6mm 5-ply Silicone Hose 2002-2004 GM 6.6L Duramax #4 (d)

Each PPE Performance Silicone Hose is reinforced with 5 plies of Nomex fibers, making them very tough.

The fluorocarbon lining offers better lubricity, being slippery and resistant to chemicals, while the silicone rubber construction ensures they withstand constant boost pressures and temperatures from -76 degrees to +437 degrees Fahrenheit.

PPE silicone will maintain structural integrity even when subjected to high boost pressures throughout this temperature range.

In summary, PPE Performance Silicone Hoses will not blow out like a stock hose.

PPE’s Silicone Hoses resist fuel, oil, and chemicals while also being UV and Ozone resistant.

These hoses can handle the extreme exposure that heavy usage puts upon them.

With multiple sizes and configurations, there is a PPE Performance Silicone Hose for every design application.

Drag racing and sled pulling place huge stress on your truck’s silicone hoses in a very short period.

PPE’s hoses were designed to handle the rigors of increased pressures during racing and competition.

Their performance tolerances make them an excellent upgrade for daily driving and the extremes of towing heavy loads.

Note: Due to the 6mm wall thickness, hose clamps must be 1/2 inch larger diameter than hose ID for proper fit.
