This 23 mm mini pressure gauge is an one on one replacement for the FX Dreamline factory pressure gauges.
Made of solid steel, chrome plated with a 250 bar wide dial scale.
The gauge comes with several orings what can replace the factory X-ring in case if the alignment is not perfect for the eye. Due to this o-ring there is enough movement to line up the gauge perfectly in eye position.
This is an universal pressure gauge what can be used on several airguns. Never exceed the factory advised fill pressure of your rifle!
