Dual-Gauge Cylinder Leak Down Tester | Precision Diagnostic Kit

Dual-Gauge Precision Cylinder Leak Down Tester

Diagnose engine health with professional-grade accuracy using our Superior Dual-Gauge Leak Down Tester. Unlike a standard compression test, this tool pinpoints exactly where pressure is escaping—whether it’s through the intake valves, exhaust valves, or piston rings—giving you a definitive look at your engine's internal condition.

Professional Design & Accuracy

• Precision Dual-Gauge System: Features a high-quality adjustable left-hand gauge paired with a precision regulator, and a large, high-contrast right-hand gauge for effortless reading of leakage percentages.
• Superior Regulation: The integrated regulator allows for exact input pressure control, ensuring consistent and repeatable results across all cylinders.
• Versatile Functionality: While designed for internal combustion health checks, this tool is precise enough to be used for setting injection barrel valves when used with the appropriate adapters.

Built for the Shop

• Heavy-Duty Construction: Engineered to withstand daily use in a professional garage or a dedicated home shop.
• Extended Reach: Includes a durable 14mm threaded hose designed to fit most modern and classic cylinder heads.
• Complete Diagnostic Solution: Ideal for identifying head gasket failures, cracked heads, and worn rings before they lead to catastrophic engine failure. A standard compression test only tells you how much pressure a cylinder can build. A leak down test tells you how much pressure it can hold-and more importantly, where it is losing it. This is the essential tool for any performance builder or technician who needs a "no guess-work" evaluation of an engine's seal.

-Tech Tip: For the most accurate results, always perform a leak down test on a warm engine. This ensures that the piston rings and valves are expanded to their natural operating tolerances.
