Bosch 2" Electrical Water/Oil Temperature Gauge SP0F000049 — Black Dial, 100–280°F Range, 12V Backlight

The Bosch SP0F000049 is a precision 2" electrical gauge that monitors water or oil temperature from 100–280°F with a black dial, removable bezel panel, and included sending unit and adapters.

This compact Style Line gauge blends Bosch engineering with a clean, readable display for automotive and marine dash installations. Designed for a standard 2-1/16" panel opening, the unit arrives ready to mount with wiring required for connection. It includes a 1/8" NPT sending unit plus adapters, 12 volt internal backlighting, and mounting hardware — ideal when you need a reliable temperature readout that fits small instrument clusters.

How does this gauge display temperature clearly on a small dashboard?

The SP0F000049 uses a high-contrast pointer on a black dial face and a bright internal 12V backlight to ensure legibility day or night. The compact 2" diameter keeps the instrument unobtrusive while remaining easy to scan at a glance.

• Black dial with bright pointer for quick visual reference
• 12 volt internal illumination for nighttime visibility
• Fits a 2-1/16" opening for compact dash integration
• Black bezel and removable mounting panel for a finished look

What does it include and what wiring or fittings are needed?

The gauge ships with a sending unit threaded 1/8" NPT and three temperature sensor adapters to match common fitting sizes. Electrical hookup wire is not provided, so plan to supply appropriate 12V wiring and ground connections for a negative-ground system.

• Included sending unit with 1/8" NPT thread
• Adapters: 1/4", 3/8", and 1/2" for versatile installation
• Mounting hardware and removable bezel panel included
• Requires user-supplied hookup wire; 12V negative-ground only

Will this gauge work for both water and oil temperature monitoring?

Yes — the calibrated range of 100–280°F covers typical operating temperatures for both engine coolant and oil in many automotive, light industrial, and marine applications. Always confirm compatibility with your engine’s recommended sensor type and placement.

• Temperature range: 100–280°F suitable for common coolant and oil ranges
• Electrical measurement via included sending unit for reliable readings
• Compact 2" face suitable for multi-gauge clusters or tight dash spaces
• Designed for general-purpose monitoring; check engine-specific needs
