Flangeless Fittings

Flangeless Fittings eliminate the need to fange
tubing. This removable and reusable systemprovides several benefts:
Convenience:
Flangeless Fittings are easy to use. Just slip the nut
and ferrule over the tubing and fnger tighten the assembly into your
receiving port. In tests, it is shown that the ideal amount of torque to
achieve expected part performance should be approximately 3 – 4
in-lbs (0.34 – 0.45 N·m). Check out the line of special tightening tools
designed to adapt tomany standard torque wrenches, on page 33 and
the new adjustable torque driver, VHP-4000 on page 8.
Minimal Down-Time:
Component replacement is quick, taking only
a few seconds — unlike the signifcant time required to fange tubing.
Cost-Effectiveness:
Repairingafangedtubingassembly requires a costly
fanging tool or the purchase of a complete replacement assembly,
including a new length of tubing and a set of fttings. The Flangeless
Fittings system typically requires only one new ferrule at minimal cost
when repairing a connection.
The 1/4-28 andM6 Flangeless Fittings for 1/16”, 1/8” andmetric sized
