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.

We're in it for the Long Haul.

We do more than engineer our Green Stripe™ belts and hoses to service your fleets up to four times longer than other aftermarket solutions. We build long-lasting relationships with our customers, distributors, and OEM partners along the way. Whether you need help determining which Gates® Green Stripe™ product is best for your application or you need a custom-built solutions, our team of passionate experts is always here to make your business even better.
