Anyone else seen an aluminum AN fitting like this? I bought some at my local aircraft supplies store (B&B), and they are supposed to be the same as the regular blue ones. It is even stamped with an "AN 818" on the side.
I understand that these particular pieces came from McDonnell Douglas. I was told the reason they are anodized a different color is that they are used in oxygen fittings. The different color anodizing is apparently done, as they have different sterilization requirements (i.e. they are kept cleaner).
Wondering if anyone else has seen or can confirm this understanding (curiosity).
Thanks,
Scott
