Identifcation of washers for Drainage sink

[wwade]

I'm not a plumber and need to save a bit of money. Wondering if someone could help me identify the parts I need and where I can get them online.

After deciding to clear the undersink cupboard it appears we have a slight leak coming from drainer part of the sink, the water slightly leaks from the end cap on the pipe.

What I need is, I presume a new internal washer to go inside the pipe which has a lip on the end, picture (a) and a rubber blank for the end cap, picture (b)

The dimension of the pipe internally coming from the sink is 31mm

Your help would be greatly appreciated.

They look like Franke basket strainers. Spares are available from Central Services

Thank you for the link. Will send them an email, hoping they can sell me the individual parts. Many Thanks.
