It may depend on whether it was sold for auto use or fixed refrigeration.

It's the exact same R-134a inside the bottle, only the fittings are
changed to increase the prices...

Adapters between SAE Flare and ACME Flare are readily available
premade at any refrigeration supply house, for a lot less than it
costs to make them. I have them.
