Built with premium EPDM rubber, reinforced with synthetic fiber knit and covered with durable EPDM, this hose resists high heat, coolant chemistry, ozone, and vacuum collapse—meeting OEM specs for long-lasting use. Rated to endure −40 °F to +275 °F (−40 °C to +135 °C), it ensures reliability from cold starts to full-tilt track laps.
Technical specifications include a centerline length of approximately 15.6 inches (396 mm) and a 0.25-inch (~6 mm) small inside diameter, ideal for tight-fit engine bays and heater applications.
Compliant with SAE 20R3 Type EC, Class D-1 and D-2 standards, this molded hose maintains integrity under thermal cycling and engine pressures common in spirited driving. Whether you're replacing an aging cracked hose on a daily-driver Miata or upgrading before hard track use, the Gates 18011 delivers precise routing, OEM-grade durability, and peace of mind.
