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. Use the size filter above to narrow the list.

Yes. We make fittings in 4 inch and other standard sizes from 1-1/4 inch up to 4 inch. Pick your size in the filter to see every elbow, wye, tee, and coupling we offer in that diameter.

Yes. Each end is a friction fit printed to the exact pipe diameter, so it grips on its own. You skip the tape and the hose clamps, and the joint still seals well enough to keep your suction strong.

Most smaller fittings print on a standard bed like a Bambu Lab P1S. Larger fittings need a bigger printer. Each fitting lists its print class, so you can match the part to the printer you own before you buy the file.
