Piston Ring Compressor Tool, 40-85mm Capacity, 4-Ring Adapter Set

Brief Overview

This piston ring compressor tool is engineered to protect engine rings from breakage during the critical cylinder installation phase. The tool securely compresses piston rings before insertion, then releases cleanly once the cylinder is positioned. Designed for engine rebuild shops and field mechanics, it covers the most common engine sizes (40–85mm) with four graduated adapter rings. The complete set arrives in a molded carrying case for job-site portability. For shops handling larger bore engines or needing specialized ring removal equipment, consider pairing this tool with dedicated piston ring removal pliers to streamline your rebuild workflow.

Key Features

• Adjustable Compression Clamp: Chrome-plated metal clamp with circular collar, flat jaws, and threaded bolt with wing nut for precise, tool-free tightening
• Four Interchangeable Ring Adapters: Black crescent-shaped adapters in graduated sizes accommodate most common piston configurations
• 40–85mm Coverage: Handles the majority of automotive and small-bore industrial engines
• Tool-Free Operation: No hex keys or additional tools required for adjustment or release
• Durable Construction: Steel clamp with blackened finish; adapter rings engineered for repeated compression cycles without deformation
• Portable Carrying Case: Red molded hard plastic case with cavity-fitted interior protects tools and keeps components organized on the bench or in transit
• Quick Release: Adapters separate cleanly from the cylinder once installation is complete—no risk of getting stuck in the bore
