Subject: NVC -- Need easy-out or similar tool for 10-32 stainless steel
Content-Type: text/plain; charset=UTF-8; format=flowed
I am hoping for the wisdom of the list is locating an easy-out or
similar tool for SS 10-32 bolts. If any of you have worked with high
performance liquid chromatography (HPLC) equipment (particularly that
made by Waters Associates), you are probably familiar with so-called
ferrule nuts. These are hex-head 10-32 SS bolts with a hole down the
center to clear 1/16-inch OD SS tubing. Basically the 1/16-inch tubing
is connected to pumps, columns, etc., with the ferrule nut followed by a
ferrule. You screw the ferrule nut -- ferule combination into a
specially machine fitting and tighten it down to make a tight seal.
This passed summer, I bought a collection of 1980s-vintage HPLC
equipment to teach my Son lab instrument repair and computer
interfacing. In the process of letting him learn by doing, he snapped
the heads off a couple of the ferrule nuts leaving the end and the
ferrule stuck in the equipment. Parts involved are NLA so there is need
for a way of extracting the remaining part of the ferrule nut and
ferrule. I can get the parts to a Dremel drill press to drill the
tubing out of the broken nut, but then need something to extract the
remainder of the ferrule nut. Are there miniature easy-outs or similar
