I just purchased the OMS O2 clean regulator for an advanced deco course. I want to add a small SPG to the HP port on the first stage.

Do I need to change out the O-ring on the SPG to make it 02 compatible?
Are these small SPG’s O2 clean?

I have had one on my OMS O2 reg. for 10 years. I think I swapped out the original nitrile, or buna for a Viton ring. Bad things about the gauge is that it is nearly impossible to read without a magnifying glass.

Take a look at this one from Scubatoys.

I have a few and love them. They are the same as the Suunto for 1/2 the price. Scubatoys will also swap out the long hose for a 6" if you ask nice. A little more expensive than what you were originally looking at, but well worth it IMO.
