Anyone have an old sump plug off a puma? (Measurements please!)

Ideally the 2.2 variant.
These are replaced with each oil change. It has an integral O ring.
I'm looking to replace with a fumoto oil drain valve, and hoping to get the sump plug thread measurements, and if possible a good pic of the O ring part, and where it mates on the oil pan. The fumoto valve is supplied with a fibre type washer, so need to ensure that it will seal properly.

Ive got a Fumoto on RRS 2.7 (same plug as 2.2)because it is protected by a skid pan
I used a Stahlbus on the 2.2 Puma as the tube allows you to direct the horizontal flow downwards into a tray. The Stahlbus also has a sealing cap as well as a stop valve. Double security and keeps dust out. The Stahlbus is more compact and less likely to get hooked up offroad than the more protruding Fumoto
Neither have leaked where they seal to the the pan but use a different seal to the "winged" o ring on the standard plug

I don't change my plug on services(prepares to to be flamed down) but always have a good look at the seal.
I personally wouldn't fit the valve, my concerns are...
-I do a fair bit of corrugated dirt roads and would think the weight swinging of the drain thread may lead to the sump cracking.
-I'd be concerned a rock or stick may hit it when driving on tracks.
-It could fill with dirt/water/mud and not be usable when needed.
They have thier places such as machines due to tight access but for once or twice a year is it worth it?

I would not fit a Fumoto to a PUMA either. Its too exposed and even with the plastic locking clip accessory could get hooked and broken or the handle could get inadvertently opened:o On the RRS it is protected by the protective skid pan. I can change the oil without removing the skid pan if I want.

The Stahlbus on the other hand is very light and compact and addresses all the concerns Alien mentions on a Puma where the drain is exposed. The cap is sealed and keeps dust and water out.
The beauty is the draining tube directs the oil where you want. The Puma sump drains horizintally and is messy to control

Thanks for the measurements.
The Stahlbus sounds good. Never heard of them before now, but eagerly youtubing to see what they are all about. The enclosed valve cover is a big plus. The fumoto is a little exposed in this department.

I've run one for 7 or so years now on my other vehicle. Never had an issue with it, even when running 3.5kg/mm coilover springs (very hard).
I think the main concern is the dirt and mud getting into the valve actuating workings (it's a ball valve design), I think the risk of sticks and sump cracking would be negligible- a zip tie or some tie wire will prevent the valve from opening when not required (above its already fiddly up and turn method to open), and the weight is not that significant to cause an issue for cracking. If an impact to rip it off were to happen, the sump plug position of the puma would probably mean you'd have bigger issues to attend to.
I guess if you look at it as a long term investment, the 40 or so bucks for a fumoto valve is cheaper than 4 changes of a sump plug, if one were to factor that into a maintenance schedule. I myself would go this way for convenience only. It literally makes an oil change a 5 minute affair with no mess (oil down the armpits etc).

I have a collection of Disco 3 and Falcon six cylinder sump plugs, I don't bother replacing them unless the seal is damaged. I dropped the oil in the Puma at 12000Ks after we got back from Maralinga and just used the old plug again.
