Detailed Description

The Gates 12043 is a molded HVAC heater hose engineered to match the routing needs of smaller, tighter-fitting engine compartments. Its formed design helps maintain the correct hose path where a straight hose would not follow the original equipment layout. The EPDM material is commonly used in cooling-system service for its durability in heat and fluid exposure.
