Use the two-hand manual vacuum suction gun, which comes with a vacuum pressure gauge and is equipped with multiple-sized connectors. It is stored in a portable toolbox. Manually create negative pressure and it doesn't require an electric power source. It can be used for extracting brake fluid in cars and for vacuum leak detection of pipelines. The transparent liquid storage cup makes it easy to observe the liquid volume. It is suitable for auto repair and maintenance operations.

The entire set of tools is stored in a hard plastic toolbox, with dedicated card slots inside. All accessories are placed in order, preventing parts from being knocked or lost. It is convenient for use when going out for on-site repairs. The main hand-pushed suction gun has a non-slip red handle, making operation effortless. It generates negative pressure by manual pressing and does not require an external power source. It can perform detection tasks normally even in non-powered repair sites. The accompanying vacuum pressure gauge has a clear dial scale, allowing for intuitive reading of vacuum values. This facilitates real-time observation of the pipeline negative pressure status and helps the operator determine the sealing condition of the pipeline.This manual vacuum suction gun is designed for both pumping and tapping purposes. It is equipped with a vacuum pressure gauge and is a commonly used manual tool in automotive maintenance and repair. It can be used for tasks such as brake fluid replacement, pipeline vacuum testing, liquid extraction, and oil extraction. This tool is suitable for both automotive repair shops and individual vehicle maintenance.

The kit comes with various specifications of adapter connectors, transparent hoses, and a liquid storage cup. These accessories are suitable for different vehicle interfaces. It can be used for vacuum testing of vehicle pipeline sealing, as well as for extracting brake fluid, various liquids, and achieving both liquid extraction and filling functions. During brake fluid replacement operations, negative pressure is used to extract the old brake fluid, ensuring a controllable operation process and reducing the possibility of air mixing into the brake pipeline, thereby improving the quality of the oil replacement. It is also applicable for negative pressure detection of cooling systems and fuel pipelines, and can detect whether there are leakage problems in the pipelines.

The operation method is simple. Select the matching connector to connect the pipeline, and press the handle to establish a vacuum. Observe the data on the pressure gauge. The transparent liquid storage cup allows for a clear view of the extracted liquid volume, facilitating observation of the extraction progress and convenient control of the operation volume. The tool structure is easy to disassemble and assemble. After the operation, the soft hose and liquid storage cup can be removed for cleaning of residual oil, reducing corrosion and extending the tool's service life.

Before use, ensure that the connectors are tightly connected. During operation, press the handle steadily to avoid forceful operation. After the operation, empty the residual liquid in the storage cup, wipe the tool surface of oil stains, dry it, and then store it in the toolbox. This tool is an auxiliary manual tool for automotive repair and is suitable for routine vehicle maintenance and repair. It helps maintenance personnel complete tasks such as brake fluid replacement and pipeline vacuum leak detection. It is a practical and useful tool for automotive maintenance and repair.
