Ridgid R4518 Table Saw Dust Port Size and Vacuum Adapter Guide
The Ridgid R4518 is a 10 in. portable table saw. A table saw throws the heaviest chip stream of any tool in the shop. Rip one sheet of plywood without a hookup and you will spend more time sweeping than cutting.
The saw has a round dust port at the rear. The inside is 57.15 mm, which is 2-1/4 in. The outside is 63.0 mm. A 2-1/2 in. shop vac hose feels close on that port, but close is not sealed. It leaks right where the saw makes the most dust. A GulpDust PETG adapter is printed to this exact port on one end and your hose on the other end, so the joint seals and the chips go into the vac. No tape. No clamps.

Ridgid R4518 Dust Port Size: 57.15 mm Inside, 63.0 mm Outside
The rear dust port on the R4518 is round. The inside measures 57.15 mm, which is 2-1/4 in. The outside measures 63.0 mm. Both numbers come from a printed adapter made for this saw, so you can trust the fit.
Most shop vac hoses are 1-7/8 in. or 2-1/2 in. Neither one seals on a 2-1/4 in. port. The 2-1/2 in. cuff slips over the port and wiggles, so dust blows out the gap on every rip cut.
A GulpDust adapter is printed to grip this exact port on one end and your vac hose on the other end, so the suction stays at the blade instead of leaking out the joint.
This saw sits in the 57 to 58.4 mm port family, the 2-1/4 in. group shared by several jobsite table saws. Ports can vary by model year, so measure your saw to confirm before you buy.
How to Connect a Shop Vac to the Ridgid R4518
Unplug the saw first. Then wipe the sawdust off the rear port, so the adapter seats clean and seals all the way around.
Press the saw end of the PETG adapter onto the port. It is a friction fit, so a firm push is all it takes. Then press your shop vac hose onto the other end.
Turn the vac on before the blade touches wood. A table saw fires chips down through the blade slot from the first inch of the cut, so the vac needs to be pulling the whole time.
Dust Collection for a Portable Table Saw
A portable saw moves between the garage, the driveway, and the job site. Every one of those spots is a bad place to spray sawdust, so the hookup has to travel with the saw.
The PETG adapter is small and tough, so it rides in your kit without cracking. Push it on when you set up the stand and you are cutting clean in seconds.
If you rip a lot of stock, add a cyclone separator between the saw and the vac. The heavy chips drop into a bucket, so your vac filter stays clear and the suction stays strong through the whole job.
Ridgid R4518 Dust Collection FAQ
What size is the dust port on the Ridgid R4518?+
The rear port is round. It is 57.15 mm on the inside, which is 2-1/4 in., and 63.0 mm on the outside. Both numbers are verified against a printed adapter made for this saw.
Will a 2-1/2 in. shop vac hose fit the R4518 port?+
Not by itself. The hose cuff sits loose on the port, so it leaks and drops off mid cut. The GulpDust PETG adapter grips the port on one end and your hose on the other, so the joint seals tight.
Do I need clamps or tape to attach the adapter?+
No. The adapter is a friction fit. You push it on and it holds, so setup takes seconds and packs away just as fast when you fold the stand.
Does the same adapter fit other Ridgid table saws?+
Maybe. Some Ridgid saws use a port near this size, but ports vary by model and model year. Measure your port before you buy so the fit is tight.
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, so the part stays stiff and shrugs off shop heat.
