AUTO METER Mechanical Oil Pressure Gauge Ultra-Lite 2.3125in — Silver Dial with Orange Pointer, Compact

The AUTO METER 4321 Ultra-Lite is a lightweight, race-proven 2.3125-inch mechanical oil pressure gauge that delivers clear readings with a high-contrast orange pointer and silver dial.

This compact mechanical oil pressure gauge is designed for motorsport and street applications where reliable, easy-to-read pressure monitoring matters. Built around Auto Meter’s proven mechanical movement, the Ultra-Lite uses traditional incandescent perimeter lighting and a simple plumbing-style installation that does not rely on the vehicle’s electrical system for measurement. The kit ships with the fittings, nylon tubing, adapter, bulbs and hardware needed to get it mounted and working quickly.

How does the Ultra-Lite show oil pressure clearly under race conditions?

The 2.3125-inch face combines a silver dial and a vivid orange pointer to maximize contrast and visibility at a glance. Perimeter incandescent lighting keeps the dial readable in low-light environments without altering the gauge movement itself.

• High-contrast orange pointer against a silver dial for fast reads
• Perimeter incandescent lighting for nighttime visibility
• Compact 2.3125-inch diameter fits tight dash locations

What makes the mechanical movement reliable for harsh conditions?

The gauge uses a mechanical movement that resists electrical noise and continues to read accurately when electrical systems are stressed. Mechanical components are straightforward to service, and the design tolerates heat and vibration typical on race cars and performance street machines.

• Proven mechanical movement for consistent readings
• Durable construction for heat and vibration endurance
• Doesn't depend on vehicle electrical systems to operate

What is included and how easy is installation?

Auto Meter provides a complete kit so you get the fittings and bulbs needed to install the gauge without sourcing extra parts. Installation uses a 1/8" nylon line and compression fittings with a 1/4" NPT adapter, making it compatible with common oil pressure ports and race plumbing conventions.

• Includes 1/8" nylon line and 1/8" NPT compression fittings
• Supplied 1/4" NPT adapter for common pressure ports
• Bulb/socket assembly plus red and green covers, mounting hardware, instructions

Why choose this gauge for a build or track car?

The Ultra-Lite balances race-focused readability with low weight and simple mechanical operation, making it a practical choice for builds where cockpit clarity and reliability are priorities. Its compact size fits custom panels and factory dash openings while the included hardware streamlines installation.

• Lightweight design suits performance and weight-conscious builds
• Compact diameter fits custom and OEM dash locations
• Complete kit minimizes additional parts purchases

Who is this for: The AUTO METER 4321 Ultra-Lite is aimed at racers, performance enthusiasts, and custom builders who need a compact, durable oil pressure gauge with quick visual readability. It’s suited for track cars, hot rods, and street machines where a straightforward, mechanical instrument and included installation hardware save time and improve reliability without reliance on vehicle electronics.
