XXDouble compression ferruledesign
XXAvailablewith10-32 threads for 1/16”OD tubing and
M4 threads for 1/32”OD tubing
TheallStainless-SteelVHPFittings includeaunique ferrulesystemwith
twocompressionpoints toprovide twice thegripofastandard ferrule.
Thisdesignalsoallows thebiteon the tubing tobe less concentrated
anddoesnotrestrictthe innerdiameter,asdiscussed intheApplication
Note. The ferrules for 1/16”OD tubingand10-32conedportsare two
pieces, while thegrooved ferrule for 1/32”OD tubingandM4 coned
ports is aone-piecedesign for easier handling, but it will act as two
pieceswithdoublecompressionon the tubingas it is tighteneddown.
APPLICATIONNOTE
Inorder to seal up to the statedpressure rating, theVHP-200-01 ferrule
requires20 in-lbs (2.25N·m) of torque. Similar ferruleson themarket
require tightening torqueof at least 30 in-lbs (3.3N·m),whichcan result in
a restricted tubingpassage, as shown in thepicturebelow. This restriction
can increase turbulenceandadda ‘throttling’ effect to thefluidpathway,
resulting inmixingandotherpotential chromatographicproblems.
