Description
Overview:
This genuine Echo oil seal is a precision lip seal for Echo 2‐stroke chainsaws, including CS2511TES and CS-2510TES. Made from durable black elastomer bonded to a metal reinforcement, it maintains crankcase sealing and keeps lubricants where they belong, preventing leaks at the rotating shaft. Correct sealing supports dependable starting, stable idle and full power output, while helping protect internal bearings from contamination. It is a direct replacement for OEM No. V505000070 and is engineered to fit the factory housing without modification. Suitable for routine maintenance or repair, it restores sealing performance in compact top-handle and rear-handle Echo saws. As a Genuine Echo part, it provides the fit, material quality and reliability required for everyday use.
