How It Works?

More Than Just a Shiny New Fuel Cap…

The Leak Defender® is a 2-piece fuel neck adapter…

Consisting of a collar, which replaces your old fuel neck, and a cap.

Creates a Completely New Sealing Surface…

The Leak Defender® collar has an O-ring underneath which seals to your existing fuel neck when tightened and is securely fastened with set screws. It is sealed along the outer perimeter, away from the inner perimeter which is prone to wear and tear from everyday fueling.

Made with the Strength of Billet Aluminum…

The Leak Defender® fuel cap twists onto the collar, your new and improved sealing surface which is built to last…made with the strength of billet aluminum.
