Nonconductive EPDM coolant hose —7997 series.
7997-series nonconductive EPDM coolant hose with E-glass outer protection. 500°C denotes external radiant exposure, not conveyed-fluid temperature. Select coolant temperature, radiant exposure duration and electrical requirements separately. A nonconductive compound does not establish an assembly dielectric certification.
