PartekPFA/PTFE Products Quick Reference GuideBulletin 4180-QRG/USARevised, May 2005Fluoropolymer Tubing ProductsFluoropolymer tubing products are offered through Atlantic Tubing Operation (A TO). A TO manufactures high quality fluoropolymer tubing that may be used in conjunction with Partek’s PFA/PTFE products. A wide range of products are available in PTFE, FEP, PFA, High Purity PFA, and PVDF. Other materials are available on request. All tubing and pipeare made from 100% virgin resins.Chemical Properties Electrical Properties Mechanical Properties• Resistivity to corrosive agents • Low dielectric constant • Flexibility at low temperatures• Non-solubility • Low dissipation factor • Low coefficient of friction• Long term weatherability • High arc resistance • Stability at high temperatures• Non-adhesiveness • High surface resistance• Nonflammability • High volume resistivityFluid Handling Tubing and PipeHigh Purity T ubingRetractable Coils & Formed ShapesFractional Industrial & Heavy Wall T ubingConvoluted T ubingDual Containment T ubingStriped T ubingWelding & Standard RodT ubing for Air & Water SamplingSchedule 40 & 80 PipeMetric SizesElectrical Insulation TubingSpiral Cut Cable Wrap Convoluted Tubing Heat Shrink TubingProvides harnessing for wires and Allows for insulation of wire bundles “Shrink to Fit” covers for wires, cable while allowing for leads at where sharp bends are required. cables and other components various points.

Round Beading/Miniature Rod (Not Shown)Excellent as a filler in loose bundles of cables, as a pull cord, or cut into pieces as bearings. The smoother finish, greater flexibility, and longer lengths outperform “granular” extrusions. AWG Spaghetti Size Tubing (Not Shown)Provides “Slip On” protection against extreme electrical or chemical exposure or applications where abrasion resistance is critical.Additionally, it has higher mechanical strength at elevated temperatures (to 500° F ).Custom SpecificationsSpecial orders and custom configuration of standard products are available. All Partek products are cleaned, assembled, tested and bagged in a clean room environment.OverviewPartek serves global markets with a broad range of high-quality flow control products, which include Parflare PFA Tube Fittings, Pargrip PFA T ube Fittings, Parbond PFA Fusible Pipe Fittings, PFA Pipe Fittings, PFA Valves, PTFE Valves, PTFE Pressure Regulators, PTFE Flow Meters, PFA Gauge Protectors, PFA Spray Guns, and PTFE Vacuum Generators. Fluoropolymer tubing and pipe are manufactured and offered at the Atlantic T ubing Operation in Chestnut Ridge, New Y ork.This PFA/PTFE Product Digest is offered as a handy reference guide and overview of Partek products. For more information on PFA/PTFE products contact Partek Operation, the Atlantic T ubing Operation, the Parker Information Center toll-free 1-800-C-Parker (1-800-272-7537) or your local distributor.Partek PFA /PTFE ProductsGeneral Product InformationParker Hannifin's Partek Operation facilities manufacture flow control products for use in fluid systems where corro-sion protection is required or where media purity must be safeguarded. The wetted surfaces of all products are of chemically inert, corrosion-resistant PFA, or PTFE.External materials used are anodized aluminum, polyethyl-ene (HDPE), polyvinylchloride (PVC), polyvinylidene fluoride (PVDF), or perfluoroalkoxy (PFA). ABS plastic knobs are used in some products.Durable, leak-free Partek products are used in a variety of applications including semiconductor manufacturing; chemical, food, and pharmaceutical processing; and biomedical and analytical instrumentation.Material PropertiesPTFE fluorocarbon resins, among the most versatile of all plastics, are rapidly becoming the material of choice for applications involving corrosion resistance. The strong interatomic bonds between carbon and fluorine atoms, and the almost perfect shielding of the polymer's carbon backbone by fluorine atoms make the material inert to most industrial chemicals and solvents.PFA, a close relation, has properties rivaling those of PTFE. Its excellent melt-processability permits conventionalthermoplastic molding and high-speed extrusion processing.End Connections (PFA Products )Male Pipe EndFemale Pipe EndPargrip Tube (Ferrule/Gripper)ConnectionParflare Tube ConnectionEnd Connections (PTFE Products )Partek Parflare PFATube FittingsProvides low dead volume, which decrease the possibility of particle entrapment and bacteria growth.Partek Pargrip PFA Tube FittingsPerfect for applications where ease of assembly is a requisite.Partek PFA Pipe FittingsAvailable in a variety of configurations, all with standard NPT threads.Partek Parbond PFA Fusible Pipe FittingsThe leak-free design eliminates threaded connections.Field proven and high cycle life.Parker Hannifin Corporation Partek Operation7075 E.
