To add to the last post.
Swagelok fittings are great and easy to use. 37 degree flared stuff is about 1/2 the price, but you gain the aggravation of flaring.
I have found the best 37 degree flaring tool for stainless is made by Ridgid and has an offset cone. They can be bought on line new for less than $100, like this one
http://cgi.ebay.com/Ridgid-Flaring-...303QQssPageNameZWDVWQQrdZ1QQcmdZViewItem As for benders, there are 5 good ones, all essentially the same design, Swagelok, Ridgid, Imperial, new Parker, and the old Parker with the forged handle.
I have used 4 of the 5 and like the Swagelok best. It is about 3 or 4 times the price of the next three, and probably not worth it for the normal person.
The next three are almost as good, nothing to complain about, the Ridgid is my choice of the next three.
The old forged Parker is very nice and my choice for small lines like 3/16 and 1/4. The parker benders I have are old, I have not seen that style for sale new. The new parker benders for sale appear to be about the same as Ridgid and Imperial.
I think that with careful hand straighting a line made from a coil can look just as good as one made from straight, although harder to do and look good.
