Fibre washers and soldering?

[Ben-gee]

Ummmmm ummmm, it hurts can I stop now?
Fibre washers are indeed tough hard little beggars. Often, particularly with high pressure they will weep slightly when fitted but rather than graunch them up (may tear) if you leave them for a while the fibre swells up and no more leak for ever and aver amen.
