o-rings list on the Yellow

I got a slow leak at the filler too. So, I ordered this list myself. Replaced all of them. No leaks since.

Well my MKII finally crapped out on me, it's finally time to take this puppy apart and replace with some good nitrile orings.  I know that someone has posted all the sizes it takes I just can't remember where it was.  It's leaking from the most common leak too, at the probe fill.

Mine broken from the get go so I replaced with the one in the package. Works for now but would also like to get some good rings (tough and resistant to tear and durable yet soft enough to seal well).

I finally got my "version 2" regulator today!  I've been so busy, that I haven't even had a chance to run any strings on it yet   I can tell you I put it in, set it at the same pressure, and the velocity is exactly the same(which is what I expected).  It is definitely smaller in every way.  They re-designed every part of it.  It definitely takes up less space.  I made some measurements before I installed it, so I should be able to give some concrete volume numbers tomorrow regarding how much space it takes up in the cylinder.  Of course, a shot string will be done too

Thanks for being the pioneer. Does this regulator replace the original one that came with the pistol?

Brian I bookmarked that thread   Menards here in town carries a good brand of nitrile orings that you can actually buy individually from what my brother was telling me.  Menards is one of his favorite places to go, maybe I should take a good tour of the place even though I hate going to stores

This is handy and great to know they worked well for you. I am ordering the same.

I got a chance to run a full string with the V2 Huma installed tonight.  I didn't try to adjust to get the exact same velocity, and there can be a slight variation in exactness of regulator marked settings.  That being said, we're only talking single digit differences in tune average here, and wanted to note that.  Everything else was left exactly the same, and I made no adjustments to the gun, other than the regulator swap(both set at 130bar).

Huma V1 - 28 shots at 897fps with 7.25 grain Terminators
Huma V2 - 31 shots at 893fps with 7.25 grain Terminators

Long story short, the V2 Huma did get me 3 more shots, and allowed me to break the 30 shot mark at my chosen level of tune.  The entire regulator is smaller.  I measured both regulators so I could calculate the difference in space they take up in the tube.  I did not count the small space inside the cap of the cylinder that the V2 Huma goes into, since that space is down stream of the V1 reg as well.  The numbers come down to this:
Huma V1 takes up  11.99 cc
Huma V2 takes up  5.86 cc
That is pretty impressive to me that Huma put in the effort and managed to cut the space taken up by the reg in half.  They did it quickly, and free of charge to those of us who ordered the V1.  Huma deserves big props for this one I think!

I wish I had thought to get an exact measurement of the air cylinder when I had it apart to calculate the real volume of it, but I'm not taking it apart again(unless something breaks).  I've heard everything 65-68cc on the cylinder, and I thought it was 67cc.  Obviously, the efficiency would be better with heavier pellets, but with the 7.25 grain it is around 1.13.  With the 10.5 grain it would be closer to 1.3.  I imagine it would be 1.4-1.5 with the 13.4 or 15 grain pellets.  Either way, that isn't exactly horrible for a 10" barreled air gun  

I forgot to note that the big o-ring was taken off when installing the reg! I just didn't take it off when I took the picture.

Thanks, but I wouldn't call myself a pioneer.  There were others that started tinkering with these neat little pistols before me  

To answer your question, it does the job the one that came with the pistol was meant to do, but it isn't removed from the gun.  The factory one is "bypassed", but left in place.  I technically did remove mine, but it required some modifications.  I don't think removal is really necessary, unless you are trying to extract every little bit out of the pistol, and the difference is still minimal I'd think.

Donny thanks, as usual you did a great write on the comparison of the Huma V1 and V2 regulator.

So this list of O-rings is specifically for the PP700?  It wasn't in the title.  Silly question but, what does "Duro" refer to?  Thickness?  Density?  I see 70 duro in this post, and people are saying get 90 duro...  What does it mean?

[Sfttailrdr46]

Not 100% sure but I think that is wear/abrasion resistance rating , I'm sure one of our other members can step in and confirm this

[SilentMatt]

Durometer- hardness of the o-ring.

Ah, I forgot about that...   

Thank you!!

finally got the huma, day and night between fiddling with the factory, I settled around 795 to 805 almost 40 shots, very little hammer spring . 105 bar David

David, sounds like big improvement, what caliper is the PP700 ?
I received my Huma a week ago and have not had time to install and test it.

Excellent!!  I can't wait to see everyone's results with this Gen2 Huma! 

I did receive my pistol on time (Thursday), in case anyone was wondering...  I must say, pictures don't do it justice!  I'm really liking this pistol so far!

Did you shoot it? How did it go?
