Carolyn and others,

        Having used lines built by others, but never having built one
myself, I need to take advantage of your experience...

        For the Kel-F vessels, are you using stainless steel or teflon
ferulles [sp?] with the swagelok fittings?  Thanks to all for the
information on wall thickness/internal diameter.  Obviously a sturdy wall
is needed.

        In general, what type of ferulle is recommended with metal-to-metal
swagelok connections--teflon or steel?

>Steve,
>Our Kel-F tubes have been drilled to 5/8 internal

>Good luck with your line
