New seal for pressurised keg

[RobMorgan1981]

I've just gone to keg my first batch of beer in a very long time, and realised my seal has cracked.
Can I get replacement from wilko's or the range? Or do I have to buy a whole new screw top?

Search for "2 inch barrel o ring" and you'll find them. Some places cheaper than others. The seals from stovetop espresso makers fit but they're thinner and you might have to stack them. While waiting for a new one I glued the split and wrapped it in PTFE tape and it worked.

My ring is very brittle too so worried it may break even more of I fiddle with it too much.
It's been in the FV for 7 days, so I might just leave it another day, as I hadn't started the transfer yet. I'll try wilko's tomorrow.
In work, I know we have some 3-4mm rubber for making gaskets, so might pop in and pinch some of that,if I can't find any

Wilko's and The Range were no good, so I popped to work and pinched a bit of Gasket, and made my own not a bad match for thickness. Fingers crossed, it does the job
