Duramax Heater Hose Outlet Kit

Upgrade your 2017–2019 GM 6.6L Duramax with PPE’s Silicone Heater Hose Outlet Kit. Designed as a direct bolt-on replacement for the factory hose, this kit requires no cutting or modification. It features a molded design that precisely follows the OEM routing for a clean, hassle-free installation. The hose is constructed from 5mm-thick, 4-ply heat-resistant silicone rubber to ensure long-lasting durability in harsh under-hood environments.

Stainless steel connectors provide superior corrosion resistance and long-term reliability, while the anti-abrasion sleeve offers additional protection against chafing and wear.
