The Class 1 Liquid Filled Fire Service Gauges are designed to provide accurate and reliable pressure monitoring for fire apparatus, pumps, and water systems. Built to meet the demanding requirements of the fire service industry, these gauges feature a highly visible white face for quick pressure readings and a liquid-filled design that helps reduce vibration and needle flutter during operation.

Constructed with a rugged Zytel nylon case, these gauges offer excellent resistance to corrosion, impact, and harsh environmental conditions. An isolating diaphragm provides sub-zero freeze protection, allowing dependable performance in temperatures ranging from -40°F to 150°F. Available in multiple pressure ranges and sizes, Class 1 gauges meet or exceed ANSI and NFPA standards for fire service applications.
