Perko Spare Gas Cap w/O-Ring & Cable

The Perko Spare Gas Cap with O-Ring and Cable is a replacement fuel cap designed for marine and outdoor power equipment applications where dependable sealing and tethering are essential. This black polymer gas cap features an integrated O-ring for watertight sealing and a cable attachment point to prevent loss during operation or transport. The cap's construction addresses a critical maintenance need for boat owners, ATV operators, and users of small engines exposed to moisture, vibration, and dynamic conditions where standard caps are prone to failure or separation.

The O-ring gasket creates a fuel-tight seal that prevents vapors from escaping during storage and operation, reducing spill risk and odor. The cable tether, secured between the cap's attachment holes, eliminates the inconvenience and safety hazard of a missing cap—a common problem when fueling in rough water or remote terrain. Perko's design balances simplicity with functional reliability, using polymer construction that resists corrosion from saltwater exposure and fuel contact. This spare cap is particularly valuable for marine users operating in coastal environments where metal caps deteriorate rapidly, and for any operator who has experienced the frustration of a loose or lost original cap.

Keeping a spare Perko gas cap on hand is practical maintenance strategy for boat owners, recreational vehicle operators, and equipment users relying on portability and reliability. Whether replacing a damaged original or maintaining a backup for offshore operations, this cap ensures your fuel system remains secure and sealed. The compact dimensions and minimal weight make it easy to store in a toolbox or cabin locker for field service or emergency replacement.

Perko is recognized throughout the marine industry for fuel system components and deck hardware engineered to withstand continuous saltwater exposure and demanding operational conditions. This spare cap maintains Perko's standard for fit, function, and durability across their fuel cap and tank ventilation product line.
