Gates 19759 Premium Molded Heater Hose 24.3in x 0.75in ID OE Replacement

The Gates 19759 is a premium small I.D. molded heater hose engineered as a direct OE replacement for heater-to-engine coolant circuit connections. Factory-molded to fit today's smaller, tighter engine compartments, this hose delivers reliable performance and a precise, leak-free seal right out of the box.

Constructed with an EPDM tube, synthetic fiber knit reinforcement, and an EPDM cover, the Gates 19759 is built to withstand the demanding conditions of modern cooling systems. It meets SAE 20R3 Type EC Class D-1 and D-2 specifications and is engineered to resist electrochemical degradation (ECD) — the leading cause of premature hose failure. The heat- and ozone-resistant cover further extends service life, even in extreme underhood environments.
