Silicone hose

Reduce downtime and lower cost-per-mile
with NAPA Heavy Duty silicone hose.

Current 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 low engine-air-flow and high-heat conditions— such as transit-style school buses with engine front (EF) and engine rear (ER) configurations – NAPA Belts/Hose Silicone Coolant Hose is the perfect product.

NAPA Belts/Hose now offers high-quality 4-ply silicone coolant hose for high-heat (up to 500ºF) performance in these demanding conditions. Available in 350ºF and 500ºF 36” straight sections and 350ºF 45º and 90º elbows, NAPA Belts/Hose Silicone Coolant Hose has the industry-standard blue cover for easy identification. Keep your fleet moving by reducing down time and lowering cost-per-mile.
