Looking for help to determine if my 90 fitting is HP or LP

[OCDiver]

I'm looking to add a high pressure 90 fitting to my RAS SPG hose. I have the pictured fitting. I don't know how old it is but I've had it for a long time.

Can anyone tell if it's HP or LP based on the pictures? The hose does screw into a current 1st stage HP port and I do know that it's a HP hose. All of the threads (both sides of hose and both sides of fitting) are the same.

I’m gonna take a wild guess here: besides the thread size, I think LP and HP versions would have the same design

I have a couple of each (that look the same on the outside), I could try and open them up to confirm

Does a spool fit into the male side? If so I would expect that given it is 7/16-inch and fits the mini SPG that it is HP.

I'm afraid I don't know what a spool is.

if its 7/16 its HP

the internal design is visually identical between most hp and lp swivels so without a micrometer its hard to tell from pictures

there's no spool in these HP swivels anyway so dont stress it

Here's something that I can work with. I'll confirm whether or not it's 7/16. - Thanks.
