It is highly recommended to use a new washer for each oil change, as the copper is designed to 'crush' and deform during the initial installation to create a seal.
The set covers the vast majority of standard automotive sizes, but always verify the specific washer size required by your vehicle manufacturer's manual.
Solid copper offers superior heat resistance and a more uniform crush, which is necessary for high-pressure oil systems.
Yes, many of the smaller diameters in the 110-piece set are suitable for motorcycle and small engine sump plugs.
The washers are solid copper; the 'gold' appearance is the natural finish of the polished copper material.
Ensure the sump plug was tightened to the manufacturer's specified torque setting, or check the sump pan threads for damage.
Use a digital vernier caliper to measure the diameter of the sump plug bolt shank to select the precise washer size.
To ensure proper performance, always match the internal diameter of the washer exactly to the shank diameter of your drain bolt. Before installation, clean the contact surface on both the sump pan and the bolt head to remove any residual grime or old gasket material, as debris can prevent a flat seal and lead to leaks.
Storage is straightforward: keep the container closed in a dry environment. While copper does not rust, it can develop a patina over time if exposed to moisture, which does not affect sealing capability but may make the washers appear discolored. No specific maintenance is required other than keeping the box organized for easy future access.
