Drain Plug
Have a 2005 6.0L diesel. Was wanting to make a new drain plug out of stainless. The thread is an odd thread. Does anyone know what the thread on the plug is?

Thanks for the info Mike. So I should make it out of Brass? Do you happen to know what the thread pitch is. I measured it and it tells me it is an odd thread. 14-1/2 x 2.5 mm. I looked up on the charts and it goes from 14mm to 16mm

I think he was specifically making reference to the O ring as well. If you choose to MAKE a brass fitting, you should also be prepared to make it where it can be equipped with a neoprene O ring. I don't think a brass fitting would be good sealing with friction only as it would require tightening. With the O ring, you could finger tighten it (better for brass).
The brass replacements don't really cost all that much, do they? I don't know as I haven't bought one, yet.

I want to say I paid about $13 at Tousley, but the part # isn't working at the Tousley site. For $15-$16 why bother making one?
EDIT: I was typing when you responded...I can understand wanting to make your own....go for it!

Brass, so you dont wreck the plate, yes o ring so you only finger tighten. The o ring is the seal. Thanks Tim. I agree, make one yourself, if you can, but its only 15 bucks. Its the o ring thats key. I dont know the thread exactly, it is a weird one, so course. Double check what you make by meshing it up to the original and see how tight she matches up.....

Buna-n would be my first choice. It is available and not that much money.
It will also stand up to diesel fuel.

Here is a chart.
Rubber Compounds of O-Rings - Viton, Neoprene, EPDM, Nitrile
It could be used but not on the should be used list.
Buna-n or Viton® are the better pick for many reasons.

HFCM Water Separator Drain Plug
Wanted to put my .02 in on this thread. I just replaced the drain plug on my 07 6.0L and noticed the base of the stock plug had been eaten away including part of the threads. My intuition tells me that it is also meant to be a "sacrificial anode" to let the water react with the sulphur prior to getting into the engine. If that is the case I am concerned about the "upgrade plugs" from Riffraff as they look like brass and I wonder if they would work the same. You guys are more up on this stuff than I so I was wondering if anyone else thought of this or noticed a similar condition of the plug.

meant to be a sacrificial anode. It would not be a steel plug and there would be
a replacement interval in the service manuals. There is not. It's just a steel plug.

So they use brass as a sacrificial anode? Interesting...
