G1/4 Rear Connection Glycerine Pressure Gauge -1 to 9 bar 63mm WIKA

Glycerine-filled compound gauge for panel mounting, -1 to 9 bar (≈-15 to 130 psi) with 0.5 bar scale divisions. Accuracy class 1.6 means ±1.6% of the span, so the max. error is ±0.16 bar across the dial. The glycerine fill dampens the pointer, so the dial stays readable under vibration and pressure pulsation. Copper-alloy measuring element and brass connection. For aggressive media, choose a gauge with stainless steel wetted parts. The G 1/4 thread at the rear centre has a centring spigot for a profile sealing ring. 63 mm stainless steel case, IP65, dual scale in bar and psi. Galvanised steel mounting bracket included. -20 to 60 °C.
