Flangeless tube end fittings
1/4-28
Flangeless tube end fittings eliminate the flanging tool required with standard
tube end fittings. The nut turns on the tubing as freely as with our flanged fitting,
eliminating the possibility of cracking or unscrewing that can occur when plastic
tubing is subjected to twisting as fittings are connected.
Cheminert flangeless fittings include our patented* collapsible ferrule design.
This innovative design utilizes a one-piece ferrule engineered to collapse as it
is tightened. The collapse takes place in a very narrow area, resulting in a very
effective seal with virtually no distortion of the tubing ID and no dead volume.
The assembly is rated at 500 psi liquid when tightened by hand. Since only the
tubing and the ferrule come into contact with the solution, the result is an inert
system. Use CTFE ferrules for soft tubing (PTFE, FEP, etc.), but use PEEK ferrules
for harder tubing (PEEK, ETFE, polyurethane, etc.)
Cheminert tube end fittings work with any 1/16" or 1/8" OD polymeric tubing,
and come in twelve different colors for system color coding.

Flangeless tube end fitting
Cheminert low pressure fittings
are ideally suited for flow injection
analysis, low pressure liquid chrom-
atography, and stream sampling
devices. They may be safely used
at pressures up to 500 psi and
temperatures to 50°C. Two designs
of low pressure tube end fittings are
available.
Flangeless
tube end fittings
utilize our new collapsible ferrule,
which grips the tubing as the fitting
is tightened without significantly
reducing the tube ID.
Standard
tube
end fittings are retained on polymeric
tubing by a flange formed with a
Cheminert flanging tool.
