Bosch ROS20VSK Random Orbit Sander Dust Port Size and Vacuum Adapter Guide
The Bosch ROS20VSK is the Bosch 5 in. Variable Speed Random Orbit Sander. The dust port is round and about 28 mm at the outside. That number comes from an adapter made for this sander, so treat it as close, not exact. The inside size is not confirmed, so measure your own port before you buy.
A sander makes fine dust that hangs in the air and gets into your lungs. Pulling it right at the port keeps the air clean. A GulpDust PETG adapter is sized to the port on one end and your shop vac hose on the other end. It is a friction fit. No tape. No clamps.

Bosch ROS20VSK Dust Port Size: About 28 mm Outside, Round
The dust port on the ROS20VSK is round. The outside is about 28 mm. That figure comes from an adapter made for this Bosch sander, so treat it as close, not a hard spec. The inside size is not confirmed yet, so measure your own port before you buy.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. They are far too wide for a small 28 mm port. That gap is why fine dust sprays out instead of going into the hose.
A GulpDust adapter is printed to match the sander port on one end and your vac hose on the other end. Measure your port first so you order the size that seals tight.
How to Measure Your Bosch ROS20VSK Dust Port
Close caliper jaws around the OUTSIDE of the port stub. That gives you the outer diameter in millimeters. Round to the nearest standard size if your number falls between two.
Next, slide the inside jaws into the port and open them out until they touch the inner wall. That gives you the inner diameter. The inner is what the adapter slides into. The outer tells you how snug the fit will be.
How to Connect a Shop Vac to the Bosch ROS20VSK
First, clear any dust out of the port. A clean port gives the best seal.
Press the small end of the PETG adapter onto the port. It is a friction fit, so it holds with a firm push. Then press your shop vac hose onto the other end of the adapter. Turn the vac on before you start to sand.
Bosch ROS20VSK Dust Collection FAQ
What size is the dust port on the Bosch ROS20VSK?+
The port is round and about 28 mm at the outside. That number comes from an adapter made for this sander, not a Bosch spec sheet. The inside size is not confirmed, so measure your own port with calipers before you buy.
Does the Bosch ROS20VSK work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose is much wider than the Bosch dust port. The GulpDust PETG adapter fits the tool port on one end and your vac hose on the other.
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.
