The PPE 115901100 Silicone Coupling is crafted as a direct replacement for your 2011-2016 GM 6.6L Duramax LML. High-performance and competitive applications can place immense stress on factory hoses. PPE's hoses are engineered to exceed the quality of OE components, handling the increased pressures of racing and competition.

Each PPE Performance Silicone Hose is reinforced with five plies of polyester fibers, ensuring exceptional durability. The fluorocarbon lining offers superior lubricity and chemical resistance, while the silicone rubber construction allows the hose to withstand constant boost pressures from -76°F to +437°F. In essence, PPE Performance Silicone Hoses will not blow out like stock hoses.

PPE's silicone hoses are resistant to fuel, oil, and chemicals, as well as UV and ozone exposure. These hoses are built to endure the extreme conditions imposed by heavy usage. With multiple sizes and configurations available, there is a PPE Performance Silicone Hose suited for every design application.
