This Is The Hose Upgrade Your Duramax Deserves

If you're building a truck that works as hard as you do, the PPE 115901100 Silicone Hose is one of those smart upgrades that makes a real difference over time. Stock rubber hoses are known to crack, split, and fail under heat or boost, especially if you're towing heavy or running a tuned setup. This PPE hose is built for serious durability, with a 5-ply polyester-reinforced design that holds strong under high pressure without giving out. It's made to thrive in everything from daily use to race-day abuse, whether you're pulling a fifth-wheel trailer or lining up at the sled pull. The high-temp silicone construction gives you a huge temperature range, so you're covered from frigid mornings to long climbs in scorching summer heat. And thanks to the internal fluorocarbon lining, you don’t have to worry about fuel or oil breaking it down over time. If you're tired of swapping out hoses or dealing with weak links in your boost system, this is the one-and-done solution you've been looking for.

Built To Handle Heat Pressure And Real World Abuse

The PPE 115901100 Silicone Hose is engineered specifically for 2011–2016 GM 6.6L Duramax LML trucks and is built to outlast and outperform factory hoses in demanding conditions. Its construction features five layers of polyester-reinforced silicone, giving it exceptional burst strength and long-term durability under constant boost. Operating temperatures range from -76 to 437 degrees Fahrenheit, ensuring the hose remains stable and flexible whether your truck is idling in cold weather or hauling under full load in the summer. The inner lining is made from a fluorocarbon material that resists degradation from fuel, oil, and chemical exposure, common causes of failure in standard silicone hoses. It’s also highly resistant to UV and ozone damage, making it ideal for trucks that spend their lives outdoors or on the job site. One important detail to note is the 6mm wall thickness, which provides added strength but requires clamps that are half an inch larger in diameter than the hose ID. Whether you're replacing a worn-out factory hose or upgrading for performance, this PPE hose delivers reliable, long-term performance you can count on.
