Designed to hold to higher pressures than standard fangeless fttings
Eliminates loosening of nuts caused by tubing twist
The design of the Super Flangeless ftting system includes a two-piece
ferrule with a lock ring which operates as a bearing against the nut.
The nut can then spin freely without turning the ferrule while rotating,
preventing the tubing from twisting during the tightening process.
This feature helps eliminate subsequent loosening of the nut, making
the Super Flangeless system ideal for applications subject to vibration.
These products are also well suited for connections that need to be
broken frequently, since the lock ring holds the ferrule in place on the
tubing until intentionally removed. Use the LT-300 Removal Tool –
found on page 33 – to release Super Flangeless Ferrules from tubing
for repositioning.
The fttings systems on this page connect 1/16”OD tubing into any fat-
bottom 6-40, 6-32 or 10-32 fat-bottom port. Use the FEP NanoTight
™
Sleeves from page 19 with these fttings to connect capillary tubing
with OD sizes between 70 µm and 1 mm. Choose from a variety of nut
styles for the 10-32 nuts, depending on the application. The headless
6-40 and 6-32 nuts can be tightened using the N-290 extender tool
found on page 33.
