Description

The Pacific Performance Engineering 515454003 is a universal silicone hose designed for demanding applications. It features a 5-ply Nomex reinforced fiber construction for toughness and a fluorocarbon lining for improved lubricity and chemical resistance. This hose can handle temperatures ranging from -76 to +437 degrees Fahrenheit and withstands constant boost pressures.

The silicone rubber construction ensures structural integrity under high boost, preventing blow-outs common with stock hoses. It is resistant to fuel, oil, and chemicals, as well as UV and ozone, making it suitable for extreme conditions and heavy-duty use. The 6mm wall thickness requires hose clamps to be 1/2 inch larger than the hose ID for a proper fit.
