Green Stripe® 2-Ply Straight Coolant Hose

Gates® Green Stripe® 2-Ply Straight Coolant Hose stick hose is designed for demanding heavy-duty coolant/air applications. The two-ply bias fabric construction maximizes flexibility and strength, with an advanced EPDM tube and cover that resist "cold water leaks," and remain soft and pliable, even under adverse operating conditions.

  • Temperature: –40°F to +257°F (–40°C to +125°C)
  • Exceeds SAE 20R1 Type EC (Class D-1 Tube, and cover, Standard Wall)
  • Cover marked in one-inch increments to facilitate approximate cut lengths
  • Engineered with compounds which resist electrochemical degradation
  • Approved for marine applications
  • Caution: Do not use for fuel or oil transfer applications
  • Note: For a maintenance-free connection, use PowerGrip® SB Clamps

Eliminating ECD.

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

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

Inspecting Your Coolant Hose.

As part of our Be System Part initiative, we recommend regularly inspecting your critical vehicle systems, including your cooling system and hoses, at around 60,000 miles. As your coolant hose begins to age, the constant transfer of chemical fluids will corrode your hose from the inside out. When inspecting your coolant hose, there are a few simple signs that it's ready for replacement:

Press for Soft Spots. The radiator hose is naturally rigid, and any soft spots along the hose body indicates the inner material has begun to break down. Firmly press on the hose body to feel for potential deteriorations.

Check the Ends and Fittings. Look for cracks around the hose end, especially near the hose clamps.

Feel for Bulges. Run your hands along the hose body to feel for protruding materials, which indicate a rupture within the hose that will eventually lead to failure.
