    Pressure sealing washers

    On my PSI heads they use O-ring to seal the studs to prevent water from entering the cylinders,They are a pain to install and more of a pain to remove,plus become a one time use only.So in search of a better way of sealing I ran across these.Mcmaster-Carr sells them for about 1.77 each.OUCH! I contacted the company and got some samples sent out(for 5/16" or 8mm threads.I figure others on here might have a use for them too.If anyone would like to try a sample I have a few extras.Also if we find there is a need we could buy 500-100 in bulk.I would think we could get them from the company under .20 each.Here they are:
