WEN 20625 Circular Saw Dust Port Size and Vacuum Adapter Guide
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.
WEN puts the port size right in the manual, which most brands do not bother to do. The port is 34.8 mm inside and 39.1 mm outside, or 1-3/8 in. and 1-1/2 in. A GulpDust PETG adapter matches that port on one end and your shop vac hose on the other, so the hose seals instead of falling off.

WEN 20625 Dust Port Size: 34.8 mm Inside, 39.1 mm Outside
The WEN manual lists the dust port size for the 20625: 1-3/8 in. (34.8 mm) inside and 1-1/2 in. (39.1 mm) outside. No calipers needed and no guessing.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. Neither one seals on a 34.8 mm port by itself. That gap is why dust sprays past the hose instead of going into it.
A GulpDust adapter is printed to match the saw port on one end and your vac hose on the other, so you get a snug fit with no tape and no clamps.
How to Connect a Shop Vac to the WEN 20625
First, clear any packed dust out of the port, so the seal is tight.
Press the small end of the PETG adapter onto the port. It is a friction fit, 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 with a published size, so a small printed adapter and the vac you already own turn it into a clean-cutting saw. Cheap fix, big difference.
WEN 20625 Dust Collection FAQ
What size is the dust port on the WEN 20625?+
The port is round. It is 34.8 mm (1-3/8 in.) on the inside and 39.1 mm (1-1/2 in.) on the outside. Those numbers come from the WEN owner's manual.
Does the WEN 20625 work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose is wider than the saw port. The GulpDust PETG adapter fits the port on one end and your vac hose on the other, so the hose stays put while you cut.
Is the WEN 20625 port the same size as the WEN CT1525?+
No. They are close but not the same. The 20625 port is 34.8 mm inside and the CT1525 port is 35.56 mm inside. Each saw gets its own adapter, so order by your exact model number.
Do I need clamps or tape to attach the adapter?+
No. The adapter is a friction fit. You push it onto the port and it holds. The same goes for the vac hose end.
Can I print this adapter myself?+
Yes. You can buy the printed PETG part shipped from the US, or download the STL file and print it at home. We suggest PETG with 3 walls and 25 percent infill.
