Designed for placing inside the pressure tube. There are two o-rings on the regulator body who seals inside the tube wall. The regulator is vented to the atmosphere for excellent regulating behavior and no creeping up in power on the long term. The regulator has a seperate volume bus (plenum) matching the caliber and chosen pressure range.
The regbody is only 16 mm long with a very small neck. This ultra compact build makes sure there is almost no lose of air volume in the pressure tube.
