20PCS M12 Red Copper Oil Drain Plug Crush Washers Gasket Seal Ring

Features

• Material: Crafted from high-quality Red Copper, our Oil Drain Plug Crush Washers display a striking red color, indicating their purity as they consist of almost pure copper rather than impure or alloyed forms. With a copper content of over 99.7%, these gaskets serve as excellent sealing materials. They possess desirable ductility and suitable softness, enabling them to effectively fill the gaps between the flange and oil pan.
• Manufacturing Process: Our copper gaskets undergo a meticulous manufacturing process to ensure their quality and performance. Firstly, they undergo an annealing heat treatment process that enhances their ductility and reduces their hardness. Secondly, they undergo pickling and chromating, resulting in the formation of a complete, dense, and non-destructive passivation film on the surface of the gaskets. This treatment significantly improves their corrosion resistance, increasing it by over tenfold.
• Function: Maintain the safety of your engine by regularly replacing your oil drain plug washers. By doing so, you minimize the risk of oil leaks. It is crucial to select a reliable gasket to accomplish this task effectively.
• Compatibility: Our Oil Drain Plug Crush Washers are specifically designed for use with M12 oil drain plugs. The washers have an inner diameter of 12 mm / 0.47 inch, an outer diameter of 20 mm / 0.78 inch, and a thickness of 1.5 mm / 0.06 inch. To ensure compatibility with your vehicle, please use the Amazon fitment strip. We also recommend checking the dimensions of your own plug gasket.
• Value Pack: Our professional-grade red copper gaskets offer superior sealing performance compared to plastic, rubber, or aluminum alloy seals. With a pack of 20 washers, you'll have an ample supply for multiple oil changes, saving both your money and time compared to OEM part options.
