Some ice cream tubs provide nylon like material for making washers; likewise some Chinese take-aways come in nice strong nylon like tight lidded boxes ; very useful for putting bits in as you dismantle things. I have quite a few but still nearly run out when taking some things to bits. The moral - eat more ice cream and Chinese.
Plumbers outlets also useful for various washers for sealing.
Anorak observation...O rings are round and have a round cross section (or sometimes square/oblong)...what is being discussed here are washers which are round, yes, but have a flatter cross section.
The new Nippy tanks come with screw on caps and have an O ring captive by the thread at the top....presumably the O ring just fits nicely around the threaded neck and gets slightly squashed by the inner cap top to further seal.
(thoughts...so how does air get in to allow petrol out
)
