8mm (5/16") Internal Diameter Red Silicone Radiator Straight Hose 1 Metre Length Universal Tube

📏 8mm (5/16") INTERNAL DIAMETER (ID) 1 METRE STRAIGHT HOSE - 4.5mm wall and an Outside Diameter (OD) of 17mm. 1 metre long (about 39 inches), cut to the length you need. Match the ID to the outside of the pipe or outlet it pushes onto. 🔧 CUT TO ANY LENGTH - A straight 1 metre length you can cut to exactly the size you need with a sharp knife. Typical uses at this size: vacuum lines, breather and crankcase vent hoses, boost and wastegate actuator lines, and coolant bleed pipes. For air, water and coolant; not suitable for fuel or oil (choose our Fluoro Lined fuel and oil hose for those). 🌡️ -50°C TO +180°C OPERATING RANGE - Rated -50°C to +180°C with a peak of +250°C, so it copes close to the exhaust, turbo or manifold where small rubber lines go hard and crack. 🛡️ SAE J20 R3, 3 PLY POLYESTER REINFORCED - Smooth extruded silicone inner with 3 layers of polyester fabric in the 4.5mm wall, so it holds its shape under pressure and resists swelling. The silicone resists ozone, UV light, weathering and ageing, so it lasts outdoors and in the engine bay without perishing. 🔴 RED - FITTING TIP - Push the hose fully onto the pipe, then use hose clips whose range covers about 17mm (the Outside Diameter). Red silicone gives a bold race-style look that makes joints and clips easy to check. Also available in other colours and sizes.
