• Product Image - Parflex Polyethylene Tubing Instrument Grade

    Parflex 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. Parflex polyethylene tubing is available in black as well as seven 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.

    • Acid and chemically resistant.
    • Flexible.
    • Dimensionally stable.
    • May be used at higher temperatures and working pressures than polyethylene tubing.
    • Resistance to hot water and hot corrosive acids is excellent. Polypropylene tubing will last many times longer than nylon tubing in hot water service.
    • Has water absorption of less than .01%.
    • Has good resistance to vegetable oils.
    • Has excellent resistance to environmental stress cracking.
    • Available in white, UV-resistant black and special NSF black.
    • PPB series tubing has superior ultraviolet resistance.
    • White and NSF black polypropylene meet FDA and NSF-51 requirements for food contact and potable water.
    • PP NSF listed only upon special request.
    • NSF black polypropylene tubing is available upon special request. Add -NSF suffix to PPB part number.
    • The recommended operating temperature range for service at rated pressures with compatible fluids is 0°F (-18°C) to +200°F (+93°C).
