Perko Spare Cap with Chain Cover Cap

PERKO Spare Cap with Chain Cover Cap for Marine Fuel Systems

Ensure the safety, integrity, and performance of your vessel´s fuel system with the PERKO Spare Cap with Chain Cover Cap. Expertly engineered for the demanding marine environment, this premium fuel filler is the ideal replacement or upgrade for boat owners who prioritize reliability and durability. Moving beyond a simple cap, this component is a comprehensive solution designed to offer peace of mind and seamless operation every time you refuel.

The primary benefit of this PERKO unit lies in its robust construction and advanced safety features. Crafted for longevity, the cap is made from chrome-plated bronze, providing a brilliant, polished finish that resists the corrosive effects of saltwater and sun, maintaining your boat´s pristine appearance. This is securely tethered by a stainless steel bead chain to a rugged black polymer body, a design choice that prevents the frustrating and costly loss of a fuel cap overboard. This thoughtful feature ensures your cap is always right where you need it.

Safety is at the core of its design. This is not just one of many standard cover caps; it incorporates an integral tank vent complete with a vital flame arrestor. This critical safety mechanism is designed to prevent external flames or sparks from igniting fuel vapors within your tank. Additionally, an integrated anti-surge valve effectively mitigates fuel splash-back, which can occur from rough seas or during the refueling process. This keeps your deck clean, protects the environment, and prevents dangerous fuel spills. The angled neck design further enhances convenience, allowing for easier and more direct access for refueling nozzles and reducing the risk of spillage.

This comprehensive kit includes everything needed for a secure, leak-proof installation, including a fresh O-ring to guarantee a tight seal and a deck plate key for easy opening and closing. Trust in the PERKO legacy of quality to protect your investment and ensure your boat´s fuel system is sealed, safe, and secure.
