💡 What is a drain plug crush washer used for and how does choosing copper or aluminum affect sealing?

This small seal fills microscopic gaps between the drain plug and the oil pan to create a leak-free barrier, and they are replaced at every oil change to prevent drips. - Copper provides a softer, more malleable seal on cast iron and steel surfaces. - Aluminum is ideal for aluminum pans and helps prevent galvanic corrosion when metals touch. - Replacing the washer each oil change helps ensure the seal remains tight and leak-free. - Keep a ready assortment on hand to service multiple vehicles quickly and accurately.✝️
