Overview

This is the most powerful plug available and was designed specifically for GA aircraft use. This is about the least expensive thing you can add to your aircraft that will extend engine life and prevent damage to your engine. The plug end is very high quality with a special rolled thread to prevent leaks, is cad plated to prevent corrosion and drilled for safety wire. The rolled thread size is 1/2” NPT and this fits all Lycoming, Franklin and many other aircraft engines. The extremely powerful high temperature, Alnico magnet is pressed and locked into the plug permanently and will outlast your engine. This powerful device extends into the oil and removes all ferrous material that is suspended in and circulating with your oil causing wear.

Note: Unit is experimental. Please inspect your sump pump and oil pickup prior to the installation of this plug to ensure that there are no obstructions which would interfere with the unit.

Reviews

Seems like a good product. I installed it in a forward-positioned drain hole so it can be removed and inspected after draining the oil from the rear-mounted Saf-Air valve.

Excellent product. Must have for picking up metal before the filter and smaller particles the filter misses.

Not rounded at the top, but nicely manufactured, the magnetic part seems perfectly embedded on the plug. i think it will be used on my new performance engine.

If there is any ferrous metal suspended in your oil, this plug will hold on to it! The magnet is so powerful my compass is still spinning (Unfortunately it had metal particles stuck to it while in the plastic packaging, not easy to clean this off)

ull disclosure, I purchased this drain plug as I was searching for a heavy duty magnet for a rear end in a car. However, upon receiving the magnet I am a little disappointed in the fit and finish of what I received. The magnetic portion measures 11/16ths long and has a flat cut end, where the photo show a magnet that proportionally to the base, looks almost an inch tall and having a nice polished domed end. The threading on the base is dinged up from being shipped from the manufacturer to the vender in bulk packaging. If you are threading this into and aluminum housing, might want to chase the threads with a die if this is a big concern to you. Finally, as the other review mentioned, there are some minor amounts of metal flakes on the product from manufacturing, and my (1) plug it was shipped in a little zip-lock bag inside of a bubble mailer. Recommend getting tracking shipping as magnets can get stuck to mail processing equipment and lost if packaging rips open.

Weak magnet, not the same product as shown in video. It’s not strong enough to hold itself to a vertical steel surface
