The Texas Speed 3AN Swivel Nut Flare Cap seals an open -3AN male flare fitting with a cap that uses a swivel nut. Because the nut turns independently of the cap body, the cap can be tightened without twisting the body against the flare seat, which is the same arrangement used on AN hose ends. It is used to close off an unused port, tee or adapter on fuel, oil or coolant plumbing, or to keep a fitting clean while a line is disconnected.
Texas Speed machines its flare caps and plugs from 6061 aluminum to tight tolerances and black anodizes them for corrosion resistance. They are lightweight and durable, and they are compatible with most fuels, solvents and oils. This -3AN swivel nut cap is sold individually. Texas Speed also offers a standard one-piece 3AN flare cap and a 3AN flare plug in the same finish.

FAQ
What does the Texas Speed 3AN swivel nut flare cap do?
It threads onto a -3AN male flare fitting and seals it, closing off an unused port, tee or adapter so it does not leak and so contaminants stay out of the system.
How is a swivel nut flare cap different from a standard 3AN flare cap?
On the swivel nut version the nut rotates separately from the cap body, so tightening the nut does not spin the body against the flare seat. The standard Texas Speed 3AN flare cap is a one-piece cap. Both seal the same -3AN male fitting and are black anodized 6061 aluminum.
What is the swivel nut flare cap made of?
Texas Speed machines the 3AN swivel nut flare cap from 6061 aluminum and black anodizes it, which resists corrosion from fuel, oil and the elements while keeping the part lightweight.
Is this cap safe for fuel and oil systems?
Yes. Texas Speed states its flare caps and plugs are compatible with most fuels, solvents and oils, so the -3AN swivel nut cap can be used on fuel, oil and coolant lines.
Is this a universal part?
Yes. The Texas Speed 3AN swivel nut flare cap is not vehicle specific. It fits any standard -3AN male flare fitting regardless of the vehicle or engine.
