This hose is built for endurance and performance in custom coolant plumbing applications. Silicone rubber with 3-ply reinforcement makes this hose tough, reliable, and flexible to temperatures from -60°C to +180 degrees C. Hand crafted and quality inspected to the highest European standards. Bright red with a smooth, shiny "wipe-down" finish. Legs measure approximately 4 inches long. Use with our Aluminum Splicing Nipples (Part No. HJ25 and HJ19) and Lined Hose Clamps (Part No. 3613-1.75) to construct the exact bends and lengths you need. 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.
