| 2 3/4"; Severe Service Silicone Coolant Hose |
Newer heavy-duty engines with advanced emissions systems (from 2007 to current model year) produce higher under-hood temperatures, requiring the use of silicone coolant hose. In these new low engine-air-flow and high-heat conditions, Gates Silicone Coolant Hose is the perfect product. Gates now offers high-quality 4-ply silicone coolant hose for high-heat (up to 500 deg F) performance in these demanding conditions. - Available in 36" straight sections, 45 degree and 90 degree elbows.
- Premium 4-ply construction.
- High heat resistance material meets or exceeds OE specifications.
- Industry standard blue cover for easy identification.
- Used when hose routing passes near turbo or hot side of the charged air system.
Keep your fleet moving by reducing down time and lowering cost-per-mile.
