Description

For the Weihraugh HW100 airrifle 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. This model is suitable for all HW1xx models with a front fill or quick fill unit on the front side of the cylinder.

The factory reg can be bridged by removing the steel ball from it. When removed the factory regulator will not function anymore and the Huma-Air regulator will take over the pressure adjustment.

Fitting is very easy, just depresurize the rifle and unscrew the cylinder endcap off the side of the action. Then remove the large o-ring of the endcap and push the Huma-Air regulator inside the pressure tube facing the pressure label to point towards to the barrel end. Then screw the endcap back in the cylinder and you are ready.
