The PPE 115900900 Silicone Coupling is designed as a direct replacement for your 2011-2016 GM 6.6L Duramax LML. High-performance and competitive applications can put substantial stress on the factory hoses in your truck. PPE's hoses are engineered to far exceed the quality of OE components, handling the rigors of increased pressure in racing and competition environments.

Each PPE Performance Silicone Hose is reinforced with five plies of polyester fibers, making them exceptionally tough. The fluorocarbon lining provides superior lubricity and chemical resistance, while the silicone rubber construction ensures they can withstand constant boost pressures ranging from -76°F to +437°F. Simply put, 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 are built to 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# 25869099
