Um... shouldn't an SPG go to a high pressure port?

I keep some plugs of each size in my Save-a-Dive kit. They come in handy from time to time.
 
I get a loaner from my LDS, and it's pretty ancient but... it connects to a low pressure port. WTF? I thought this would have to go to a high pressure port!? What's up with this?

You might look into a new LDS. I'm surprised the shop would make this mistake.

I wouldn't get down on them too much, the person giving the loaner was probably born after the change was in place and may not even be a tech. "you need a loaner, here is a loaner." Good customer service, bad knowledge base.

Since the LDS did not put the SPG on, the "tech" who was installing it would be resopnsible for the knowledge of his equipment.

All this is easy for me to say 'cause I was around during the change and still am using old gear with and without adaptors.

There is no problem that can't be solved with a liberal application of sex, tequila, money, duct tape, or high explosives, not necessarily in that order.

No, that wasn't the case. But, on my part it was a last minute, "Whoops, someone needs X, too," so I take part of the blame. Someone was trying to do me a favor. I should have been smart and just rented a full reg setup.

I love how a simple little question has taught at least a few of us a lot of little tidbits. I love you guys, thanks!
 
Up until the late 60s or early 70s both LP and HP ports on regs had the same 3/8x24 threads

Later than that in some cases. The first Sherwood Brut we got new in 1985 had all 3/8" ports. Still have it, with an adapter. The Sherwood Magnum we got at about the same time had the larger-diameter HP port.
 
You might also encounter some older European regulators with British Standard pipe threads, often mistakenly referred to as "metric threads." You can get adapters for those also.
 
I have a DACOR 900 1st stage, dated mid 80s.
All LP and HP ports have the same 3/8 ports. Every port has a label stamped in the metal LP or HP.
New HP hoses come with 7/16 threads, so you need an adaptor.
You can find them in Divers-supply, Leisurepro or Scubatoys.
For your case you need the AA51 adaptor for female 7/16 to male 3/8. The cost is around 6 US$.
