FEP Chemical Hose | Parker SW373 Series

    FEP Chemical Hose - FDA, USDA, 3-A - Series SW373


    Series SW373 is a premium quality high pressure, high-temperature suction and discharge hose designed to handle approximately 99.5% of commonly used acids, chemicals, and solvents, as well as food and sanitary materials. The fluorinated ethylene propylene (FEP) tube meets FDA, USDA, and 3-A requirements, will not leach into and contaminate the product being conveyed and features a temperature rating of 300°F (149°C). The hose construction incorporates a dual wire helix that provides full suction capability, kink resistance, and a path to conduct a static electrical charge to ground. The cover is resistant to abrasion, mild chemicals, and ozone.

    WARNINGS!
    „ It is the responsibility of the user to determine if the hose is suitable for the application. Most chemical resistance guides are based on temperatures of 70°F (21°C). Elevated temperatures can change the chemical resistance ratings. Many chemicals will become more aggressive as temperatures increase, reducing the ability of hose compounds to withstand them. Contact Parker for chemical compatibility data at elevated temperatures. If no data exists, users are required to perform compatibility testing at the desired temperature.
    „ At operating temperatures of 125°F and above, only permanently attached couplings should be installed. At any operating temperature, couplings attached with bands or clamps may reduce the working pressure of the hose assembly to less than the maximum rated working pressure of the hose. Refer to the NAHAD Industrial Hose Assembly Guidelines.
