Prokomon Engine Cylinder Leak-Down Tester Kit – Dual Gauge, Extension Rod, Grey 4-Piece Set

Meet the Prokomon Engine Cylinder Leak-Down Tester Kit, a practical tool for evaluating the health of a gasoline engine without disassembly. By pressurizing a cylinder and measuring how much leaks, you can gain actionable clues about engine sealing and performance, guided by realistic testing workflows.

Overview

The kit combines a dual gauge setup that records both the air pressure in the tested cylinder and the leak rate simultaneously. The pressure gauge covers 0-100 psi and 0-7 bar, while the leak gauge reads 0-100 percent, with a typical accuracy around 0.5 percent. This arrangement supports quick, side-by-side comparisons and helps you interpret results in the context of a spark-plug equipped gasoline engine within a 20 mm plug-well specification.

What’s included

In addition to the common core, the package expands to offer flexible, field-ready testing options. The kit includes a double gauge manifold, an 18 inch hose, an AR2000 pressure-regulating valve, an American type air plug, and a sturdy manifold body. It also provides two universal push-on connectors and two threaded adapters, plus a 14 mm extension rod and an extension hose for longer reach.

• Double gauge manifold and 18 inch hose for integrated readings
• AR2000 pressure regulating valve with a lockable knob
• Two universal push-on connectors and two threaded adapters
• M14 aluminum extension rod with extension hose

How it works in practice

Hook the kit up to an air compressor (your setup), attach the push-on connectors to the spark plug wells, and pressurize to observe the readings. The dual gauges provide a live view of the cylinder pressure and the leakage percentage, while the valve knob lets you manage input air. The extension rod and hose give you flexibility to reach engine bays with limited access.

• Simultaneous pressure and leak rate readings for a single cylinder
• Push-on connectors avoid threading into spark plug wells
• Extension rod and hose support versatile layouts in tight spaces

Real-world use cases and caveats

Users may use the results to explore potential issues like worn piston rings, valve wear, cylinder wall cracks, or head gasket concerns. While the tool supports directional testing and trend comparison, outcomes depend on correct setup, engine type, and proper calibration with your compressor.

Overall, the Prokomon tester kit aims to offer a practical, non-invasive way to gain insights into cylinder sealing and leak behavior. It can fit into routine diagnostic routines or as a focused check during maintenance sessions, helping you decide what further investigation may be warranted.
