The PPE 115900100 Replacement Silicone Hose is engineered as a direct replacement for the factory hoses in your 2002-2004 GM 6.6L Duramax, ideal for competitive and high-performance applications. High stress from racing and competition can overwhelm factory hoses, but PPE's hoses are designed to surpass OEM quality and withstand increased pressures.

Each PPE Performance Silicone Hose is reinforced with 5 plies of polyester fibers, providing exceptional toughness. The Fluorocarbon lining enhances lubricity and chemical resistance, while the silicone rubber construction ensures durability under constant boost pressures ranging from -76 degrees to +437 degrees Fahrenheit. In essence, PPE Performance Silicone Hoses are built to resist blowouts, unlike standard hoses.

• Resilience: UV and ozone resistant for longevity in harsh conditions.
• Strength: Features a 5-ply, 6mm wall thickness for superior durability.
• OEM Replacement: Directly replaces GM part #15061708.
• Pressure Capability: Works at 70 PSI (BAR 4.8) with a burst pressure of 207 PSI (BAR 14.3).
• Chemical Resistance: Withstands exposure to fuel, oil, and various chemicals.

Note: Due to the 6mm wall thickness, hose clamps must be 1/2" larger in diameter than the hose ID for a proper fit. This hose cross-references to GM part #15061708. Please confirm your application before ordering.
