Anyone know where I can find a replacement manometer for the AT44-10? I just discovered a leak in mine & they say it cant be repaired, the entire gauge incl. housing has to be replaced. I'm having trouble finding it on-line. Any help would be really great. Thanks

It might be a "standard" size gauge- meaning an industrial supplier might be able to obtain one that is usuable. The gauge is in the head/end of the reservoir tube (w/valve), correct?

I saw a photo once, and IIRC, the gauge is smaller than the standard 1" gauge that is common, and it has a brass sleeve around the threads to mate up with the female threads in the end of the air reservoir.... ie an adapter.... I don't know what size the threads on either the gauge or the adapter are, however.... You need to grind a socket so a very thin wall (the example I saw actually cracked) to get the gauge out of the recess in the end of the reservoir.... This gauge failure seems to be relatively common on the Hatsans.... ie it is NOT a rare occurence....

Correct. It screws onto the reservoir & the gauge is in a recess at the end with the fill port just below it. Any ideas where i might find one?

I got the gauge out and the seal behind t is fine, so I know its the gauge itself at fault. I still cant source a replacement for it though. I really need this thing fixed. Anybody know where I can find one?

I really don't know the thread size on it. I have no tools to measure it. This thing has me really stressed.

Here is a place that specializes in mini guages

Measure the OD for a start

Worst-case scenario: you have to buy a replacement tube/valve assembly in order to get your rifle operational, then go looking for a gauge at your leisure (and be sure to tell everyone else where/what you found!).

There was some new "Hatsan USA" location a month or two ago- perhaps try them for replacement parts? Sorry, don't have the website url handy...

Thanks for the link SMP. It looks like that company in the UK has the gauge to fit. Now its just for me to measure mine to make sure it will fit.
In the meantime I'm going take Eric's advice and get the other tube & be done with it, so I'll just have a spare. I was always going to get another tube & valve assembly anyway, so I'd have one valve and tube modified for lower power and more shots, and another for hunting.I tried the Hatsan USA site with no luck so far. Lets see if they'll ever respond to my emails.
Thanks a few hundred zillion for all your help guys.

Not sure why it refers to the "AT44PA"- it fits all the AT44's- there is no different unit for a PA vs. a non-PA model...

AFAIK, Hatsan USA is not selling ANY replacement parts, only doing warranty service.... insurance excuse....

"sniper" Dan on the CAF may have a gauge.... I'd try him before going to the UK....

Spoke to sniper on CAF a few days ago and he doesn't have anymore in stock. But he'll be getting soon, so when he does I'm gonna order 5 of them from him. So I'll have two working tubes & two spares each. But I wonder exactly where on the valve is the weakest point that causes this leaking issue?
