PPE Performance Silicone Hoses are strengthened with 5 plies of Nomex reinforced fibers, making them very durable. Fluorocarbon lining offers better lubricity, and the silicone rubber construction ensures they can withstand higher pressures and temperatures from -76 to 437 degrees Fahrenheit. In short, PPE Performance Silicone Hoses will not blow out like a stock hose will. PPE’s Silicone Hoses are resistant to fuel, oil and chemicals while also being UV and Ozone resistant. These hoses can handle the extreme exposure that heavy usages puts upon them. With multiple sizes and configurations, there is a PPE Performance Silicone Hose for every design application. Note: Due to the 6mm wall thickness of PPE Silicone, hose clamps must be 1/2 inch larger diameter than hose ID for proper fit.
