AutoMeter Z Series Mechanical Air Pressure Gauge – 52mm | 0-150 PSI | Air Suspension | 2620

Monitor your air suspension system pressure with precision using the AutoMeter Z Series mechanical air pressure gauge — engineered with AutoMeter’s ultra-precise bourdon tube meter movement for accurate, reliable pressure readings across the full 0–150 PSI range. The 0–150 PSI range is specifically suited for air bag and air suspension system monitoring, covering the full operating pressure range of most air suspension setups. As a mechanical gauge, no electrical connection or wiring is required — the gauge reads directly via the included nylon tubing and 1/8” NPT fitting, making installation straightforward and eliminating the need for a sending unit or power source.

Key Features

• Bourdon Tube Meter Movement – Ultra-Precise Mechanical Sensing: The AutoMeter Z Series uses a bourdon tube meter movement — a curved, sealed tube that straightens proportionally as internal pressure increases, mechanically driving the gauge needle. AutoMeter’s bourdon tube movement is engineered for maximum accuracy and durability, providing precise pressure readings across the full range without the signal noise or calibration drift that can affect electronic pressure sensors. The bourdon tube is also inherently vibration-resistant, making it well-suited to the underhood and chassis environments of air suspension installations
• 0–150 PSI Range – Air Suspension Optimised: The 0–150 PSI range covers the full operating pressure range of most air bag and air suspension systems — from fully deflated (0 PSI) through maximum operating pressure (typically 100–150 PSI depending on the system). The scale is optimised for air suspension monitoring, with clear graduation markings across the full range for easy reading at a glance
• Mechanical Operation – No Wiring Required: As a fully mechanical gauge, the ATM2620 requires no electrical connection, sending unit, or power source — the gauge reads directly from the pressure line via the included nylon tubing. This simplifies installation significantly compared to electronic gauges and eliminates potential electrical failure points. Ideal for custom builds where minimising electrical complexity is a priority
• 52mm Diameter – Standard Gauge Pod Fitment: 52mm is the industry-standard diameter for aftermarket gauge pods and custom dash gauge clusters — the ATM2620 fits any standard 52mm single or multi-gauge pod without modification. Compatible with the full range of AutoMeter and third-party 52mm gauge pods and mounting solutions
• 1/8” NPT Connection – Universal Fitting: 1/8” NPT (National Pipe Thread) is the standard thread size for automotive pressure gauge connections — compatible with the vast majority of air suspension manifolds, air line fittings, and pressure ports. Adapters are widely available if your system uses a different thread size
• Nylon Tubing Included: Installation nylon tubing is included in the kit — no need to source separate tubing for a basic installation. Route the tubing from your air suspension pressure source to the gauge location
• AutoMeter Z Series Aesthetics: The Z Series features AutoMeter’s clean, modern sport gauge face design — black dial with white markings and a clear lens, suited to custom dash builds, gauge pods, and performance interiors where a clean, purposeful gauge aesthetic is desired

Common Applications

• Air bag suspension system pressure monitoring (street, show, and custom builds)
• Air ride suspension — single or dual circuit monitoring
• Custom gauge dash and gauge pod installations
• Any application requiring 0–150 PSI mechanical pressure monitoring

Note: Mechanical gauge — no electrical connection required. Route nylon tubing away from heat sources, sharp edges, and moving components. Secure all tubing connections before pressurising the system. Verify your air suspension system’s maximum operating pressure does not exceed 150 PSI before installing this gauge. For dual-circuit air suspension systems (separate front/rear pressure), two gauges are required for independent monitoring of each circuit.
