Bottom blanking plug

Hi all, i'm after a bit of info here please. I've discovered a small leak coming from the bottom blanking plug on my FAC MK2 rapid.I've taken the plug and washer out and the washer had what looked like an ancient o ring moulded into the inside of it. It just crumbled as soon as i touched it so obviously it needs replacing. So, was this an o ring thats become attached to the washer over time or was it actually moulded to it during manufacture? Also do i need to get the whole plug/washer assembly or just the washer?
 TIA

If you can contact Dr Bob..
He makes a nifty replacement bottom plug screw..
It uses a captured O-ring to seal!!

BTW the standard one uses a 1/4" Dowty Washer- Bonded Washer.....
