Parfex fexible polyethylene thermoplastic tubing
is extruded from high molecular weight resin for
increased dimensional stability, uniformity and long-
term strength. Its resistance to environmental stress
cracking greatly exceeds that of ordinary polyethylene
tubing as measured by ASTM D-1693 (10% IGEPAL).
Parfex E series polyethylene tubing is available in
black as well as nine coding colors, as recommended
by the Instrument Society of America. Black (EB)
tubing contains an ultraviolet inhibitor which is
recommended for use in sunlit areas and in close
proximity to high ultraviolet light sources. Ingredients
of E series natural and colored tubing (except EB
series) meet FDA and
NSF 51/61 requirements for food contact
applications. Black polyethylene FDA and NSF 51/61
tubing is available upon special request. All tubing
conforms to ASTM D-1248, Type I, Class A, Category
4, Grade E5.
Suggested operating temperature range is -80°F
(-62°C) to +150°F (+66°C).
Polyethylene Tubing (cont)
Series FRPE: Flame Resistant
Flame resistant polyethylene is manufactured from
a distinctively formulated compound which meets
the UL94 V-2 fame classifcation. It also meets the
fame spread, fuel contribution and smoke density
requirements of the ASTM E84-81a tunnel test.
Parfex Series FRPE tubing is the preferred product
for pneumatic control applications in the heating,
ventilating, air conditioning, energy conservation
industry. It is also suitable for use in petrochemical
plants, petroleum refneries, pulp and paper mills,
mines, steel mills and other industries where
protection against intermittent fame and hot sparks is
necessary.
Suggested operating temperature range is -85°F
(-65°C) to +150°F (+66°C).
Series HDPE: High Density
Parfex Series HDPE is manufactured from high
strength, high density polyethylene. This semirigid
tubing is inherently resistant to most chemicals,
less easily cut or damaged and has a higher burst
pressure rating than series E tubing.
Suggested operating temperature range is -80°F (-
62°C) to +175°F (+80°C).
Nylon Tubing
Series N: Flexible
Parfex fexible nylon tubing is carefully made
from high-grade, abrasion resistant, heat and light
stabilized nylon. Resistance to stress cracking greatly
exceeds that of ordinary nylon tubing. Parfex nylon
also exhibits extremely low level water absorption.
Chemical resistant Parfex nylon tubing has the
additional benefts of better fexibility, lighter weight
and resistance to fexural fatigue. NN and NB
tubing meets UL94HB fame resistance ratings in
wall thicknesses of .033" and greater. Operating
temperatures, depending upon conditions, are -65°F
(-54°C) to +200°F (+93°C) continuous.
Available in natural (NN), red (RED), green (GRN),
blue (BLU), yellow (YEL), and black (NB). Black
tubing is recommended for use outdoors and in sunlit
areas.
