Prokomon Engine Cylinder Leak-Down Tester Kit with Extension Rod | Dual-Gauge Leakage and Pressure Check

Overview

Meet the Prokomon Engine Cylinder Leak-Down Tester Kit, a practical, precision-built tool designed for quick, data-driven insights into your engine’s health. By simulating compression with controlled air and measuring how well the cylinder holds it, you can observe subtle variations that point to wear or damage. The experience feels sturdy in the hand: metal surfaces with a clear dual gauge face, and a reliable, tactile feel as you adjust the regulator and connect hoses.

What’s inside the kit

Beyond the core double gauge manifold, the set is designed to adapt to a variety of engines and setups. It includes a robust rubber hose, two metal adapters, and an assortment of connectors, ready for at-home diagnostics or more involved checks.

• Double gauge manifold and an 18 inch hose for visible pressure and leak rate readings
• AR2000 pressure regulating valve and American type air plug
• Two universal push-on connectors and two threaded adapters for flexible fit
• 1 M14 aluminum extension rod and 1 extension hose for reach and alignment
• Additional connectors and adapters to accommodate longer or shorter hose paths

Key features at a glance

• Dual gauge: test pressure 0-100 psi / 0-7 bar and leak rate 0-100% with 0.5 accuracy
• Compatible with most gasoline engines with spark plugs within 20 mm
• Push-on connectors avoid threading into spark plug wells, simplifying setup

How it helps in real-world use

In regular maintenance, the tester can reveal symptoms that may indicate worn piston rings, worn valves, or cracks in cylinder walls, as well as concerns about head gasket integrity. The data you collect helps you plan next steps with confidence, based on what the readings show.

Using the kit

Here is a typical workflow you can adapt to your shop or garage. Prepare your air compressor as needed, connect the kit to the cylinder, and regulate the input with the valve. As you apply air and observe readings, you will see the gauges respond in real time. Record results, compare across cylinders, and build a practical picture of engine condition.

Note: results depend on proper setup and engine state. The extension rod and diverse adapters are designed to improve accessibility across different spark plug wells and cylinder configurations, increasing compatibility while you work.
