The Nitrous Express filtered 8AN ORB to 4AN flare fitting is manufactured for the inlet side of the Lightning 375 N2O solenoid. This filtered ORB-to-flare adapter provides filtration while converting between 8AN ORB and 4AN flare interfaces, helping protect the solenoid inlet from particulates and ensuring proper mating between the solenoid and plumbing on Lightning 375 installations.
