Features:
If you’re still running stock rubber hoses on your Duramax, it’s not a matter of if they’ll fail under pressure, it’s when. The PPE Performance Silicone Hose is a serious upgrade built for diesel trucks that do more than just cruise around town. Whether you're towing a heavy trailer or putting the hammer down at the track, this hose holds strong when others fold. The 5-ply polyester construction adds real strength where it counts, helping to prevent blowouts and failures when boost pressure spikes. It’s also built to take the heat, literally, with a temperature range from -76 to 437 degrees Fahrenheit. That means you're covered from icy starts in the winter to long climbs under heavy load in the summer. If you're the type who expects more from your truck, this hose delivers reliability and peace of mind with every mile.
Behind the scenes, the PPE 115900500 Silicone Hose is engineered to take the kind of punishment most hoses simply can't handle. It's constructed with five layers of polyester reinforcement for maximum tensile strength and long-term durability, even under high boost conditions. A specialized fluorocarbon lining gives it superior resistance to fuel, oil, and chemical exposure, which is crucial for performance diesels running hard. Unlike factory hoses that get brittle or collapse over time, this one stays flexible without sacrificing structure, even after years of abuse. Its thick 6mm wall also makes it more resistant to pressure spikes and blowouts during sled pulls, drag passes, or heavy towing. The outer material resists UV damage and ozone degradation, so it won’t dry out or crack under the hood. Just remember, because of the added wall thickness, you’ll need hose clamps that are at least half an inch larger than your hose diameter to ensure a proper seal.
