Genuine DeWalt N361499 — O‑ring / sealing ring designed as a direct replacement for the seal on several DeWalt circular saw assemblies; sold individually to restore the original sealing function and keep dust/debris out of the guard/housing area.

Fits example models such as DCS570, DCS575, DCS576, DWE575 and DWE576 (and appears in parts breakdowns for nearby DCS/DWE 7" circular‑saw variants).

This small, low‑profile rubber O‑ring is the exact sealing component listed in DeWalt parts diagrams for the blade/guard area; replacing a worn or damaged ring restores proper sealing and helps prevent premature wear from dust and grit.

A simple, genuine DeWalt spare that’s commonly referenced in parts for power tools schematics for the DCS570/DCS575 family — sold as one unit and ready to drop into the original groove during routine repair.
