PPE Power Red Silicone Upper & Lower Coolant Hose Kit (2011-2016 GM 6.6L Duramax) - (119021300
Overview
Refresh and strengthen your LML Duramax cooling system with the PPE Power Red Silicone Upper and Lower Coolant Hose Kit. This direct bolt-on upgrade replaces the factory rubber hoses and plastic “T” fittings with high-quality silicone and stainless components designed for long-term reliability.
Durable 5 mm Silicone Construction
Each hose is built from 5 mm thick premium silicone, nearly twice the thickness of OEM hoses. Inside, 4-ply heat-resistant reinforcement fibers help the hoses maintain shape and strength under elevated temperatures and high coolant pressure - ideal for both stock and performance-built 6.6L Duramax trucks.
Upgraded Stainless Steel “T” Couplings
Factory coolant hose “T” fittings are molded rubber or plastic and often crack at the junctions over time. PPE eliminates this weak point by using TIG-welded, polished 304 stainless steel “T” couplings that deliver exceptional durability and leak-free performance.
Direct Bolt-On Installation
This kit installs just like the factory components - no cutting or modifications required. PPE includes stainless steel clamps to ensure a tight, secure seal that outperforms standard OEM hardware.
Specialty W-Style Worm Drive Clamps
The included W-style inner liner clamps provide 360-degree constant tension with interlocking surfaces that help prevent leaks. Their stainless steel construction offers excellent resistance to moisture, chemicals, and the harsh under-hood environment.
