Wika Model 213.53

The Wika 213.53 is the industry-standard industrial bourdon tube pressure gauge for vibration and pulsation duty. Its stainless steel case protects the movement in harsh environments, and the glycerine case filling dampens needle flutter, lubricates the movement, and prevents internal condensation — which is why a filled 213.53 survives for years bolted to a reciprocating compressor that destroys dry gauges in months.

A distinctive engineering detail: the O-ring seal around the connection makes the gauge field-fillable — the case can be topped up or filled on site for high-vibration applications. The companion model 212.53 is the identical gauge in dry (unfilled) form where damping isn't needed.
