Plastic Tubing | General Technical Information for Multitube

Series E Polyurethane Tubing(Instrument grade, FDA and NSF listed) & Series EB (Ultraviolet light resistant)

Energy Products Division flexible 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).

Parflex 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).

Series FRPE Polyurethane Tubing(Flame resistant)

Flame resistant polyethylene is manufactured from a distinctively formulated compound which meets the UL94 V-2 flame classification. It also meets the flame spread, fuel contribution and smoke density requirements of the ASTM E84-81a tunnel test.

Parflex 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 refineries, pulp and paper mills, mines, steel mills and other industries where protection against intermittent flame and hot sparks is necessary.

Suggested operating temperature range is -85°F (-65°C) to +150°F (+66°C).

Series HDPE Polyurethane Tubing

Energy Products Division 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).

Series N Polyurethane Tubing(Flexible)

Energy Products Division flexible 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. Parflex nylon also exhibits extremely low level water absorption. Chemical resistant Parflex nylon tubing has the additional benefits of better flexibility, lighter weight and resistance to flexural fatigue.

NN and NB tubing meets UL94HB flame resistance ratings in wall thicknesses of .033" and greater.

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.

Operating temperatures, depending upon conditions, are -65°F (-54°C) to +200°F (+93°C) continuous.

Testing Specifications for Plastic Tubing

All plastic used in the manufacture of Multitube are subject to rigorous Q.A. inspection and testing prior to shipment. Each tube is pressure tested at not less than 150 psi for 15 minutes without any sign of leakage.

When Multitube assemblies have completed the manufacturing process, each tube is again tested with dry N2 at 125 psi for 5 minutes prior to shipment.

Metal Tubing | General Technical Information for Multitube

Copper and Stainless Tube

Pressure data for temperatures above 200°F are included for reference only. Plastic coated tubing should not be used at temperatures exceeding approximately 80°C due to the PVC (or PE) jacket employed.

Copper - Armored Tubing

Pressure data for temperatures above 200°F are included primarily for where the tubing must withstand higher ambient temperatures. The assembly should not be used at temperatures exceeding approximately 80°C (176°F) due to the PVC tapes and jackets employed. Consult the Division if higher temperatures will be encountered.

Copper - Jacketed Tubing

Pressure data for temperatures above 200°F are included primarily for where single runs must withstand higher ambient temperatures than the Multitube bundle. The Multitube bundle should not be used at temperatures exceeding approximately 105°C due to the PVC jacket employed. Consult the Division if higher temperatures will be encountered.

Stainless Steel - Jacketed Tubing

Testing Specifications for Metal Tubing

All metal tubes used in the manufacture of Multitube are subject to stringent magnetic analysis using a special eddy current tester. Each tube, after eddy current analysis, is pressure tested at not less than 250 psi for 15 minutes without any sign of leakage. When Multitube assemblies have completed the manufacturing process, each tube is again tested with dry N2 at 250 psi for 5 minutes prior to shipment.

Multitube Instrumentation Tubing Products Chemical Compatibility Guidelines

The Fluid Compatibility Guides below are simplified rating tabulations based on immersion tests at 75F. Higher temperatures tend to reduce ratings. Because the final selection depends on pressure, fluid and ambient temperature, and other factors not known to Parker Hannifin Co. or Motion & Flow Control Products, Inc., no guarantees are expressed or implied.

Ratings do not imply compliance with specialized codes such as FDA, NSF, AGA or UL, and do not cover possible fluid discoloration taste or odor effects. For conveying foodstuffs, use FDA sanctioned materials, and for potable water, use NSF listed materials. For chemicals not listed, or for advice on particular applications, please consult Product Engineering at Parker Parflex Division, Ravena, OH.

Compatiblity Ratings Codes

G = Good to Excellent: Little or no swelling, tensile or surface changes. Preferred choice.

L = Marginal or Conditional: Noticable effects but not necessarily indicating lack of serviceability. Furthter testing suggested for specific applications. Very long-term effects such as stiffening or potential for crazing should be evaluated.

P = Poor or Unsatisfactory: Not recommended without extensive and realistic testing.

- = Not Tested
