Twisted Choppers Octane Vented Gas Cap With Weld In Bung

Twisted Choppers Octane Vented Gas Cap With Weld In Bung

The Twisted Choppers Octane gas cap delivers a clean, low-profile look on any custom gas tank where a conventional screw-on cap falls short. Its weld-in bung design gives full control over cap placement, making it the natural choice for builders working on bobbers, choppers, and hardtail Sportsters.

Key Features

• Streamlined aluminum cap designed for custom gas tank applications
• Weld-in steel bung installs in a 1-9/16″ hole for a secure, flush-mount fit
• Vented with an o-ring seal to prevent pressure buildup
• Gas pump nozzle fits inside the bung for easy filling
• Available in Black and Polished finishes
• Made in the USA

Fitment Notes

• Requires welding the steel bung into a custom gas tank; not a bolt-on replacement for OEM-style caps
• Bung requires a 1-9/16″ hole in the tank; thread size is 1-3/8″-12, larger than the Micro Spike and Micro Flat bungs; verify compatibility before ordering
• Suitable for bobbers, choppers, hardtail Sportsters, and any custom application requiring a vented cap
• Review available finishes: Black and Polished, and select the correct variation before ordering
