The WIKA 213.53 Pressure Gauge is designed for harsh environments, featuring a stainless steel case and an O-ring seal that allows for field liquid filling. This gauge is vibration- and shock-resistant, making it suitable for applications with pulsating or vibration conditions. It is intended for use with gaseous or liquid media that will not obstruct the pressure system. The gauge has a 2.5" dial, a pressure range of 0-100 PSI, and a 1/4" NPT lower mount connection.
