Measure to order
Dust port
Round port, friction
Look at the dust port on your WEN 20625. If it sticks out like a tube, measure the outside. On the 20625, if it is a hole, measure the inside. Use calipers.
Published size
WEN lists the dust port as 39.1 mm outer diameter, 34.8 mm inner diameter. (WEN manual, checked Oct 10, 2026)
Your port can differ. Measure yours and use that number.

Full port and fit detail for this tool
The WEN 20625 is a 20V cordless, 6-1/2 in. circular saw. It is a grab-and-go saw, and every quick cut leaves a spray of sawdust behind. Hooking a vac to the dust port catches that spray at the blade, so the mess stays in the vac instead of on your floor and in your air.
We print a GulpDust PETG adapter to your port measurement on one end and to your shop vac hose on the other, so the hose holds instead of falling off.

WEN 20625 Dust Port: What Connects To It
The 20625 has a dust port built into the guard. We print the PETG adapter to the size you measure there.
Most shop vac hoses are 1-7/8 in. or 2-1/2 in. Neither one seals on a saw port by itself. That gap is why dust sprays past the hose instead of going into it.
The adapter grips the saw port on one end and your vac hose on the other, so you get a snug fit.
How to Connect a Shop Vac to the WEN 20625
First, clear any packed dust out of the port, so it fits snug.
Press the tool end of the PETG adapter onto the port. We print it to the size you measure, so a firm push holds it. Press your shop vac hose onto the other end. Turn the vac on before the blade touches wood, so the first chips go into the hose.
A hose adds a little drag on a cordless saw. Drape it over your shoulder or clip it to your belt, so it feeds smoothly and does not pull the saw off your line.
Why Hook a Vac to a Cordless Circular Saw
Cordless saws get used everywhere: the garage, the deck, inside the house. That last one matters, because fine sawdust indoors hangs in the air and settles on everything.
The 20625 has a real port that a printed adapter can grab, so the vac you already own turns it into a clean-cutting saw. Cheap fix, big difference.
WEN 20625 Dust Collection FAQ
What fits the dust port on the WEN 20625?+
Our PETG adapter does. One end presses onto the saw port. The other end takes your shop vac hose.
Does the WEN 20625 work with a regular shop vac?+
Yes, with the right adapter. A shop vac hose and a tool port rarely match, so measure both. We print the GulpDust PETG adapter to your port measurement on one end and to your vac hose on the other.
Is the WEN 20625 adapter the same as the WEN CT1525 one?+
Not always. Ports can differ between saws, so measure the port on yours. The builder prints the adapter to the number you enter.
Do I need clamps or tape to attach the adapter?+
Usually not. We print the adapter to the size you measure, so you push it onto the port and it holds. The same goes for the vac hose end. Add a wrap of tape at any joint that sees heavy use.
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.
