Tuning Avenger gauge thread size

[utah300rum]

I would like to upgrade my Avenger gauges to something easier to read. I have seen some gauges with a scale that goes further around the face to have a longer scale.

Anyine upgrade theirs or know for sure what the thread size is?

Thanks

When there's gauges that are hard to read I dab a dot of fluorescent nail polish color at the max fill needle point on the outer glass and on the refill point mark where the needle points to use a different color.

Good to mark the sweet spot too like 3000psi for example.

I've seen the question come up before, but no definitive answer. I suspect they are like the Liberty, which is 8mm straight thread. They may have changed them to M10, but very unlikely 1/8" BSPP or NPT. If no one chimes in, the next time you degass, remove one to inspect.

Most/many of the gauges in this size are not accurate, regardless of scale. Options in the states are very limited for M8 or M10,
