Filter Indicator Gauge

The HYV-1 Filter Indicator Gauge is a compact, service-proven visual indicator designed to make hydraulic filter maintenance fast, simple, and reliable. Mounted on a spin-on filter head, this gauge provides an at-a-glance reading of filter condition so you can schedule service before restricted flow affects system performance.

Featuring a 1/8″ NPT center-back mount connection, the HYV-1 installs quickly on Hyvair spin-on filter heads and is compatible with many other manufacturers’ heads, making it an easy retrofit for existing systems. Its clear, color-coded scale uses a green zone from 0–25 psi and a red zone from 26–60 psi to instantly show whether a filter element is operating normally or approaching the change-out point. This straightforward visual feedback helps prevent unplanned downtime, protects pumps and valves from contamination-related wear, and supports longer component life.

Ideal for low-pressure hydraulic return and lube circuits, the HYV-1 Filter Indicator Gauge offers economical yet dependable monitoring without the complexity of electrical sensors or wiring. Use it as a cost-effective upgrade over running filters to failure—simply check the gauge during routine walk-arounds and service or replace the spin-on element when the pointer moves into the red.
