Description

The Gates 25257 is a Vulco-Flex II Flexible Coolant Hose, designed to provide reliable performance in demanding engine environments. Its construction features a combination of EPDM rubber and steel, offering durability and resistance to heat, oil, and ozone. The hose is engineered with an improved sealing surface, which contributes to greater leak resistance, and its high flexibility ensures an easier installation process. This coolant hose meets SAE 20R5 Class D-2 performance standards and can operate in temperatures ranging up to +257°F (+125°C). It has a uniform inside diameter of 1.25 inches at both ends and a centerline length of 23 inches, making it suitable for a wide variety of applications with minimal inventory requirements. The product is manufactured in Mexico and is not molded. It is important to note that Gates recommends replacing hose clamps every time a new coolant hose is installed to ensure optimal sealing and prevent leaks. Additionally, this hose is not intended for fuel or oil transfer applications and should only be used for coolant transfer.
