Vibrant Performance AN Fittings & Adapters

Vibrant Performance AN fittings on this page connect fuel, oil and coolant lines on custom and performance builds. They are sold by AN size, thread type and tube size, not by vehicle.

The range includes male and female AN adapters, tube to male AN and tube to female AN adapters in 45 and 90 degree versions, AN to ORB flare adapters with an O-ring, AN to inverted flare adapters, flare unions with an NPT port and PTFE washers for bulkhead fittings. Sizes run through values such as -4AN, -6AN, -8AN and -10AN, and brass olive inserts are listed for the tube adapters.

To choose, start with the hose or tube you are using. An AN size describes the thread and the line size it connects. A tube adapter must match both the AN size and the tube outside diameter. The angle matters when space is tight: a 45 or 90 degree adapter lets the line turn in a short distance. Check the thread type at the other end too, since NPT, ORB and inverted flare are not interchangeable.

There is no vehicle list for these parts, so read each title and the product page details for the size. For other fittings and lines, see the full AN Fittings & Adapters range. Priced in Canadian dollars and ships across Canada.
