O-ring and SPGs

[Akimbo]

It really doesn't matter which O-ring on an SPG fails since all regulators less than about 30 years old have the same tiny flow restricting orifice in the HP port.

My first question was when was it last serviced? I've seen lots of people dive with champagne bubbles on gear obviously not getting around to changing the O ring before it gets too late (not suggesting you have done so)

In my experience 90% of gear failures is from lack of preventative maintenance and as mentioned above spools are often ignored. I ghave all my O rings changed on an annual basis

I found my HP hose to my dive computer console started to emit champagne bubbles during a week-long diving trip. It didn’t change my diving profile much during the whole week of diving. I just replaced it when I was back home.

Yes, it was the o-ring between the hose and SPG. Thank you for the video.

That would be the spool which is probably the most neglected connection on a reg set. Water get into the connection and takes forever to dry out. That leads to corrosion. I have actually seen spools break in two because of the corrosion seizing the spool. Take the SPG off the hose, clean it up, replace with a new spool that is well lubed.
