2 in. (50.8mm) Dust Port Adapter: Measure Yours, Build to Your Number
GulpDust prints dust collection adapters in PETG to the numbers you give us. This page is for one case: you put calipers on a dust port or a hose end, and the number was close to 2 in. (50.8mm).
Your reading may be a little over or a little under 2 in. (50.8mm). That is normal. Enter what you measured and we build to that number. Made in the USA.
Build an adapter to the number you measured
Measure both ends, enter your two numbers, and we print the part between them in PETG. Made in the USA.
How to measure your port
Use calipers. If the port sticks out, measure across the outside. If the port is an opening, measure across the inside. If it is a hose cuff, measure the cuff where the adapter will sit.
Write down the number your calipers show, not the number printed on the tool or the box. The size guide shows where to put the jaws.
What you can order at 50.8mm
If your calipers read about 50.8mm, the builder prints that end of the adapter to the number you enter. We do not guess a size from a tool name, and we do not round your number to a standard size. Fit depends on your measurement, so measure twice.
Parts we sell with this size in the name.

What does 2 in. mean on a hose or duct?
2 inches is 50.8mm. It is a common name for hoses and duct.
A hose sold as 2 in. can read a little different on the cuff you connect to. The name on the package is not a reading. Measure the cuff or the port yourself.
Inside or outside of the cuff?
Hose and duct sizes are often named by the inside. A cuff you slide an adapter into is measured on the inside. A cuff you slide an adapter over is measured on the outside.
Tell the builder which one you measured, and the part is printed to that number.
Questions about a 50.8mm reading
What size adapter do I need for a 2 in. (50.8mm) port?
One built to your own reading. If your calipers show about 2 in. (50.8mm) across the part you connect to, enter that number in the builder and we print that end to it. Measure the other end too, so both ends are right.
Is 2 in. (50.8mm) the inside or the outside?
It depends on what you measured. If you measured across an opening, 2 in. (50.8mm) is the inside. If you measured across a stub that sticks out, it is the outside. Tell the builder which one you measured, and do not guess from a name on a listing.
Is my hose 2 in.?
It might be. A hose sold as 2 in. can read a little different on the cuff you connect to. Measure your own cuff with calipers, and enter the number you see instead of the name on the package.
Can I find my tool on this page?
No. This page does not list tools. Port sizes change between makers and between models, and a tool name does not tell us what your port measures. Put calipers on your own port and enter that number.
Do I need clamps or tape?
Sometimes. We print each end to the number you enter, so a joint can push on snug. A joint that sees heavy use may still want a wrap of tape. Check the joint after your first few minutes of use.
Do you sell the design file?
No. We sell the finished part. Each adapter is printed to order in PETG and ships from the US.
