Is this defective, or some new sort of can design that requires a side tap or something else?

I haven’t messed with a small can of 134a in years. I know they make the ones with stoppers in the top, but that’s not this…
 
That's interesting to say the least, looks like they forgot the threads on that can. Show us a picture of the entire can. Thanks.

I wonder if this is r410a?

I know the old r12 automotive refrigerant cans had a top without any nipple at all the piercing adaptor attacked to the rounded off lip at the top of the can and gripped that.

I don't think R410a is ever sold in small cans because the ORM shipping rating of that type of can doesn't allow the higher vapor pressure of R410a.
I noticed that the smallest size it is avail in is a 24 ounce container that looks like something liquid propane might come in.
 
I still have a couple of older side can taps from when they didn't put the threaded tops on the cans.
Must be R12 Artic Air? lol

We used to use that all the time at the local Honda store when installing AC kits into many Accords and Civics back in the mid late 1980s.

The can tap would grip the rounded lip and seal there.
 
Honestly I was wondering why the side taps stuff even existed. Now I know.
That's all you say prior to r134a for the most part when charging with r12. The cans had no threaded nipple style ports,
Just the rolled aluminum lip that the side tap adaptor clamped onto with a seal inside of it to mate with that rolled lip.
There were a lot of good aspects to r12, especially since you could use a clear sight glass usually located in the receiver dryer to fill with refrigerant properly, as you added r12 you watched the sight glass while the compressor was running, when the bubbles disappeared you were correctly filled + or - an ounce or so.

It seems like I remember that some of the early R134a cans didn't have the threaded tops either. I still have three cans of R12 on the shelf that would have to take the old style connector or a side can tap.
