Description
Overview:
This Set of Gaskets for Stihl KM55 and KM55C is a genuine Stihl OEM sealing kit for the 4140 engine platform used across many handheld tools. The gaskets are precision cut from fuel- and heat-resistant composite materials to give reliable, long-lasting sealing between engine components. Correct sealing helps to maintain compression, prevent fuel and oil leaks, and support stable idling and consistent performance in small 2-stroke powerheads. Suitable for garden and light construction machinery that use these engines, the set is ideal for routine servicing or repair work where old gaskets have become brittle, torn, or are causing air leaks. It offers a straightforward way to restore proper engine function on models such as KM 55 and KM 55 C.
