Gates Flexible Coolant Hose

The Gates Vulco-Flex II Flexible Coolant Hose is a durable, curved radiator and coolant hose. It bends in almost any direction, so one hose can replace many expensive OE molded coolant hoses. Use it as an upper or lower radiator hose or as a general coolant hose. It is also known as a flex coolant hose or Flex-N-Fit coolant hose.

Key Features:

• Improved sealing surface for greater leak resistance
• High flexibility for easy installation
• Bends to severe angles, including multiple planes and angles in one application, without collapsing or kinking
• Built-in spine wire holds the hose in the desired shape, and helical wire reinforcement resists collapse
• Spine wire does not extend into the hose cuffs, which helps the clamp seal positively
• EPDM construction resists heat, ozone, oil and wear
• Performance is similar to SAE 20R5 Class D-2
• Temperature rating up to +257°F (+125°C)
• Installs with standard aftermarket hose clamps

Gates recommends replacing the clamps each time a new coolant hose is installed. This hose is not for fuel or oil transfer applications.

Gates has been an automotive innovator for over a century. Vulco-Flex II hose gives installers a cost-effective replacement for a wide range of curved coolant hoses.
