Re: [PSUBS-MAILIST] O ring groves

Hi Jens,
Great detailed photos.
It looks like the brass ring is just clamping down the rubber seal.
It probably makes it easy to replace the rubber seal if it fails.
O rings were invented in the 30s (so I learnt today) & I guess this 
was how they sealed things back then.
