FlushNut Fittings are designed for those
tight-space applications where nut heads often interfere with each
other. When coupled with an appropriate ferrule and tightened
into a receiving port, the FlushNut’s slotted head seats at or near
fush with the top of the port. This feature allows FlushNut Fittings
to reside in closer proximity than any other option on the market.
All FlushNut Fittings are manufactured from 316 stainless steel,
except the P-321 Plug, which is made of PEEK
™
polymer.
Tighten or remove FlushNut Fittings with our specially designed
FlushNut Wrenches, available in 10-32 or 1/4-28 versions. For more
information on the FlushNut wrenches, see page 33.

Fittings are easy-to-use alternatives for
Lee Company 062 MINSTAC fttings systems. These fttings consist
of a TinyTight Ferrule which works with the 6-40 threaded nut on
this page, M-644-03. Choose from two ferrule options, with 0.020”
(0.50 mm) or 0.030” (0.75 mm) thru-holes. To use, simply slide a ftting
head-frst onto your tubing, followed by the ring and ferrule, and thread
this assembly into the solenoid valve receiving port, whilemaking sure
the tubing is bottomed out. No collets, colleting tools or chamfering
tools required; however, if needed for easier assembly of the TinyTight
fttings, the M-150 tool is available. To use, frst place the tool in a
vise, then tighten tubing, ftting and ferrule into the tool as you would
into any port. Once removed, the swaged ferrule will be held in place
on the tubing.
The TinyTight fttings have a pressure range that depends upon the
tubing used for the connection. Please contact your distributor or
IDEX Health & Science for more information.
