57mm > 51mm Silicone Hose Straight Reducer Red

📏 57mm TO 51mm INTERNAL DIAMETER (ID) - Large end 57mm (2 1/4"), small end 51mm (2"). 5.5mm wall, giving an Outside Diameter (OD) of 68mm and 62mm. 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: 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 4.3 bar, burst pressure 13 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 that cover about 62mm on the small end and 68mm on the large end. Red silicone gives a bold race-style look that makes joints and clips easy to check. Also available in other colours and sizes.
