These special Y fittings split flow at 45° angles to present less flow obstruction than standard 90° T fittings. The large inlet / small outlet configuration also lets you run a larger supply line to the fitting and split off into two smaller lines for optimum flow.
The two outlet ends are both male, while the inlet is a female swivel nut. All three are AN-type fittings (SAE UNF threads, 37° flare) that conform to JIC and SAE specifications. Anodized aluminum construction is suitable for fuel and oil systems. Sold individually.
