Liquid Filled Gauges offer a significant cushioning and dampening effect, reducing pointer flutter and internal gauge damage; also lubricating the Internal, and reducing corrosion. All stainless steel Liquid Filled Gauges feature a ventable top fill plug for pressure relief and ease of venting after installation. The high pressure ranges offer a Helical Bourdon Tube for longer gauge life and increased durability. The hermetically sealed construction reduces the chance of leaks, and makes field filling an easy option. Typical applications include refineries, chemical plants, offshore platforms, oil rigs, marine applications and OEM processes. NOTE: Items are available on special order. However, minimums and lead times apply. Consult factory.
