The PPE 515303003 3" Silicone Coupler is designed to handle the rigors of increased pressure from your high performance engine. Each PPE Performance Silicone Hose is strengthened with 5 plies of polyester reinforced fibers making them very tough. The Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures that they can withstand constant boost pressures from -76 degrees all the way to +437 degrees Fahrenheit. In short, PPE Performance Silicone Hoses will not blow out like a stock hose will.
3" ID x 3" Long
5-Ply, 6mm Wall Thickness
