Product Description

The HUSQVARNA 505155801 is a genuine OEM piston ring designed to maintain proper compression and sealing between the piston and cylinder wall in Husqvarna small engines. This ring controls oil consumption, supports consistent combustion, and helps sustain engine performance over extended service cycles.
