CA17672N FUEL CAP

The **Fuel Cap CA17672N** is a thermos-type fuel tank cap designed for certain piston-engine aircraft fuel systems (notably for selected models of the Piper PA-23 / PA-23-160 series). It features a fuel-resistant elastomer seal formulated to resist swelling, and a robust lever mechanism engineered to prevent bending or cracking. The cap is vented to allow fuel tank ventilation, while maintaining a secure seal under normal operating conditions, providing reliable fuel-system integrity and safety during operation and refuelling. --- ## Applications - Replacement fuel cap for compatible Piper PA-23 and PA-23-160 aircraft models requiring a vented thermos-type cap - Refuelling operations where a secure, fuel-resistant, PMA-approved cap is needed - Maintenance or overhaul of fuel tank filler interfaces on eligible aircraft to ensure sealing integrity and venting compliance --- ## Why CJ Aerospace?
