Raceflux M10 SAE J2044 Female Quick Connect Blanking Cap

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 caps are designed to seal off unused male J2044 quick connect barbs. Includes a built-in FKM rubber O-ring to prevent leaks.

To determine the size needed, measure the outer diameter of the mating male barb and refer to the diagram below.

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.
