Infinity Tools 4" T-Fitting

This is the third one I’ve bought to expand my dust collection lines, and the tapered leg slides into the hose without any wrestling match with clamps. Airflow through the straight section is noticeably better than my old Y-splitter.

The angled leg makes it easy to direct airflow without kinking my main hose, and the smooth interior seems to reduce dust buildup. Installation took about 30 seconds since it slides right into standard 4” ducting.

My old setup had gaps everywhere, but this 4" T-fitting locks into the hose line with zero leaks. The airflow direction marking on the leg is a thoughtful touch that saved me from installing it backwards.
