Interesting phenomenon was discovered recently on stock stainless pitot tube. The anodized aluminum insert is delaminating. Wondering what's the cause? Vibration, galvanic corrosion or a defective part? Any advice on preventive maintenance?

If any builders have pitot tube not mounted could you please check if the fitting makes the bend? Or should I order new tube. The part was and still is working flawlessly for 2,500 hours. Was tightened once in Phase 1.
