27mm 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 27mm.
Your reading may be a little over or a little under 27mm. 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 27mm
If your calipers read about 27mm, 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.
We do not list a stock part at this size. The builder makes one to your number.

What does 27mm mean on a dust port?
27mm is about 1.06 inches. You may also see it written as 1-1/16 in., which is 26.99mm. The two names point at nearly the same number.
A size on a box or a listing can be the inside of a port, the outside of a port, or only a name for a size. If you are not sure which one it is, measure your own port with calipers.
Close to 27mm is not the same as 27mm
If your calipers read 26.6mm on one port and 27.4mm on another, the two are 0.8mm apart. On a snug PETG joint, that gap can matter.
That is why the builder asks for your number and does not round it. Enter what your calipers show, to a tenth of a millimeter if you can.
Questions about a 27mm reading
What size adapter do I need for a 27mm port?
One built to your own reading. If your calipers show about 27mm 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 27mm the inside or the outside?
It depends on what you measured. If you measured across an opening, 27mm 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.
Can I use a regular shop vac hose with a 27mm port?
Often with an adapter, yes. Many shop vac hoses are much wider than 27mm, so a stepped adapter joins the two. Hose sizes vary by maker, so measure your hose end as well and enter both numbers.
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.
