Maglite Care and Maitenance




This instructable will show some simple ways to keep your maglites alive and functioning properly for longer. I typicaly do this type of maitenance once a year. Sorry about the date on the pictures couldnt find an option to turn it off and forgot to update it.


Step 1: Gather Some Supplies

First you need these three things
-Paper towels or rags
- Jack's Formula 327 Multilube or other multipurpose silicone lubricant (NOT Petroleum based lubricant because it may damage the rubber "O-Rings")

Step 2: Disasemble

Remove the top of the flashlight incliding the lens and focusing cone also remove the battery cap. Smaller flashlights without the button on/off switch will be on untill you remove the battery cap.

Step 3: Locate "O"-Rings

Now find the "O"-Rings and wipe them clean of any old dirt and grease. Make shure to get the threads inside the flashlight also.

Step 4: Re-Lubricate the Threads and "O"-Rings

Now take some lubricant and spread it on the threads and "O"-Rings.

Step 5: Close It Up

Close it all up and clean away the extra lube.

Step 6: All Done

Now you have finished a simple tune up of your maglites possibly adding years of life or atleast making them smother and easier to use. When you are closing all of the peices together they should go in smoth and if not add some extra lube then try again. Now all of your maglites should focus smothly and be better water sealed.

    FYI, there's supposed to be an "n" in the word maintenance. Also, as mentioned below, petroleum jelly is fine to use and some manufacturers recommend it.

    Maglite O-rings are fine with petroleum jelly; it's actually specified on the in pack instruction sheet - a small amount every 6 months on each threaded section and O-ring.

    good ible only complaint is no mention of using a silicone lube as anything petroleum based will eat your o rings

    no worries, not a fan of maglites but i still cant see a nice o ring destroyed by someone who uses petroleum based lube as opposed to silicone... and you got my vote dude
