Cylinder Pressure and Leakage Tester Kit with Dual Analog Gauges

Brief Overview

This is a specialized diagnostic tool for engine condition assessment in professional automotive workshops. The kit enables mechanics to inject compressed air into cylinders and measure both inlet pressure and air leakage percentage, reliably identifying worn piston rings, faulty valves, and damaged head gaskets. As a complement to your diagnostic capabilities, consider pairing this with diesel engine compression testing equipment for comprehensive powertrain diagnostics across fuel types.

Key Features

• Dual analog pressure gauges with large white faces and clear numerical scales for easy reading
• Left gauge: Inlet pressure measurement (0–7 bar / 0–100 PSI)
• Right gauge: Air leakage percentage readout (0–100%) with color-coded zones:
  • Green zone = acceptable tightness
  • Yellow zone = moderate leakage
  • Red zone = critical leakage requiring immediate attention
• Three spark plug-style threaded adapters for compatibility with various engine configurations
• High-pressure rubber hose with brass/steel end fittings for secure connections
• Metal manifold assembly with integrated brass fittings and control valve for precise air regulation
• Complete carrying case with thermoformed interior protecting all components and fittings

How It Works for Your Technicians

The tester operates on a straightforward principle: compressed air is injected into individual cylinders while the gauges display real-time pressure and leakage data. The left gauge confirms supply pressure stability, while the right gauge reveals the percentage of air escaping past piston rings, valve seats, and gasket seals. This dual-measurement approach eliminates guesswork and allows technicians to pinpoint specific failure modes—critical for accurate engine diagnostics and customer communication.

Business Advantages for Resellers

• High diagnostic value: Engine condition assessment commands premium diagnostic fees in professional shops
• Repeat revenue: Worn engines generate follow-up engine work, cylinder honing, and valve jobs
• Professional positioning: Offering this diagnostic capability elevates shop credibility and justifies higher labor rates
• Durable investment: Analog gauges and quality brass fittings ensure reliable performance across hundreds of tests
• Compact case design: Portable enough for mobile technicians or multi-bay shops
• Complete kit: Includes all adapters needed for most domestic and import engines—minimal additional investment required

Why This Matters

Engine diagnostics are fundamental to professional workshop operations. Customers often arrive with vague complaints—rough idle, loss of power, excessive smoking. This tester transforms those complaints into measurable data, allowing technicians to justify engine rebuild costs, valve jobs, or ring replacement with concrete evidence. The color-coded gauge eliminates confusion about severity, making customer explanations straightforward.

This is essential equipment for any shop handling engine work beyond basic maintenance. Stock it as part of your premium diagnostic line.
