SG Tool Aid 33500 Cylinder Leak-Down Test Kit

The SG Tool Aid 33500 Cylinder Leak-Down Test Kit is a professional-grade diagnostic tool designed to accurately assess the internal condition of engine cylinders. By measuring the percentage of air leaking past valves, piston rings, and head gaskets, this kit helps technicians pinpoint the source of compression loss without the guesswork of a standard compression test.

Key Features:

• Dual-gauge design measures both supply pressure and cylinder leakage percentage simultaneously
• Color-coded gauges for easy reading and interpretation of results
• Solid brass fittings and quality construction for long-term durability
• Standard 14mm spark plug port adapters included for broad engine compatibility
• Flexible air hose with quick-connect fitting for easy cylinder access
• Tests for leakage past intake valves, exhaust valves, piston rings, and head gaskets
• Packaged in a durable storage case to protect gauges and fittings

The leak-down test method is widely regarded by professional mechanics as a more precise alternative to compression testing. By pressurizing the cylinder with regulated air and listening for escaping air at the intake, exhaust, or crankcase, technicians can immediately identify worn rings, burned valves, or a blown head gasket. The SG Tool Aid 33500 is an essential addition to any professional or serious DIY engine diagnostic toolkit.
