RaceFlux SAE J2044 Female Quick Connect Blanking Cap

Seal off an unused quick-connect nipple: this OEM-style female SAE J2044 blanking cap clicks onto any male J2044 tube and dead-ends it, with a built-in FKM (Viton) O-ring preventing leaks. The clean fix when a PCV reroute, EVAP delete, or fuel system change leaves a factory nipple open.
