Thepatenteddesignof our fused
silicafittingsensures stable, leak-
freeconnectionsat temperaturesup
to400°C, andundistorted ferrules
thatareeasily removedand reused.
Columnsmaybechangedwithout the
riskof the leakswhichcandevastate
systems suchasmass spectrometers
or atomicemissiondetectors. This is
accomplishedwitha spring-loaded
Replacement ferrules for fusedsilicaunionsandself-compensating
nuts (Agilent injectornuts)
These reusable ferrules seal at the tip,andaredifferent from standard ferrules.

Fusedsilicaunions
The fused silicaunion*hasaquartz liner,providingan inert connectionzoneof
minimal volume. Since the seal occursonlyat the ferrule tip, the total sealing
force isminimized, leaving the ferruleundistortedand reusable.
Note:
The ferrulesused in thisunionareunique,due to the seal at the tip.
Standard ferruleswill notwork in thisunion.
