📝 Product Overview
Product Details
✓Material: Red Copper, which presents a distinctive red colour, almost pure copper as opposed to impure or alloyed forms. Pure copper content>99.7%. As an excellent sealing material, copper gasket has good ductility, suitable softness, can fill the gap between flange and oil pan.
✓Process: 1) Annealing heat treatment process: Increase the ductility and reduce the hardness of copper. 2) Pickling and chromating: A complete, dense and non-destructive passivation film is formed on the surface of copper. After pickling and passivation, the corrosion resistance of copper gasket can be increased by more than 10 times.
✓Function: Regularly replace the oil drain plug washers to reduce the risk of oil leaks to keep your engine safe. It's important to choose a true quality gasket to get the job done.
✓Fitment: Oil drain plug crush washers dimension: inner diameter is 18 mm / 0.71 inch; outer diameter 22 mm / 0.87 inch; thickness is 1.5 mm/ 0.06 inch. Will fit for M18 oil drain plug. Use amazon fitment strip to ensure this will work with your vehicle. Also check your own plug gasket dimensions is suggested.
✓Value Pack: Professional processed red copper gaskets provide much better sealing performance than plastic, rubber, aluminum alloy seals. 20pcs pack are plenty enough for many oil changes, saving you money and time over your OEM part options.
