Outline icon of an engine piston with two rings, connecting rod and round wrist pin
About the Piston black outline icon
A piston head with a peaked crown and two ring grooves sits above a short connecting rod that ends in a round wrist pin boss with side bosses. It reads as engine internals, motor power and mechanical repair. Fits auto repair shop websites, spare parts catalogs, vehicle service booking apps, engine diagnostics dashboards and motorsport or tuning branding.
The composition is strictly vertical and top-heavy: the broad crown block anchors the upper half while the narrow rod steps down to the circular pin end, giving a clear silhouette. The two horizontal ring lines are the key identifying detail. Pairs with wrench, gear, oil can and car engine icons; keep it at 24px or above so the ring grooves stay separate.
This is the black outline version of the piston icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
