Hatsan WHAT thread is the pressure gauge socket on the Hatsan H class tubes.

Both for the reducer bushing ID AND OD. I'd like to just find a manometer that's not $56. I'm sure hatsan isn't the only entity to ever produce a manometer of this thread size.

I'm guessing m18 or m16. I don't have my caliper or rule on me.

Best I could come up with is a male to male m16-1.0 to NPT
Then you would need NPT male to female
Which makes for an ugly hook up.
Plus I don't know the pressure rating for the adapter...

Thanks budro, but i'm a tard, the "1/8bsp" i thought i was trying was an NPT. the BSP fits inside the adapter bushing. Just need to order a new one. But man, Hatsan with those H-Class and AT44/BullBoss/Trophy tubes and their stupid monster thread gauges you cant source ANYWHERE else. Thanks any way bro man.

TBH, better than what i was using.. The only BSP fitting i had was a male foster QD, which i had hooked to a female with an NPT female thread on the other side, with an NPT gauge... LOL. Function over fashion, so you can understand why i want the proper gauge.
