Size help
Measure your hose or duct first, in inches or millimeters. Our measuring guide shows how.
Common questions
Will it fit my duct?
It is sized for 6 inch duct with a 3-1/2 inch branch. Every opening on it is printed to those numbers.
Do I need clamps or tape?
The joint holds on its own in most setups. For a joint that sees heavy use or pulls high suction, a wrap of foil tape locks it down.
What is it made of?
PETG, the same plastic on every part we make. Our About page says why.
Do you sell the design file?
No. We sell the finished part. We print it to order and ship it to you from the US.
