Fluoropolymer Tubing
fluoropolymer-tubing1
Almost totally inert, FLUOROPOLYMER tubing can be used with virtually all industrial solvents, chemicals, and corrosive materials, even at elevated temperatures. It does, however, react with fluorine, molten sodium hydroxide, and molten alkali metals.
FLUOROPOLYMER tubing can be steam or chemically sterilized in-line with any industrial cleaner, solvent, or sterilizing method.
FLUOROPOLYMER’s non-stick property allows transport of viscous, sticky materials without line clogging. It also offers outstanding aging resistance.
PTFE’s translucent white color will vary naturally from lot to lot, however the quality and physical properties do not change. FEP and PFA are clearer and can be heat sealed and heat bonded.
Permanent color striping, etching, and longer-than-listed lengths are available through minimum order. Polyethylene-jacketed, thin-wall fluoropolymer tubing, for low-cost purity, is also available through minimum order.
What is it?
PTFE (Polytetrafluoroethylene) resin is supplied in powdered form, which is mixed, preformed, and extruded into a paste, and then finally tubing. It is translucent white in color.
FEP (Fluorinated Ethylene Propylene) resin is pelletized for its hot-melt extrusion process and is a clear tubing.
PFA (Perfluoroalkoxy) resin is also a pelletized product which is hot melt extruded. It, too, is clear. /Asset/a4199.jpg
Almost totally inert. COILTEF can be used with all industrial solvents, chemicals, and corrosive materials even at elevated temperatures. It does, however, react with fluorine, molten sodium hydroxide, and molten alkali metals.
Fluoropolymer's non-stick property allows transport of viscous, sticky material without line clogging. It also offers outstanding aging resistance.
COILTEF is manufactured through a fabrication process which heat sets the coils. The coils should remain stable up to 200ºF. At higher temperatures the coils will begin to relax and lose their set. If the application involves elevated temperatures, in-house testing is recommended.
COILTEF may be steam or chemically sterilized in-line with any industrial cleaner, solvent, or sterilizing method. Care should be taken with steam sterilization to prevent coil relaxation. Testing is recommended.
COILTEF can be manufactured from 0.085" to 1/2" tubing I.D. The coil diameter can be produced from 3/4" O.D. to 4" O.D.
PFA-formulated COILTEF is available by special order. /Asset/a4201.jpg
Vacuum Service: 29.9 in./Hg.
Bend Diameter: 1/2 of tubing I.D.
Extension/Compression Length Ratio: 2 to 1
Optimal flow is achieved and turbulence minimized by passing fluids through CORRTEF in the direction of the corrugation angles (as illustrated).
CORRTEF is heat sealable, and the cuffs (straight ends) are made to accept standard barbed fittings. The end may be flared or expanded to permit shrink-tight connections.
CORRTEF is manufactured in an industrial atmosphere and should be properly sterilized for dean-flow applications. For optimal cleaning of CORRTEF, the tube should be stretched to its maximum length and held vertically (direction of flow: down). Due to the annular corrugations, it may not be possible to remove all traces of particulate from CORRTEF, even under optimal cleaning conditions. /Asset/a4202.jpg
CONTEF's helical construction aids in self cleaning when flushed with standard cleaning fluids.
The cuffs (straight ends) are made to accept standard barbed fittings. Hose assemblies made to your specifications are available.
PTFE's color will vary naturally from lot to lot, but the quality and physical properties do not change.
FEP CONTEF for longer continuous lengths - up to 500 ft. - is available through custom order.
CONTEF Without Wire:
Vacuum Service: 29.9 in./Hg at 70ºF.
Convolutions are molded into the tubing and will not cold flow into a straight wall under normal conditions.
CONTEF With Wire:
Vacuum Service: 29.9 in./Hg at 70ºF.
For high vacuum applications, CONTEF can be produced with wire on the I.D. /Asset/a4206.jpg
Fluoropolymer Tubing (PTFE, FEP & PFA)
