Product: Piston Ring Disassembly & Assembly Pliers Why you need this tool Simplifies piston ring removal and installation, reducing risk of ring breakage or piston groove damage. Provides controlled, even expansion of the ring for safer, faster installation during engine maintenance or field repairs. Durable construction and heat-treated components ensure a reliable tool you can use repeatedly. Key features and benefits Purpose-built: Designed specifically for disassembly and assembly of piston rings for car repair and small engine work. Compatibility reminder: Confirm the pliers’ size carefully before purchase to avoid incompatibility with your piston rings and pistons. Heat-treated for durability: Precision heat treatment increases strength and service life while allowing the piston ring to be opened slightly so its inner diameter becomes just larger than the piston outer diameter, making ring installation easier and more secure. High-quality materials: Made from chrome vanadium steel with silicone resin components. The combination is durable, oil-resistant, aging-resistant, and corrosion-resistant for long-term use. Easy to use: Place the piston ring on the pliers at the ring’s gap, grip the handles and slowly compress to open the ring evenly. The controlled motion reduces the chance of ring deformation and makes installation straightforward. Portable and economical: Lightweight and reliable, suitable for use in a shop or on the go. Replace piston rings anytime, anywhere. Function and performance Precise opening action prevents overstretching or twisting of rings. Stable jaw size and fine workmanship maintain consistent results across multiple uses. Corrosion-resistant finish helps maintain accuracy and longevity even in oily environments. Compatibility and sizing Intended for use in car repair and compatible small-engine applications. Also noted for use as a manual pump on board to refuel the outboard. Suitable for outboards for Yum. Always verify the pliers’ dimensions and ring size compatibility before purchase to ensure proper fit. Typical use scenarios 1) Routine engine maintenance: Quickly remove and install piston rings when rebuilding or inspecting automotive pistons in a garage or shop. 2) Field repairs and roadside service: Compact, durable pliers for emergency ring replacement when working away from a full repair facility. 3) Marine/outboard work onboard: Use during small outboard engine maintenance; noted for use as a manual pump on board to refuel the outboard and suitable for outboards for Yum. How to use (brief) Fit the ring into the pliers at the opening. Firmly grasp the handles. Slowly compress to open the ring evenly, position it over the piston, then release carefully to seat it into the groove. Materials and care Chrome vanadium steel body with silicone resin parts. Clean and lightly oil after use to prevent corrosion. Store in a dry place. Note Confirm size compatibility before purchase to avoid fit issues.
