Gates 19188 Premium Molded Heater Hose Small I.D. OE Replacement

The Gates 19188 is a factory-molded, small I.D. coolant hose engineered as a direct OE replacement for today's tighter, more compact engine compartments. With a centerline length of 12-11/16 inches (322mm) and stepped inside diameters of 5/8 in. (16mm) on one end and 3/4 in. (19mm) on the other, this hose connects the heater core to the heater pipe with a precise, leak-free fit.

Constructed with an EPDM tube, synthetic fiber knit reinforcement, and an EPDM outer cover, this hose resists heat, ozone, and electrochemical degradation — the leading cause of premature hose failure. It is suitable for coolant, water, and air applications, and is also approved for marine use.
