air compressor drain plug

Does anyone know the size of the drain fitting that is located on the bottom of the tank of a Kobalt K7060HFV compressor. I want to replace the fitting with a new fitting that is easier to turn, one like on a radiator.
Another question, can i simply turn the center fitting out and replace it with the wing nut type center fitting? Or do I need get a wrench and replace the entire fitting? I can't find any info on the fitting size, I hope it is a 1/4 - 18 NPT threads. Thanks for any input, Happy Thanksgiving

Most all the fittings on the bottom of any compressor can be replaced. I replaced mine with a petcock style from a radiator. I would just remove it and check out the thread size, should be an easy fix. You won't know anything till you take the present plug out anyway.

I am a idustrial pipe fitter and can 100% tell you that all fittings in air tanks are pipe treads.

Ayuh,... The odds are about 99% that the hole in the tank is threaded 1/4" pipe...
You have to replace the Whole fitting...

I replaced mine with a 1/4" "T" fitting, close nippled to the tank, with a ball-valve on 1 side,+ a pull-cable drain off a Big Truck on the other side...
With the other end of the cable at the top of the unit,... No need to bend over anymore,...
If it Really needs drainin',... 1/4 turn of the valve,+ it's free flowin'...

You can go to Lowes or home Depot or any place like that and buy a compressor drain petcock. They are a pretty standard size.

Thanks for all the replys, i was hoping it was a 1/4" fitting, that about all i could find. My tank drain isn't real difficult to get to, but getting the right fitting up front would make the swap easier. Thanks again

It is a good idea but don't get carried away with the length, keep it well back under the tank, because being down near the floor like that they can easily be broken off that's the reason they don't come that way from the factory.



Mikewb, you need to turn that thing 180 deg because the way it is it will be easily bumped if you move the compressor around but if you turn it the other way it would be pointing up out of the way when the tank is tilted back, still fairly easy to break off on a portable compressor however but not nearly as likely.

I was going to replace the drain tomorrow but it looks like I have changed my mind on how to do it. I will now wait until Friday and go to HD and get a few fittings and a ball valve. The less i have to bend over and drain the air compressor the more bends i will have left to work on my ole truck...thanks again

Those auto drains are great for regular work and that price is great.but I dont care to much for them in the paint shop...If they fail it'll cost you dearly ...plus I'm used to draining the tank as part of the procedure ....something everyone should get used too every day.That cable and ballcock is a great idea and with one more improvement its perfect.....A hose and something to catch the water....My compressor dumps about a half gal of water on the floor which is a pain when you turn the drain off ...Thanks for the good ideas...Have a great thanksgiving...

I have a HDA70600AV filter from HD, although I havn't tried to clean it out yet. I have heard it isn't very easy to work with. i didnt do much research before i bought it, my fault. I do not do much painting, mostly priming and using air tools. Any tips on cleaning the filter i have? I am concerned I will get it apart and it will not go back together and then I will be without air. I will take a look at the drain from HF and see if i have room to use it. thanks
