Tuning AEA Challenger .45 pup air gauge.

[Quad82]

Looking to purchase a new 5000 or 6000 psi Air tube gauge for my Challenger. I believe it’s a 28 mm gauge. The stock one is off by 300 to 400 psi. I ink marked a line at 3000 psi for reference while hooked to my fill station using 4” wika gauges. But I want to buy a better gauge that I can read. I like the looks of Talon Tunes gauge. But wasn’t sure of the thread and pitch size. I measured the threads being just shy of 8mm across. They look to be a straight thread and not tapered. The gauge also uses a white, flat seal at the bottom of the end cap. It was mushed and somewhat sealing the gauge hole. I replaced it with a new seal. Any info would be appreciated. Thanks Darrell

AFAIK AEA uses non standard gauge threading. One of the pain points of owning them. Maybe reach out to Bin at the pellet shop and see if he has any alternatives for you.

The gage on my Impact seals like that. It is BSPP. I bought a digital gage from Edgun West. There some nice digital gages made now that should work well with the air cylinder.

Take the gage to a hardware store and the nuts and bolts department can measure it to the correct size.

Thanks. I thought it was British. I will look into the Edgun West site. I was looking at the Orcair digital ones. But I seen a lot of mixed reviews. But at $40, I might take a chance.

I have the hardware type place card readers. I forgot about using them. Thanks

It's a M8 size...the aea groups I'm in haven't really been able to find replacements. Seems any m8 sized are mpa based gauges.

I measured the threads being just shy of 8mm across.

I did order the Orcair digital gauge. It’s a 1/8 bssp male thread. I also ordered a 304 SS 1/8 bssp female to m8x1 male adaptor. The Challenger has a gauge cover that will still cover most of the gauge if I have to use the extended adaptor. If they don’t work out, I have a few other guns that have different thread types. So maybe I will use it elsewhere on one of them.
