I don't seem to be able to fill my Hatsan at44. I am 99.0% sure it is my fault because it's brand new and it is doing the same thing that my only other PvP did, I sent that one back. I have a Hatsan pump and all the seals are right but when I pump it the air busses out at the probe where it enters the tank. What am I doing wrong?

Photos or a video would help... Quick Disconnect not properly connected... Hand pumping, I'd guess the purge valve on your pump isn't closed...

You said all the seals are right, but most commonly, the o-rings on the probe get nicked if you are not careful how you insert the probe. A new AT44 comes with spare probe o-rings, might inspect the ones on the probe and see if there are any nicks/chips out of them and replace if necessary. The edges of the fill port hole are a bit sharp on the AT44, gotta be slow and easy when re-filling that rifle.

Yep, most likely it's the fill probe o-rings that are damaged. Replace and add some silicone grease.

Is the AT44's air tank empty? If it is you have to cock the gun to keep the hammer from holding the tank firing valve open. If this is what is happening the air you hear escaping is coming out the barrel instead of the fill probe. Once you have partially filled the tank, the pressure will keep the valve closed.

I am at a loss as to what I'm good wrong.I did everything the way you all have said and it still leaks .I have had this problem with 2 other guns and have never been at to fill one.

Check your fill hose connections on your pump. Maybe they're loose or need some teflon tape wrapped on threads.

I'm going to go with what Rodeo said, hammer holding valve open, OP said it was two new guns, new guns are shipped empty (or supposed to be)...
I'm interested in reading a follow up on this...

If the air leaks at the probe interface it might be you have the wrong probe, or it's just not seated properly, or some combination of bad Orings/marred seating surface, or the hose is leaking. Use some soapy water to find the exact area, just hearing the air escape will not pin down the area.

I would advise against adding "Silicone Grease" that would only cause more issues. The silicone would attract dust and cause different problems.

I keep my fill probes inside a hard case to avoid this. I also use canned air giving them a quick blast prior to putting them away. I don't want my o-rings drying up when I need them.

Thank you for all the support I am going to try my other Hatsan fill probe,brand new unused, and see what happens. If that doesn't work then I will send it back. I just can't help wondering why I keep having the same exact issue with 4 different guns. On a good note poly carbonate plastic is a great cheap backstop for traps and backyard shooting. 65 shots from my at44 and no holes or crafts just dents and divots. Plastic is only 1/4 inch thick!!!

Can you take & post a good macro (close-up) picture of the probe & its o-rings? It might help us to help you. I've had 4 Hatsans & never had that issue. Never been a fan of fill probes. I'm a quick connect kinda guy.

If I didn't use any lube would it work? Do I need to pump real slow? Why does it look like the o rings are to small to even create a seal? Also the air is coming out of the hole the probe goes in so it's obviously not going in the tank and coming back out,seal problem. Any other suggestions are welcome.Thanks.

You never mentioned if you're experiencing the leak while the probe is inserted, it should be ALL the way in (no o-rings showing) or AFTER you pull the probe out. The o-rings on the probe should be just a hair bigger in diameter (by a few thousandths mm)than the probe diameter. If they are not protruding a hair over probe diameter than rings are incorrect size.
Sorry if that sounds stupid but I'm trying to get a really clear idea of the problem you're having. If you have replacement probe o-rings try some new ones. VERY LIGHTLY grease with silicone before inserting.

So I was not able to get silicon grease today so I'm going to send it back before I run over the time limit. Thanks for everything I will contact you guys when I get it.
