Billet Y 3-Way Fitting FAQ
What hose size does this fit?
This fitting is sized for 3/4" barb hose on all three ports.
How is this different from the T fitting?
Both are 3-way fittings for 3/4" barb hose. The Y fitting's angled ports suit smoother flow-splitting layouts, while the T fitting's perpendicular port suits tighter packaging.
Do I need clamps to install this?
Yes. Use appropriately rated hose clamps on each barb connection to secure the hose and prevent leaks under pressure.
What's it made from?
304L stainless steel construction with an aggressive barb design, built to hold up in demanding automotive environments.
Will this restrict flow compared to a straight fitting?
No. The internal passages are designed smooth to minimize turbulence and maintain optimal flow rates through all three ports.
