63mm ID Red Silicone Hump Hose - AutoSiliconeHoses

📏 63mm (2 1/2") INTERNAL DIAMETER (ID) HUMP HOSE - 5.5mm wall and an Outside Diameter (OD) of 74mm. 102mm long overall with the flexible hump in the middle. Match the ID to the outside of the pipe or outlet it pushes onto. 🔧 FLEXIBLE HUMP COUPLER - The hump in the middle flexes to absorb engine movement and vibration, so joints are not pulled apart or cracked. Typical uses at this size: turbo outlet and intercooler pipework, larger radiator hoses, and induction kits. 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 hot side of a turbo system and on the main coolant circuit. Working pressure 4 bar, burst pressure 12 bar (3:1 safety factor). 🛡️ SAE J20 R3, 4 PLY POLYESTER REINFORCED - Smooth extruded silicone inner with 4 layers of polyester fabric in the 5.5mm 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 74mm (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.
