A three-way bulkhead tee in SUS303 stainless with AN3 connections, combining two jobs in one fitting: it splits a line into two branches and anchors that junction solidly to a panel at the same time. The classic use is a brake line splitting to left and right rear calipers at a chassis-mounted point, where a floating tee hanging on three hoses would be both untidy and a fatigue risk. Mounting it through the panel with a bulkhead nut means the fitting is properly supported and the hoses simply carry fluid. AN3 is the standard brake and clutch line size. Stainless resists corrosion in the exposed underbody positions these tees usually occupy.
