Are these the correct F Body A/C hoses for serpentine R4 conversion?

We have the stepped style washers on my brother's Camaro. They came with the Delco compressor. Five years later or more and thankfully, no issues.

They work sometimes and sometimes they don't. Just saying it's best to maintain continuity between the compressor and fittings for best results. 🙂
