This hose is built for endurance and performance in custom coolant plumbing and intake systems. Silicone rubber construction with 4-ply reinforcement makes this hose tough, reliable, and flexible to temperatures from -60°C to +180°C (-76°F to +356°F).
Hand-crafted and quality inspected to the highest European standards. Classic Blue with a smooth, shiny "wipe-down" finish. Pre-cut to 4 inches (100mm) long, just the right length to connect two tubes in your cooling system. The 1.75 inch ID is designed to slip over a 1 3/4" (45mm) OD tube. This size is rated over 30 psi working pressure and 130 psi burst pressure. Use with our Lined Hose Clamps (Part No. 3613-2.50).
Note: This hose is NOT formulated for use in oil or fuel plumbing applications. It will survive occasional spills and oil leaks, but it will not stand up to continuous exposure to petroleum.
