35mm > 25mm Silicone Hose Straight Reducer Blue

📏 35mm TO 25mm INTERNAL DIAMETER (ID) - Large end 35mm (1 3/8"), small end 25mm (1"). 4.5mm wall, giving an Outside Diameter (OD) of 44mm and 34mm. 127mm long overall. Measure the outside of both pipes you are joining and match them to the two ID sizes. 🔧 JOINS TWO PIPE SIZES - A straight reducer joins two pipes of different sizes in one piece, so no metal adaptor is needed. Typical uses at this size: top and bottom radiator hoses, thermostat housing pipes, and turbo and intake hoses on smaller engines. 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 main coolant circuit and around the turbo, where rubber hoses soften and swell over time. Working pressure 5 bar, burst pressure 15 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 that cover about 34mm on the small end and 44mm on the large end. 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.
