Brass diff plugs, fair price for a good product

Depending on the design of the plug, you have to careful how much you tighten it. If it's just a flat flange the o-ring will deform if you over tighten it, and a harder o-ring material is required. The brass plugs I use have a groove machined in to them so a softer o-ring material can be used (allowing a better seal) but won't "extrude" the o-ring when you crank down on it.

Damn...what an elegantly simple but effective way to stop (some) oil leaks. To rip-off a phrase from those Guiness ads, "Brilliant!" Tom, you might have a future in the LR engineering department, that is, if Land Rover *had* a future. At least it would save' em the expense of all that monkey-snot-from-hell sealer they are using now to stop leaks.

Yeah I see that now that you mention it. How in the hell does that happen? I guess I need to keep a good eye on mine.
<WILD_GUESS>Just a theory, but it might be some combination of the amount of copper in the alloy and the type of oil it's exposed to. I know you're not supposed to use copper pipe with diesel systems because it causes embrittlement and the lines will crack.</WILD_GUESS>
Then again, it could be something as simple as over tightening.

Not sure it is the oil, rather the environment....
Copper will "work harden" with vibration, causing it to fracture. That's why copper isn't used in hydraulic systems, like brakes. Now copper alloys, that's something else.

those plugs are pointless. The plastic ones hold up fine. They we're originally made for te DI's in the engine bay area and it just so happens they fit in the diff. Don't buy them. But its only my opinion.

Zero leak 3/4" BSPP thread steel hex head plug with viton oil ring -- $2.06 at McMaster-Carr. Item number 4835K46. They have brass too, for the radiator plugs.
If you want to spend $20 a plug, just order from me, I'll get them from McMaster and keep the extra. Then you can sleep well at night.

I bought a bucket full of them at the Sod a coupla years ago, 50 p apiece! The ones I have have an aluminum washer for sealing.

Well dammit, yes it is. I could have sworn I got to those searching for BSPP. Soory for the misdirection. They do have BSPP dies.

Actually that's more than likely the case, you are never suposed to expose bronze to gear oil because it makes it brittle and prone to failure, it wouldn't be too shocking if brass behaved simularly when exposed to gear oil. Diff plugs should be steel and they should have a magnet connected to them, but plastic is fine for the filler, if the hex-head rounds off just stick a heated flat-head screw-driver in it, wait a minute and unscrew it.
It depends on the gear oil composition you're using. A lot of heavy trucks have brass components in the diffs. So do Land Rover gearboxes.
Are the fill plugs and the drain plugs the same size? If they are the same size, is it not possible just to go buy some drain plugs at the dealer or somewhere?
Or, is the D2's fill plug the same size as D1/RRC/D90? If so couldn't you just pull the fill plugs off a parts truck and use them...
