Constructed from an EPDM tube and cover with a synthetic fiber knit reinforcement, this hose resists typical causes of failure—vacuum collapse, ozone, heat and electrochemical degradation—while meeting major industry specifications for replacement service. Choosing a purpose-shaped Gates molded hose reduces installation time and helps restore proper coolant flow and sealing where a standard straight hose won't fit.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hose match OEM fit and routing?\u003c\/h3\u003e\n\u003cp\u003eThe Gates 23460 arrives pre-shaped to the exact contours of the OE part it replaces, eliminating the need to bend or trim during installation. Precise molding maintains correct hose length, bend radius and port alignment so clamps seal reliably and the hose avoids kinking or contact with moving components.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-shaped geometry mirrors specific OE connectors and bends\u003c\/li\u003e\n  \u003cli\u003eDimensional tolerances designed for drop-in replacement\u003c\/li\u003e\n  \u003cli\u003eConsistent inner diameter for uninterrupted coolant flow\u003c\/li\u003e\n  \u003cli\u003eOptimized for proper clamp placement and sealing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction improve durability?\u003c\/h3\u003e\n\u003cp\u003eThis molded hose uses an EPDM inner tube and cover—materials selected for resistance to heat, ozone and common coolant additives—combined with a synthetic fiber knit reinforcement layer.
