Modern vehicles commonly follow the SAE J2044 standard for quick connect fittings in applications such as air breather lines, vacuum lines, PCV lines, coolant lines, and Electronic Fuel Injection (EFI) fuel lines.

These OEM style female SAE J2044 quick release fittings will connect to male J2044 quick connect barbs and adapt them to a hose barb for use with rubber hoses.

Fuel systems commonly use the 5/16" and 3/8" size quick connect fittings. Most GM vehicles use M10 (9.89mm) quick release fittings for PCV breather lines. Ford and Dodge commonly use the 5/8" (15.82mm) quick release fittings for PCV breather lines. Measure your fittings to confirm the exact size needed before ordering.
