festool hose family and the exact tool model or measured port. Then choose an adapter whose listing names that hose and tool combination. The Festool hose adapters category is the main ToolCurve browse path. Model-specific listings are more reliable than selecting an adapter because its photo looks close to the port.
Test the assembled connection before beginning work. It should stay secure without forcing a brittle dust port, and it should not obstruct a guard or moving part. An adapter can solve a physical fit mismatch, but it cannot increase a tool shroud’s capture area or guarantee a particular collection rate.
Festool Hose Size FAQ
Can a 36 mm hose fit a 27 mm tool port?
Only when the tool is designed to accept that hose or when the correct reducer or adapter is used. Verify the tool model and both connection styles rather than relying on nominal diameter alone.
Can Festool hoses be joined?
Yes, in supported combinations. Festool documents a connector sleeve for the 27, 36 and 50 mm families along with the appropriate rotating-adapter arrangement. Use those instructions instead of improvising a joint that may leak or separate.
Which hose fits a KAPEX miter saw?
Festool’s support guidance specifies a 27 mm hose internally or a 36 mm hose externally at the KAPEX outlet. A 50 mm hose does not connect directly.
Does every Festool CT extractor include the same hose?
No. Included equipment varies by extractor model and package, and current listings may use tapered D 27/32 naming. Check the exact product page or manual for the set you are considering.
