Hatsan Gladius tuning regulator

For the Hatsan Gladius airrifle (also called Hammerli Pneuma) we have a pressure regulator available that can be pushed into the pressure tube.
This regulator is vented to the atmosphere without any modification to your pressure tube. So no drilling in the tube and also no creeping up in power during time.

The benefits of the Hatsan Gladius tuning regulator


  • Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
  • A constant pellet speed over the full working pressure range.
  • Maxiumum use of the air volume due to our ultra compact build.
  • It will give you a better shotcount and a full flat shotstring immediately.
  • Adding a regulator to your airrifle will probably give you the biggest benefit in the tuning process.
  • Often the rifle will make less noise due to better balance in air usage 


When you order one of our regulators you will receive:

  • Your regulator preset on to your own wishes;
  • A pressure scale in Bar’s on the regulator, for fine-tuning or re-adjustment;
  • We will include a “Huma regulated” breech sticker;
  • Fitting instructions as pdf download

Pressure settings of the Hatsan Gladius Tuning Regulator

Your Hatsan Gladius regulator comes preset on the most common pressure setting. It is equipped with a clear pressure scale label, so you can very easy re-adjust, or fine tune the pressure setting without the need of a regulator pressure tester.
The output pressure range is adjustable from 90-170 bar. If you have other wishes please contact us.

Aditional information:

Only when you have bought your rifle in- or after 2017,  please let us know the production date of the pressure tube. This date is printed on the fillcap in month/year.
For older rifles it is not necessary.

Easy to install and great instructions. It gives a nice steady pressure and the result is that I get a much nicer shooting with my Hatsan Gladius.

Gun: .25 cal Hatsan Gladius Long W. Lothar Walther Barrel

Contrary to Georges I really like the clever design that allows you to mount it without having to drill a hole in the air tube, I have however made some other modifications to the valve housing and do not plan to use it without the regulator but instead of drilling a hole in the tube I milled a little groove in the valve-housing to vent the regulator, I also turned of a bit of material and coned the visible part of the valve housing so now it looks like the air-tube and mechanism-housing belongs together and it shure made the install more elegant. ;-)

I have only just installed it in a new gun so I assume the barrel (though made by Lothar Walther) needs a few hundred shots through it to preform really good, early chrono testing is really consistent. We'll see about longevity but for now I'd definitely say it was money well spent.

I installed the Huma regulator in my Hatsan Gladius .177 cal. My 10 shot group size went from quarter size to dime size at 43 yards. I'm using JSB 10.34gr pellets and getting great velocity. The regulator was super easy to install, and gave no problems at all. I found the instructions to be straight forward and very easy to follow. This is a great "drop in" fix that I'm going to enjoy for a long, long time.

Thank You Huma.

I have purchased the model for Hatsan air tube. Now the regulator is mounted in and I have done some velocity measures. It seems to work as it should. The only issue is the venting method. I find both modes described in the manual not very practical or too invasive. In my other regulated PCP airrifle there is a tiny hole in the cylinder drilled in the right place by the factory. Such method is more « elegant » in my eyes. I will continue my tests in order to learn whether doing nothing about venting is really decreasing the performance. Generally, I am very satisfied with the regulator. There is a clear gain in the accuracy of my Gladius.

Reply of Huma-air:

Dear Georges,

Because it is a after market product the venthole is not standard in the Hatsan. If you preffer to make one it will be a ellegant solution and it will work great on your Hatsan Gladius
