Huben Does Huben GK1 hold pressure well?
- Thread starter invisibleflash
- Start date
One of the dealers had one that was in storage after 1 year, and it was still at the same 300 bar when he put it in storage. So, yes, if it is working properly.

i made a post about the gk1 leak i had when it was pretty new.
managed to get it pretty tight again, but after over a year, it slowly leaks again.
have not checked from where yet.
EDIT:
i have checked where the new leak is now. it was the fill-port. opening up the fill check valve, showed some aluminium oxidation under the o-ring. i cleaned it. i added silicon crease to the check valve and the o-ring and for now the leak is sealed again. a simple task, but still annoying.

sorry, i would have, if i could find it again. seems like it was not a thread, but most likely actually somewhere in 'your' master thread. can't find it in my listed comments from my profile.
the gun leaked from the power adjuster part. on the new (from luchtbuks) gun this part looked a bit mangled from a wrench even. they send me a new part under guarantee, but ti turned out, with some silicone grease and tightening, the leak could be fixed, so i still have the old part in the gun.

@grouch-o Is it post #139 in this thread?

I shot 4 mags back to back to test it out today, and it started double tapping. I noticed the trigger became lighter and even though I was shooting slow it dumped air and jammed. Going to give Kelly a call in the morning. When I first got my GK1 It jammed and dumped air multiple times. I was...

my GK1 also has a slow leak (about 100Bar over night), but i am not sure how to check from where it is leaking. i have tried some silicone spray on the check valve screw and around the power adjuster, but i can't see any bubbles so far. i wonder what are the other places and ways to check them...

Not mine. I have problems with it since I bought it. It was brand new, out of the box...with a leak. Sent it back for a repair. Under warranty, free of charge. Was good for a while, but leaks again. Small leak, but still. 300bar to 260 in weeks.
And before you think I used it a lot. No. 1+ year passed. I shot maybe 5 magazines. A dust collector.
Then, I bought an AEA Megalodon. I have it almost a year now. Same sh*t! Leaks from the get go. And I shot only one magazine! Changed a couple of things in it. Still leaks. Way faster than the GK1.
Basically these two, totally killed my enthusiasm for any PCP airguns. Not happy.

first release ones have a very slightly undersized valve that can slow leak from high pressure. mine does sometimes. temp changes exacerbates it. it will stop leaking at around 250 bar.
they can also get a leak from the check valve. mine has done that too...but that's a 5 minute job to replace, and kit comes with a spare!
