Ournewesthighpressurefittingspermitdirect
connectionof 360micronOD fused silica,
PEEK,stainless,or electroformednickel tubing
without theuseof liners. The ferrule snaps
into thenut so that thefitting is“one-piece”,
but the ferrule remains free to rotateas the
nut is tightened so that the tubedoesn’t twist.
Becauseof thecompact sizeandfine2-56
threads,a leak-freeconnection that sealsat
pressures inexcessof 20,000psi canbeeasily
formedwith theavailablemanual tool.
VICINanovolume®fittingsgenerallyhavebore sizesof 100-150µm (.004" - .006"),
with someas small as50µm (.002"). Theminimal transfer volumecontributedby
Nanovolume®componentsmakes themespeciallybeneficial inapplicationswith
flow rates in theµl/min range,when the transfer volumecanbecritical.

1/32"fittings,with100µmor 150µm
bore,are ideal forhigh resolutioncapillary
chromatography. Ratedat 5,000psiwith
fingertightnuts, theywill remain leak-tightwell
beyond theburst strengthofmostPEEK tubing.
Thesefittingsaremachined fromhighquality
inertpolymers to the sameexacting tolerances
asourpopularValcozerodeadvolumefittings,
and the taper angleanddetail designconform
to the industry standardestablishedby the
Valco line.
