PPE Intercooler Piping Silicone Hose Kit (2002-2004 GM 6.6L Duramax LB7) - (115910204
Overview
The PPE Intercooler Piping Silicone Hose Kit is engineered specifically for the 2002-2004 GM 6.6L Duramax LB7, offering a durable and high-performance replacement for aging factory rubber hoses. Built to handle extreme boost, heat, and chemical exposure, these hoses deliver long-lasting reliability for stock and modified applications.
Heavy-Duty 5-Ply Construction
Each hose features a 5-ply, 6mm wall design reinforced with Nomex fibers for exceptional strength. The fluorocarbon lining provides superior lubricity and resistance to oil, fuel, and chemical breakdown, ensuring consistent performance under demanding conditions.
High Pressure & Temperature Capability
Designed for high-boost environments, these hoses support a working pressure of 70 psi and a burst pressure of 207 psi. They maintain structural integrity across a wide temperature range from -76°F to +437°F, making them ideal for towing, racing, and heavy-use applications.
Built for Durability
PPE silicone hoses outperform standard rubber by offering better flow, improved flexibility, and increased resistance to UV exposure and ozone. Whether you're daily driving or pushing your LB7 hard at the track, these hoses are designed to withstand rapid pressure changes and extreme operating conditions.
