25 caliber Uragan 2 Tannk wont take air

[Lakotahicks1]

Hello everyone I am fairly new to this forum and also to PCP air rifles. So here is my problem I have a 25 caliber Uragan 2 and I wanted to
install some shrink tubing over my carbon bottle so I degassed the bottle I then removed the bottle put the sleeve on my bottle
and then I closed the degassing screw I then reinstalled my bottle hooked it up to my Rovair compressor and now the tank wont take any air
I tried cocking the lever while filling but nothing I also don't know anyone with a scuba tank to try and fill it that way I also have a FX impact M3
so I tried to fill it with my compressor to see if it was the compressor but it filled it right up so I'm pretty sure my compressor is ok. Any help you guys could
give me will be very much appreciated I am just sick about this I absolutely love this gun and want to shoot it but cant get it to take air Please help me figure this out
Thanks.

U can try holding the air in the rifle w your finger while the lever is locked. One finger at the end of the barrel and 1 at the slug or pellet entrance. It worked for me twice but now I have a deeper problem I believe. It may work. The pressure would stop building against your finger as the rifle is filling and it may take the air w out escaping anymore. Give it a try. Hope it works for u. Later.
