Infinity Tools 4" Y-Fitting

It serves as a 45° inlet for a 4" hose into a 4" hose run, letting you branch an additional tool into your main dust collection line. See more dust collection fittings.

The branch inlet is angled at 45 degrees, which smooths the transition so air and debris flow into the main run without hitting a sharp corner.

Both the main run and the branch are sized for 4" hose. Find compatible hose in our hoses and accessories collection.

A 45° inlet eases airflow into the main line, reducing turbulence and helping maintain suction compared with a sharp right-angle junction.

Yes. The Y-fitting is designed to branch a second 4" hose into an existing 4" run, which is exactly how you expand a single hookup into a multi-tool system. Explore the full dust collection range.

This version branches a 4" hose into the main run, while the 4" x 2-1/2" version accepts a smaller 2-1/2" branch. Choose based on the hose size of the tool you are connecting.

Add hose clamps from our hoses and accessories selection to secure each hose to the fitting for a tight connection.

Install it at the point where a second 4" hose needs to merge into the main trunk line, typically where the branch heads toward an additional machine.

Yes. It works with standard 4" hose and custom ductwork. Browse our dust collection fittings for the rest of the connectors you need.

The 45° design minimizes airflow loss at the junction, but overall suction across multiple tools still depends on your dust collector's capacity and the use of blast gates to direct airflow.
