Hermetically Sealed

Marsh Instruments Liquid-Filled Gauges are designed to perform in rugged applications and harsh environmental conditions - especially where pulsation and vibration are a problem.  Liquid-filled gauges offer a significant cushioning and dampening effect, reducing pointer flutter and internal gauge damage; also lubricating the internals, and reducing corrosion.
All stainless steel liquid-filled gauges feature a vent top fill plug for pressure relief and ease of venting after installation.  The hermetically sealed construction reduces the chance of leaks, and makes field filling an easy option.
