Full port and fit detail for this tool
The Festool Kapex KS 120 is a sliding compound miter saw. It is known for clean cuts and strong dust pickup right at the blade. Even so, the port only fits Festool hoses out of the box, so hooking up a standard shop vac takes the right adapter.
The saw has a round dust port at the rear. Our PETG adapter plugs into it and steps it to any standard shop vac or dust extractor hose. No tape. No clamps.

Festool Kapex KS120 Dust Port: What Fits It
The Kapex uses Festool's own Cleantec connection at the rear. A Festool hose plugs into it. Our adapter plugs into the same inlet.
This is a Festool-only fit out of the box. A 2-1/2 inch shop vac hose is far too big and a 1-1/4 inch hose does not seal right. That gap is why you cannot just push a shop vac hose onto the saw.
A GulpDust adapter is made to fit the saw port on one end and your bigger vac hose on the other end.
How to Connect a Shop Vac to the Festool Kapex KS120
Clear any dust out of the rear port first. A clean port gives the best grip.
Push the tool end of the PETG adapter into the port. It is a friction fit, so it holds with a firm press. Then press your shop vac or dust extractor hose onto the other end.
Turn the vac on before you cut. The Kapex already pulls dust well at the blade, and a steady vac at the port catches what the guard throws off.
Why Miter Saws Need Good Dust Collection
A miter saw sprays a fan of dust and chips out the back with every cut. The Kapex catches more than most saws, but the fine dust that gets past still lands on the bench and floats in the air.
Pulling the dust at the port keeps your bench and floor clear and keeps more fine dust out of the air you breathe. A clean work area also means fewer chips under your stock, so your cuts sit flat and true.
For the best result, fit the adapter to the port and run a steady vac. Any shop vac with the right adapter does the main job.
Festool KS120 Dust Collection FAQ
Will a GulpDust adapter fit the Festool Kapex KS120 dust port?+
Yes. It is a round port at the rear of the saw, and our adapter plugs right into it. The other end matches your shop vac hose.
Does the Festool Kapex KS120 work with a regular shop vac?+
Yes, with an adapter. The port is a Festool size, and most shop vac hoses are 1-7/8 inch or 2-1/2 inch, which is much bigger. The GulpDust PETG adapter fits the saw port on one end and your vac hose on the other.
Do I need to buy the Festool hose for the Kapex?+
No. The Festool hose is built for this port, but it costs a lot. Our adapter joins a standard shop vac hose you already own to the saw port.
Do I need clamps to attach the adapter?+
No. The adapter is a friction fit. You press it into the port and it holds. The vac hose end works the same way.
Do you sell the design file?+
No. We sell the finished part. Each one is printed to order in PETG and ships from the US.
