Re: [APD] eBay Needle valve (S series) take 2

["Terry Barber" <terbarb at alltel_net>]

Swagelok has a "proprietary" type fitting that uses a ferrule and tube
(swage uses two ferrules) assembly usually.  Only swagelok valves....blah
blah will fit with swagelok parts. Companies do this stuff to force you into
using their brand.      The fittings you need will be "swagelok" to "hose
barb".   The size of the fitting is in the specs for the valve.  The page I
showed you shows fittings that are "swagelok" compatible - these will also
work too.  This means they are the correct size to fit the "swagelok"
fitting that is on the valves.      Do you want me to tell you a part
number?    I can do that for you............what diameter tubing  will you
be using?

http://www.swagelok.com/fittings/tube_fittings/tube_fittings_101.htm    This
is a tube fitting 101 page and has lots of information to those new to this
type of fitting - more commonly seen in industry than home use.
