Our Votex drain plugs are proudly MADE IN USA. From the Stainless Steel bar stock material, CNC machine that cuts our plug right down to the hands of the VOTEX crew that craft each individual drain plug. We carefully and pridefully construct our plugs here in our home state of Wisconsin. This ensures that we supply drain plugs manufactured with real quality stainless steel (Not Pot Metal) that will last for countless years to come. We include an aluminum crush washer; Yes also MADE IN USA. <br><br>What makes our drain plug unique outside its flawless craftmanship and top notch materials is the heart of it, a HIGH TEMPERATURE NEODYMIUM MAGNET. Our plug uses a rare earth high strength neodymium magnet, rated specifically to function in high temperature environments extracting unwanted ferrous particles from your vehicles engine. The VOTEX drain plug will operate in temperatures to 150°C or 302°F. A quality motor oil will tolerate oil temperatures up to 250 degrees, but starts breaking down once you reach 275 degrees. The operating temperature for engine oil is between 194 to 230°F, so our magnet will work in temperatures far past that of engine oil. <br><br>Neodymium magnets are one of the strongest magnets available on the planet, and we use one of the strongest grade versions available. Our magnet has the strength to hold weights over 2.2lbs! This empowers our plug with enormous strength to effectively pull these unwanted metals out of your motor oil resulting in longer engine life. Loose metal debris in your engine oil can slowly start to wear on the internals of your engine. <br><br>One must note that the drain plug market has a plethora of options, most of which are constructed of aluminum. Aluminum is an inferior metal choice due to its strength and commonly shear/snap leaving you with a broken plug stuck in your oil pan. Aluminum has no place as the material for a drain plug.
