Gates 18114 Small I.D. EPDM SID Coolant Hose 0.28in ID 12.4in Length

The Gates 18114 is a Small Inside Diameter (SID) molded coolant hose engineered for OE-replacement performance in tight, modern engine compartments. Featuring a 0.28" inner diameter and 12.4" centerline length, this hose is factory-molded to exact manufacturer specifications for a precise, leak-free fit. Configured as a tee-to-engine connection, it is sold individually.

Constructed with an EPDM tube, synthetic fiber knit reinforcement, and an EPDM cover, the Gates 18114 is specifically engineered to resist Electrochemical Degradation (ECD) — the leading cause of coolant hose failure. ECD occurs when the hose, liquid coolant, and engine or radiator fittings form a galvanic cell, creating micro-cracks in the hose tube that lead to coolant leaks and eventual hose failure. Gates' advanced EPDM compound combats this process, extending service life significantly over conventional hoses.
