0-15 Tire Pressure Gauge

The MOROSO 0-15 tire pressure gauge (SKU MOR89550) is a precision analog instrument designed for engine builders, performance mechanics, and automotive enthusiasts who demand accuracy in low-pressure applications. Whether you're tuning a drag racing setup, calibrating a forced-induction system's boost reference, or managing tire pressures on specialty vehicles, this gauge delivers reliable readings where precision matters. Analog gauges eliminate electronic dependencies and battery concerns, making them ideal for shop work, competition environments, and vehicles experiencing high electrical demand.

Built by MOROSO with a 2-5/8 inch dial face and a white background for clear visibility under shop lighting and engine bay conditions, this gauge measures pressure in 1/2 pound increments across its 0–15 psi range. The analog needle design responds instantly to pressure changes without lag, critical when monitoring vacuum leaks, boost control lines, or low-pressure fuel systems on fuel-injected engines. The compact form factor and 0.96-pound weight make it portable for field diagnostics, while the sealed needle mechanism resists vibration-induced drift common in high-performance engine bays.

This gauge excels in applications where standard 0–60 or 0–100 psi gauges lack resolution: low-pressure turbo reference lines, vacuum-assist systems, fuel pressure regulators on carbureted engines, and emissions control diagnostics. Mechanics performing baseline tuning, boost mapping, or troubleshooting fuel delivery issues will find the 1/2 psi increment granularity invaluable for identifying pressure loss or regulator drift. Keep one in your diagnostic kit for quick verification without breaking out oversized gauges.
