The ultimate
fingertight fitting... |
Fingertight fittings slide
onto stainless steel or PEEK 1/16” capillary tubing and allow
convenient connections to HPLC columns without the use of wrenches.
Importantly, fingertight fittings form extremely stable connections
which are stable to over 5000 psi.
Besides their convenience, fingertight fittings are important
because they allow an HPLC system to be compatible with ALL manufacturer’s
HPLC columns. As shown in the diagram below (center), different
column end-fittings require different lengths of tubing to protrude
beyond the ferrule (as designated by distance “A”) in order to
form a proper fit inside the end-fitting. Stainless-steel 1/16”
fittings are ”fixed-ferrule,” e.g. not adjustable once swaged
for a certain type of end-fitting. Fingertight fittings form a
stable, but non-permanent swage on 1/16” tubing so any type of
column can be used on the HPLC system without changing the fittings.
So changing from columns with Valco-style end-fittings to Waters
end-fittings to Parker end-fittings is a snap.
Fingertight fittings are tightened and loosened by hand, so there’s
no need for those little wrenches that one can never seem to keep
track of. Our WIDE-BODY fingertights allow the user to generate
lots of torque for tight, leak-free connections with minimal effort.
Once you’ve tried our fingertight fittings, you’ll wonder how
you ever lived without them.
MetaChem offers two types of PEEK fingertight fittings, pictured
below, as well as super-strong stainless steel MetaTite™
fingertights. Our PEEK fingertights are designed for use with
both stainless steel and PEEK 1/16” capillary HPLC tubing.
Our one-piece PEEK fingertights (P/N 4050, below,
right) are most popular since there isn’t a separate ferrule to
keep track of. Our two-piece design (P/N 4060,
below, left), however, can be somewhat more economical since the
ferrule wears out more quickly than the fingertight body and replacing
the ferrule is less expensive than replacing the entire fingertight.
