Performance Fittings Y Adapter Fitting -4 AN to Dual -3 AN, Blue - PRF6243

The Performance Fittings Y Adapter Fitting (PRF6243) splits a single -4 AN line into two -3 AN lines (or combines two -3 AN lines into one -4 AN line), using a compact cast Y-shaped body. Manufactured from durable aluminum and finished in blue anodized coating, this fitting provides a secure, leak-free connection for demanding automotive and racing fuel, oil, or coolant systems.

Common uses include splitting a single fuel supply line to feed dual carburetors or dual fuel rails, or combining dual return lines back into one. The 37° AN flare seals metal-to-metal on both ends without requiring thread sealant, and the fitting can be removed and reinstalled without damage.
