CA27221N FUEL CAP

The **Fuel Cap CA27221N** is a thermos-type, non-vented fuel tank cap designed for certain piston-engine aircraft. It features a fuel-resistant elastomer seal to resist swelling and a robust lever mechanism engineered to prevent bending or cracking. The cap provides a secure closure for the fuel tank filler neck, ensuring fuel-system integrity and safe refuelling operations. --- ## Applications - Replacement fuel cap for eligible aircraft using Piper PA-24, PA-30 or PA-39 series (as listed under CA27221N eligibility) - Refuelling operations where a secure, non-vented cap is required - Maintenance or overhaul of fuel tank filler interfaces on eligible aircraft to ensure sealing integrity and compliance --- ## Why CJ Aerospace?
