Description
Overview:
The O-Ring (FKM) is a genuine Milwaukee spare for SDS Max corded drills in the Kango range, designed to restore and maintain sealing performance in demanding conditions. Made from FKM (fluoroelastomer), it offers excellent resistance to heat, oils, and common jobsite chemicals, making it suitable for heavy-duty use. This circular seal helps prevent loss of grease and air in the hammer mechanism and gear housing, supporting consistent impact energy and efficient operation. It is engineered for a precise fit on the Milwaukee (Kango) K545S and K500S models and is a direct replacement for OEM No. 4931398297. A reliable choice for routine maintenance or repairs, it helps extend service life and reduce downtime on site.
Key Features:
- Genuine Milwaukee part for assured compatibility and reliability
- FKM (fluoroelastomer) material resists heat, oils, fuels, and common site chemicals
- Maintains seal integrity to minimise grease seepage and air leaks
- Supports consistent hammer performance and impact energy

Suitable for drills used in concrete and masonry work such as chiselling, demolition, channel cutting, and anchor hole drilling on site or in workshops.
