    Eliminating ECD.

    When creating our Green Stripe® heater hoses, we wanted to tackle the leading cause of hose failure: electrochemical degradation, or ECD. This occurs when the hose, hydraulic fluid, and engine/radiator fittings form a galvanic cell or "battery," creating a chemical reaction that allows micro-cracks to form in the hose tube. Fluid seeps into these cracks or striations and breaks down the reinforcement, leading to hose failure and, ultimately, roadside breakdowns.

    We worked to engineer our EPDM heater hose material compound with superior electrochemical resistance, so your Gates® hoses will last longer and keep your engine systems running stronger.

    Features and Benefits

    • Reduces water loss from water permeating the hose wall and cover.
    • Approved for marine applications.
    • Caution: Do not use for fuel or oil transfer applications.
