25mm (1") Internal Diameter Blue Silicone Radiator Straight Hose 1 Metre Length Universal Tube

📏 25mm (1") INTERNAL DIAMETER (ID) 1 METRE STRAIGHT HOSE - 4.5mm wall and an Outside Diameter (OD) of 34mm. 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: heater matrix feeds and returns, expansion tank and overflow pipes, and small radiator and water pump hoses. 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 on the cooling and heater circuit, which runs hot every time the engine is up to temperature. Working pressure 5.5 bar, burst pressure 16.5 bar (3:1 safety factor). 🛡️ 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. 🔵 BLUE - FITTING TIP - Push the hose fully onto the pipe, then use hose clips whose range covers about 34mm (the Outside Diameter). Blue silicone gives a bright show-car look that stands out under the bonnet and is easy to trace. Also available in other colours and sizes.
