The Dimple™ super drain plugs

Why would I need a magnetic sump plug in my oil?

Every time you run your engine, it becomes more and more contaminated with many thousands of tiny nano particles of harmful ferrous metal. These metal particles are so small that they cannot be seen by the human eye. They are mainly caused by friction and lots of it. For example an engine travelling at merely 2000rpm sends the pistons rubbing up and down the bore 33 times per second. Astounding really!

The human eye can only see a particle 40 microns or larger. The oil filter can only realistically filter out particles larger than 35 microns. The particles we are looking to catch with powerful oil filter magnets are about 35 microns or less in diameter, the smaller the particles the more harmful to the engine or transmission because they travel everywhere under hydraulic pressure, (oil pressure), and act exactly like a fine lapping compound, continuously polishing down all surfaces.

Let’s understand how big these particles are…

A fine grain of salt is 100 microns.
White blood cells are 28 microns.
Red blood cells are 8 microns.
Bacteria cocci are 2 microns.

The Dimple™ Super Sump Drain Plugs

The best time to use magnetic oil drain plugs and oil filter magnets is from new. When a new engine is fired for the first time it quickly starts to wash itself down internally with oil, so all the left over minute particles of ferrous material from machining, from bores, from piston rings and many other tight moving parts all gets washed around the engine and they all go through the sump at some time and remember, the oil goes through the oil pump before even the oil filter, so that is always unprotected. Grab that metal before it can leave the sump and cause premature wear!

The Dimple™ super drain plugs that we supply are the strongest high temperature magnetised drain plugs available, period! These magnets effectively remove those tiny particles of metal in your oil so you can have peace of mind that your engine is protected and will last longer.

Technical Information On Our Magnetic Oil Drain Plugs.

  • The Dimple™ Drain plug magnets keep on attracting metal particles @ 45MGO’s (magnetic strength) to in excess of 180 Degrees C.
  • A regular grade N neodymium looses magnetism at 79 Degrees C and often dumps all the swarf back into the oil! (What use is that in your engine?).
  • Each Dimple™ Drain plug will have the magnet secured using the finest 2 part resins available. They will not drop out and rattle around your engine like other cheaper products!
  • The Dimple™ super drain plug is of all steel construction and delivered with re-usable solid copper gaskets. (Non SS versions).
  • These plugs are recommended by the society of automotive engineers (S.A.E) and are fitted by many high end car and motorcycle manufacturers including such names as Suzuki and Porsche.
  • These are the strongest high temperature grade neodymium magnets in the world!
  • A Dimple™ specified magnet will last a long, long time. The formula for figuring out how long your Dimple® Magnet will last is this: Our magnets degrade 1/2 of 1% every one hundred years!

The Dimple™ Super Sump Drain Plugs

Make no mistake… High quality magnets are extremely expensive. (Hence the cost of a quality loudspeaker) We use the worlds most powerful type neodymium and state so in our adverts.

Anyone using a magnet like this would be proud to say so as they are by far the most expensive part of the drain plug. A magnets grading is its pedigree. Ours are graded 45MGH.

Don’t forget, some magnets struggle to even hold their own weight when stuck to steel. its reasonably safe to assume that anyone not stating the magnets grading is unlikely to be using a very high grade, otherwise why not advertise the products biggest selling point?

Most people don’t realise that all magnets lose their magnetism as they get hot. The temperature they do this at varies from one grade to another, but the important thing to note with automotive use is that you use a grade high enough that it doesn’t lose its magnetism in hot oil, which can be up to 140 Deg C.

Buying a cheap aluminium sump plug is false economy, if you need a new one every other oil change because it is damaged.
