Dust Collection Fittings, Elbows, Wyes, Tees, and Couplings

Dust collection fittings are the parts that connect and route your duct. Elbows turn corners, wyes and tees split one line into two, and couplings join two straight pipes. Together they shape the path your dust travels from the tool to the bin.

A wye splits the line at a gentle angle, while a tee splits it at a sharp 90 degrees. The gentle angle of a wye keeps the air moving with less drag, so you lose less suction. Use a wye when you can and a tee when space is tight.

Match the fitting to your duct size. Most shops run 4 inch main lines and 2.5 inch drops to the tools. Measure your pipe, then pick the fitting in that size. Pick a type above to see every size.

Yes. We make fittings in 4 inch and other standard sizes from 1-1/4 inch up to 4 inch. Pick a type above to see every elbow, wye, tee, and coupler we offer in each size.

In most setups, yes. Each end is printed to a standard duct size, so it pushes on and grips on its own, and the joint holds well enough to keep your suction strong. Add a wrap of tape at any joint that sees heavy use.

We print every fitting ourselves, so a size only goes on sale once we know we can make it and what it costs. A few of the biggest ones do not come out in one piece, and a few need a second part we do not make yet. Those pages say so and take your email instead of your money.
