The PPE 115901000 Silicone Coupling is designed as a direct replacement for your 2011-2016 GM 6.6L Duramax LML. Competitive and high-performance applications can put significant stress on factory hoses. PPE's hoses are engineered to exceed OE quality and handle the increased pressures typical in racing and competition environments.

Each PPE Performance Silicone Hose is reinforced with five plies of polyester fibers, making them extremely durable. The fluorocarbon lining offers superior lubricity and chemical resistance, while the silicone rubber construction ensures they can withstand constant boost pressures from -76°F to +437°F. In essence, PPE Performance Silicone Hoses will not blow out like stock hoses.

PPE's silicone hoses are resistant to fuel, oil, and chemicals, as well as UV and ozone exposure. These hoses can handle the extreme conditions imposed by heavy usage. With multiple sizes and configurations available, there is a PPE Performance Silicone Hose suited for every design application.

• Features:
  • UV and ozone resistant
  • 5-ply, 6mm wall thickness
  • Replaces GM Part# AKE98909
  • Working pressure: 70 PSI (4.8 BAR)
  • Burst pressure: 207 PSI (14.3 BAR)

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

Upgrade to the PPE 115901000 Silicone Coupling for unmatched durability and reliability in your 2011-2016 GM 6.6L Duramax LML.
