• The Model 659 pressure gauge provides users with a solid-front case design and pressure-relieving back design in all stainless steel construction
• These pressure gauges are available in both 2½" or 4" sizes, in panel mount and low mount configurations
• The liquid fill minimizes the effect of these severe environments, protects the gauge internals, and provides continuous lubrication on the mechanism, all adding up to extended service life
• Liquid filling also provides greater protection of the gauge internals from corrosive atmospheres
