M12/M14 Threaded Engine Air Valve Holder for Leakage Testing

Main Usage 1: Cylinder Pressure for Valve Seal Replacement

Pressurize the cylinder to hold valves closed with compressed air, making it possible to replace the oil seal of the valve without dismantling the engine. This feature saves both time and labor, ensuring a quick and efficient overhaul process.

Main Usage 2: Leak Detection During Compression Stroke

When the cylinder is in the compression stroke, the tool helps diagnose damaged parts by listening to air leakage sounds. By pinpointing the leak position, you can accurately identify and repair issues, enhancing overall engine performance and durability.

Compatibility

This tool is designed for gasoline engines with M14 or M12 spark plugs. Ensure that the joint of the tool is installed on the position of the spark plug for optimal performance.

Working Requirements

Operate the tool with compressed air, where the working pressure must be between 30psi and 1000psi. The air inlet is a 1/4" quick coupler male plug, ensuring easy and quick connection.

Anti-High-Pressure Features

The upgraded version of this tool uses improved materials (2024 aluminum alloy) and steel wire braided hoses, providing a maximum compressive strength of 1000PSI. This ensures durability and safety during high-pressure applications.
