Super Plug's Patented Design
The value of magnetic oil pan drain plugs and differential plugs has been recognized for decades. Since the 1930's, military vehicles have used magnetic oil pan plugs as regular issue. Airplanes, buses, commercial trucks, tractors, fleet vehicles, etc., all use magnetic plugs. Auto racing team uses magnetics to remove particles from their expensive engines. Locomotives to rocket engines that power space craft employ sophisticated magnetic metal gathering devices. The magnets used have been low in flux power (ability to attract) and, for the most part, small in physical size. Until recently, very few magnetic plugs, however, have found their way in to the retail car and light truck industry, unlike the wide application of magnetic plugs found where engines are more expensive or are required to last for a long time.

The Super Plug magnet is physically much larger than most magnets used currently or in the past for gathering metal particles. In addition to the increased physical size and raw energy increase of magnetic material, the ability of the magnet is further increased as a result of the design of the plug and the materials the plug is constructed of. The Super Plug is a two piece design that thread or are bonded together. One of the pieces is easily magnetized, the other non-magnetic. The bolt section that threads in to the typical oil pan is made from stainless steel, a hard material with very low magnetic appeal or ability to magnetized. Stainless steel further guarantees that threading into the oil pan will both be secure and minimize cross threading from occurring, a common problem. The second section of the assembly attaches to the bolt and holds the magnet. It is made of 4140 carbon steel, an easily magnetized material. The magnet is held in place by both magnetic attraction and adhesive. The magnetic energy from the magnet magnetizes the carbon steel but not the stain less steel, thus concentrating all of the energy output at the end of the plug and into the oil flow.

The design of all other magnetic plugs manufactured to date calls for the entire assembly to be manufactured from a low cost metal. These metals are easily magnetized. As a result, the entire plug becomes magnetized as well as the immediate oil pan area surrounding the plug. This causes the relative small amount of energy of the magnet to become diluted, reducing the strength of its attraction. Particles, in some instances, can be attracted to the pan itself, unable to be removed, and in other instances, to the plug's threads.

Super Plug, on the other hand, concentrates all of it magnetic energy at the end of the plug that is projected into the oil. Both the magnetized high carbon steel section and the magnet itself provide a large surface area to attract ferrous particles with no dilution of energy.

The length of the Super Plug also plays a vital role in its performance. Super Plug is much longer than current or prior magnetic drain plugs and extends into the flow of oil where most ferrous particles are suspended. Neither current or prior magnetic drain pan plugs provide such a large magnetized surface exposure in the circulating oil stream.
