Poly-Flo
Flareless Tube Fittings
REDUCE INSTALLATION TIME AND LABOR
COST
To assemble the Poly-Flo (R)
fitting, just push tubing into fitting and tighten the
nut. There is no need to disassemble - no fumbling for a
loose sleeve. This fitting has a plastic sleeve which
snaps into the nut. The complete unit - body, nut and
sleeve - is furnished assembled, ready for installation.
When used with Poly-Flo", PVC tubing, fitting is
assembled finger tight - no wrenches needed.
TIME SAVING COMPARISONS
Tests show that Poly-Flo 1,
fittings can be assembled in an average time of 11.7
seconds.
These studies made under shop conditions. While actual
time might vary depending on field conditions, the
relationship between time values should remain constant.
NO TOOLS NEEDED FOR TUBING
INSTALLATION
No wrenches, flaring tools,
benders or other tools are used for installation.
Tubing is cut to length with a knife, tubing cutter or
shears. It is flexible, bends readily by hand. Plastic
tube racks and bend holders are available for holding
tubing in position.
EXCELLENT HOLDING POWER NO
TUBING TWIST
The Poly-Flo (R) fitting when
assembled finger tight on Imperial Eastman Poly-Flo (R)
or PVC tubing will hold the burst pressure of the tubing
itself.
The nut revolves around the sleeve as it is tightened,
preventing twisting and weakening of the plastic tubing.
A UNIVERSAL FITTING
Poly-Flo fittings are used with
plastic or soft metal tubing for pneumatic
instrumentation circuits and applications with other
gases and liquids.
Acetyl copolymer sleeves, for use with Poly-Flo,,, PVC
tubing, are furnished with Poly-Flo (R) fitting sizes of
1/4" through 1/2" O.D. Universal brass sleeve
and nut assemblies, for use with Impolene and Nylo-Seal
(R) I, (SN and NF) tubing and soft metal tubing, are also
available for these sizes, and are furnished as standard
with 1/16", 1/8" and 3/16'' sizes.
The versatile brass nut (half-knurl,
half-hex) with plastic sleeve is easily and quickly
finger tightened on Poly-Flo 11, PVC tubing. The hex
portion permits wrench tightening (1 turn after
fingertight). Wrench tightening is recommended for all
applications where brass sleeves are used, and is
desirable whenever service conditions require the full
pressure capability of the tubing.
Maximum allowable metal tube wall
thickness for use with Poly-Flo (R) fittings:
1/16", 1/8", 3/16" O.D. - no limitation;
1/4" O.D. - .035"; 5/16",
3/8", 1/2" O.D. -.049".
