Full port and fit detail for this tool
The Makita DBO380 is an 18V LXT cordless finishing sander. It smooths flat surfaces and gets right into corners for a fine finish. Even light finish sanding makes very fine dust that hangs in the air.
The sander has a dust port on the side. We print our adapter to the size you measure there. Our PETG adapter plugs into that port and steps it up to any standard shop vac or dust extractor hose.

Makita DBO380 Dust Port: What Connects To It
The DBO380 has a dust port on the side of the tool. Our adapter is printed to plug into it.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch, which dwarfs it. That big gap is why a taped hose leaks fine dust everywhere.
A GulpDust adapter grips the sander port on one end and your vac hose on the other end. Firm push.
How to Connect a Shop Vac to the Makita DBO380
Clear any dust out of the side port first. A clean port gives the best grip.
Push the tool end of the PETG adapter into the port. We print it to the size you measure, 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 start sanding. A running vac makes a big difference in how much fine dust you catch.
Why Dust Collection Matters on a Finishing Sander
A finishing sander makes very fine dust. Fine dust is the kind that floats in the air and is the worst to breathe. It does not fall to the floor like chips do.
Pulling that dust at the port keeps more of it out of the air. It also keeps the surface clean so you can see your finish and get it smooth.
For the cleanest finish, run a steady vac while you sand. Any shop vac with the right adapter does the main job.
Makita DBO380 Dust Collection FAQ
What size is the dust port on the Makita DBO380?+
Measure it with calipers. It is on the side of the sander. Enter that number in the builder and we print the adapter to it. You pick the hose end you need.
Does the Makita DBO380 work with a regular shop vac?+
Yes, with an adapter. A shop vac hose and a tool port rarely match, so measure both. The GulpDust PETG adapter is sized to the sander port on one end and to your vac hose on the other.
Does a finishing sander need an adapter?+
A finishing sander makes less dust than a big sander, but the dust is fine and hangs in the air. You still need an adapter to join the sander port to a shop vac hose.
Do I need clamps to attach the adapter?+
Usually not. We print the adapter to the size you measure, so you press it into the port and it holds. The vac hose end works the same way. 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.
