Precision compression for multiple piston ring types: The compression chamber dimensions are meticulously engineered to precisely reduce piston ring diameter, accommodating rings from various engine models. This ensures a tight fit during installation, guaranteeing installation accuracy.

Simple operation, effortless and efficient: Featuring a manual design, pressure is applied via the handle to effortlessly compress the piston ring. Leverage principle ensures effortless and stable compression. Requires no complex skills, allowing even novice technicians to master it quickly and boost engine repair efficiency.

Robust and durable with high deformation resistance: Constructed from high-strength steel with rust-proof surface treatment. Critical components like the compression chamber and handle are sturdy and resilient. Withstands prolonged use in engine repair scenarios and the forces of piston ring compression without deformation or damage, ensuring long tool life.

Safety-focused design with integrated safety valve: Features a built-in safety valve to regulate compression pressure, preventing over-compression damage to piston rings. This ensures operational safety and provides peace of mind during piston ring installation.
