JJCOCO 150PSI Oil Pressure Gauge Kit 2-1/16" (52mm) with 1/8" NPT Sensor, LED Readout & Programmable Alarm

If you want clear, instant oil pressure feedback for a car, truck, or other 12V/24V vehicle, this JJCOCO kit gives both numeric accuracy and a sweeping visual indicator in a compact 2-1/16" (52mm) housing. The kit is built to be installed quickly with the included wiring harness, bracket, and clear diagram. It supports routine monitoring, towing or performance diagnostics, and safeguards by alerting you when pressure falls below your chosen threshold.

How easy is the JJCOCO gauge to install and connect?

Installation is designed to be straightforward for DIY mechanics and professional installers alike. The kit includes the sensor pre-threaded for 1/8" NPT ports, a labeled wiring harness, and a mounting bracket so you can secure the 52mm gauge in a dash or panel cutout.

• Complete kit: sensor, harness, bracket, and diagram included.
• Works on 12V and 24V systems; ignition-switched power and ground required.
• No splicing or special adapters needed for most vehicles.
• Mounts flush in a standard 2-1/16" opening or with the supplied bracket.

What readings and alerts does the display provide?

The gauge combines a bright numeric LED readout with a sweeping needle for trend visibility, so you see exact PSI numbers and changing pressure at a glance. A programmable low-pressure alarm flashes, beeps, and pulses red when oil pressure drops beneath your set limit to warn you before conditions worsen.

• Digital 0–150 PSI numeric readout plus sweeping needle.
• Programmable low-oil-pressure alarm with audible and visual alerts.
• Peak pressure recall button for quick diagnostic checks.
• Bright LED for clear visibility day or night.

How does the sensor perform and what vehicles are compatible?

The included 1/8" NPT electronic sensor is precision-engineered to resist leaks and handle gasoline, diesel, and high-performance engine conditions. It fits most vehicles that accept a 1/8" NPT pressure sender and works without adapters in the majority of aftermarket and factory applications.

• 1/8" NPT threaded sensor for secure, leak-resistant fitment.
• Compatible with gasoline and diesel engines; suitable for performance builds.
• Corrosion-resistant construction for long-term reliability.
• Peak recall helps identify weak pumps, clogged filters, or relief valve issues.

How can this gauge help during towing or high-load driving?

When towing or carrying heavy loads, oil pressure can change rapidly. The combination of instant numeric feedback, needle trend, and peak recall lets you monitor how pressure responds under load and catch early signs of stress.

• Monitors pressure spikes and drops during towing or heavy acceleration.
• Peak recall captures maximum pressure for post-drive review.
• Low-pressure alarm warns of dangerously low lubrication before damage.
• LED readability ensures information is visible while focused on driving.

Who is this for? The JJCOCO 150PSI oil pressure gauge kit is aimed at drivers who want reliable, visible oil pressure data—garage DIYers, performance enthusiasts, tow vehicle owners, and fleet managers. If you need a compact 52mm gauge with a clear LED readout, a dependable 1/8" NPT sensor, an audible/visual alarm, and a plug-and-play installation, this kit provides the monitoring and diagnostic features to keep track of engine oil pressure without complicated wiring or adapters.
