Ridgid R8606B Random Orbit Sander Dust Port Size and Vacuum Adapter Guide
The Ridgid R8606B is the 18V brushless 5 in. random orbit sander. It runs on the Ridgid 18V battery. 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.
The sander has a round dust port on the side. The inside of that port is about 36 mm. That number comes from a shop vac adapter made for this sander. The outer size is not confirmed yet, so measure your own port with calipers before you buy. A GulpDust PETG adapter is sized to the port on one end and your shop vac hose on the other end. No tape. No clamps.

Ridgid R8606B Dust Port Size: About 36 mm Inside, Round
The dust port on the R8606B is round with a tapered nub. The inside measures about 36 mm. That figure comes from a third-party shop vac adapter made for this Ridgid sander, so treat it as a starting point, not a hard spec.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. They do not fit a 36 mm port on their own. That gap is why 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 Ridgid R8606B Dust Port
Close caliper jaws around the OUTSIDE of the port nub. 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 Ridgid R8606B
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.

What size is the dust port on the Ridgid R8606B?+
The port is round and about 36 mm on the inside. That number comes from a shop vac adapter made for this sander. The outer size is not confirmed, so measure your own port with calipers before you buy.
Does the Ridgid R8606B work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose is wider than the sander dust port. The GulpDust PETG adapter fits the tool port on one end and your vac hose on the other.

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.
