About the Piston Connecting Rod black outline icon
A cylindrical piston crown sits on top with two ring grooves and a round wrist pin at its center, joined to a slim connecting rod that widens into a circular big-end bearing and a notched base. It reads immediately as internal combustion hardware. Use it on auto repair shop sites, spare parts catalogs, engine diagnostics apps, motorsport branding, and mechanic service menus.
The design is vertically symmetrical, with the narrow rod waist contrasting against the wide crown and bearing to create a clear silhouette. It works alongside gear, wrench and car engine icons in the same collection. At small sizes the ring grooves can close up, so 32 px and above is the safest floor.
This is the black outline version of the piston connecting rod 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.
