Viair 90088 Black Face 2″ Gauge
The Viair 90088 is a two-inch dial gauge rated up to 160 PSI. It features a single-needle display and night-readability via illumination. Best for vehicle tire setups, air compressors, and portable systems that require a compact, backlit readout. Best for users who need clear visibility in low-light conditions and straightforward panel mounting. Limitation: depends on a powered setup for illumination, which may require routing a 12V connection.
SENCTRL 0-160 Psi Back Mount Gauge
Equipped with a 304 stainless steel case, this SENCTRL gauge offers IP67 waterproofing and corrosion resistance. The 2″ dial size provides a clear readout for pneumatic regulators, air compressors, and RV regulators. Best for environments where moisture is present or condensation is a concern. Choose this if you need strong weather resistance and a robust back-mount design. Limitation: 0-160 PSI range may be restrictive for higher-pressure systems.
SENCTRL 0-200 Psi Back Mount Gauge
This 2″ SENCTRL gauge expands to 200 PSI, featuring a 304 stainless steel case and IP67 waterproofing. It excels for water filters, pneumatic regulators, and air compressors where slightly higher pressure readings are needed. Best for users who require both durability and a broader range. Caution: higher range can reduce fine granularity near upper limits if not calibrated properly.
Gerchway Tire Pressure Gauge 100 PSI
Gerchway’s gauge features a 100 PSI range with a 12″ hose and a 45° angle chuck for easy access to tight valve stems, including motorcycles. The glow-in-the-dark dial aids readability in low light. Best for automotive and motorcycle tires where access can be challenging. Limitation: 100 PSI may be limiting for larger tires or high-pressure systems.
SENCTRL 0-200 Psi Lower Mount Gauge
This lower-mount SENCTRL gauge offers a 0-200 PSI range with a 2″ dial and 304 stainless steel housing. It is designed for applications like water systems, HVAC piping, and pneumatic setups. The IP67 waterproofing helps prevent condensation. Best for installations where the gauge must be mounted lower than the user’s line of sight. Caution: lower mounting can require longer tubing and careful routing to avoid vibration.
Buying Guide: How To Choose A 2-Inch Air Pressure Gauge
- Choose a gauge that covers your expected maximum. 0-160 PSI works for general tires and small compressors; 0-200 PSI is better for higher-demand applications.
- Back-mount offers simple installation on panels; lower-mount suits installations where the gauge sits below the line of sight. Consider space and access.
- Stainless steel cases and IP67 waterproofing improve durability in damp or outdoor environments. Brass wetted parts resist corrosion in non-coastal settings.
- A 2″ dial is standard; ensure a legible scale and, if needed, glow-in-the-dark features for night use.
- Check NPT size (commonly 1/4″) and required fittings for your regulator, compressor, or tire valve adapters.
- Illumination, long hoses, and angled chucks can improve usability in tight spaces or low-light conditions.

FAQ
- What is a 2″ air pressure gauge best used for? It suits automotive tires, RV regulators, air compressors, and various pneumatic systems that benefit from a compact, readable display.
- Do all gauges require power for illumination? No; only illuminated models require a power source, typically a 12V supply or panel wiring.
- Why choose IP67 waterproof gauges? They resist dust and water exposure, reducing fogging and corrosion in outdoor or damp environments.
- What mounting method should I pick? Back mount is straightforward on panels, while lower mount helps setups where the dial must be read from a lower position.
- Is a higher psi range always better? Not necessarily. Choose a range that matches your typical readings to ensure accuracy and resolution close to your target pressures.
- Can I use these gauges with water or oil systems? Some models specify compatibility with non-corrosive liquids; verify the wetted parts and intended media before use.
