yeah, the last 6 pack i bought was way back in 2020 and was 05. No difference as far as I can tell though. I like the gasket on these, seems to be P style gasket. The 6 pack I bought didnt come with washers and was a few bucks cheaper. This was from Build quality is great, so if it aint broke... https://www.ebay.com/itm/253285524894
Seems cheaper on amazon now though.
