Manganese Steel Strong, Spring-Loaded Fit, Engine Assembly Made EasierProduct AttributesColors: Silver and BlackSizes: Piston Ring Compressor Tool: 3.43*2.97*2.68 inchPiston Ring Plier: 6.69*3.94 inchFour Corner Wrench: 3.05*3.05*0.23 inchWeight: 13.30 ozMaterial: Manganese SteelPackaging: 1* Piston Ring Compressor Tool, 1* Piston Ring Plier, 1* Four Corner WrenchPackage Size: 12.20*7.87*2.81 inchProduct Feature & Functions1. The tool's working diameter spans from 2.36 inches to 5.90 inches. An internal spring design supports fine-tuning the circumference, making it suitable for various piston sizes within that range2. The main components are manufactured from manganese steel, a material known for its durability and resistance to deformation. It maintains its integrity through repeated clamping and release cycles3. To use, adjust the band to the required diameter and position it over the piston rings. Insert the four-corner wrench and turn to compress. The ratchet teeth lock in place, avoid the band from backing off during installation

• Included Components and Thickness Capacity: The piston ring compressor tool package contains 1pc piston ring compressor tool, one set of ring pliers, and a four-sided wrench with a 0.23-inch drive head. The sleeve works with piston rings ranging from 1.3 mm to 7 mm in thickness for standard engine work
• Variable Diameter with Spring Tension: The ring compressor band features an adjustable span from 2.36 inches to 5.90 inches. An internal spring assists in fine-tuning the circumference. This allows the same tool to be used on pistons of different diameters within that range
• Guided Compression for Engine Assembly: Using a piston ring compressor during reassembly helps the rings enter the cylinder without catching on the deck edge. The tool holds the rings compressed while the piston is tapped into place. This method helps avoid damage to ring edges and cylinder walls
• Manganese Steel Durability: The piston ring compressor tool body is made from manganese steel, a material selected for its toughness. It resists deformation even when significant pressure is applied to tighten the band around the piston rings during the compression step
• Simple Working with Locking Ratchet: To use the piston ring compressor tool, adjust the band to the piston's size and slide it over the rings. Turn the four-corner wrench to reduce the band's diameter. The ratchet teeth engage to avoid the band from loosening while the piston is installed
