Tell me more of your setup. Whose reg? What fpe are you atnow?
As to the tube, the Hatsans have the worst tubing I have worked with so far. And they seal at a larger diameter so thinnest wall is where it seals. Compounding that the axial force is higher pushing on the threads.
I do not recall Hatsan or any other pcp with a safety valve.

I've had the BT65 for 2 weeks now and right out of the box the big brute was shooting a 52fpe with .22 21gr at 1040fps!
I say brute because I recently sold my lighter AT44 long in .177 which was a pleasure to handle and I
really miss the lever action cocking. Yea in retrospect I should have bought another AT44 in.22 and hogged out the valve seat and ports but I've always been an impulsive buyer.
Anyway I bought an Altaros regulator which they set to 135bar. I wanted to shoot 21gr pellets at 900fps but the 150bar I set the reg to is shooting them at 925fps. I was ok with that but it only shot 18 rounds before dropping velocity below 150bar when being filled to 200bar. Being an OCD nut I couldn't live with that having 2X10 shot magazines. I guess I took the easy way out and just added a little extra air. I now plan (thanks to the forums reaction) to lower the reg a
little so I can get my 20 shots near 900fps.
The AT44 also had that tiny hole near the air fill end drilled nearly through. I think it's an inexpensive burst valve setup.
