Clutch flange seal?

I have been tinkering with the bike this afternoon, trying to fit the factory racing clutch slave. When taking out the clutch flange (which i swear was welded onto the clutch slave cylinder, btw), I noticed the seal around the actuator rod was looking a bit bad, then saw that a thin strin of rubber had been left on the flange housing in my hand.
So the seal is buggered. It is part 25 on the following diagram.
Does anyone know of a supplier?
Thanks,
Dale

The dimensions are listed on the parts list. I got mine from here
http://simplybearings.co.uk/shop/
Type the dimensions in and away you go.
Was less than £4 delivered.
Make sure it's a sprung seal.

Wish I'd known before I spent some £14 for mine from Aprilia. Also my advice is remove the clutch pushrod first, it takes another 30 minutes but safer than scoring the pushrod.

Cheers for the info.
There turned out to be two seals and not just one, so i'm going to replace both.
The first seal, i think, is this:

The second seal i can;t even identify on an aprilia parts diagram. It looks like the same dimensions as the first, but it has a metal backing, or the rubber has erroded away over time (possible, as I can't find any size markings, like I can on the first, and there is definitely no loose pieces of rubber in the slave cylinder.
Hmmm, if they are the same and the rubber has eroded away, could this be the cause of all our brake fluid going black instantly?

I am absolutely convinced that the two seals are the same, but the second one has deteriorated and been eaten away to such an extent that it has exposed the metal core of the seal.
I have just ordered two seals - hopefully should be here by next weekend so I can get the bike back together.
I'll have to report back on the colour of my clutch fluid after replacing both seals....

Which seals did you order? It appears there are two on the image but one is the gear change seal.

I ordered two of the same seals - 11x22x7 r23 with garter spring.

Oh right. They are easy enough to change without removing the clutch actuator rod.
Mine has been perfect since I changed it.

Yeah they were easy to remove, didn't have to touch the actuator rod.
By it, do you mean both of the seals (the same seal x 2) on the actuator rod, wetween the engine casing and the clutch slave flange?

There was only one seal around the clutch actuator rod for me. Mine was leaking engine oil.

Hmm, odd. Mine definitely has two. :S
