SAE J20 R2 Flexible heavy-duty Wire Embedded Type EPDM Coolant System Hoses

This steel wire reinforced radiator hose is made of high-quality rubber materials with excellent wear and chemical resistance. It can withstand high pressure and high temperature working conditions for a long time without deformation or cracking. The internal steel wire reinforcement mesh design ensures that the hose will not expand or burst under high pressure, and the coolant is transferred stably to ensure the continuous and stable operation of the engine.

The wire reinforcement in flexible heavy-duty radiator hoses provides additional strength and durability, allowing the hose to withstand higher temperatures, pressures, and mechanical stresses without collapsing or kinking.


Despite the wire reinforcement, flexible heavy-duty radiator hoses remain flexible and can be easily bent and routed in the engine compartment, allowing for easier installation and routing compared to rigid hoses.
The wire reinforcement in these hoses prevents collapsing under vacuum conditions, ensuring continuous coolant flow and preventing coolant system malfunctions.


The wire reinforcement in heavy-duty radiator hoses allows them to handle higher pressures, making them suitable for heavy-duty applications and high-performance vehicles.
Due to their enhanced durability and resistance to mechanical stresses, flexible heavy-duty wire embedded type radiator hoses have a longer service life compared to standard hoses, reducing the frequency of replacements and maintenance.
