102mm 4" ID Silicone Straight Hose Joiner Coupler 75mm Length Blue Air Intake & Induction Ducting 4-Ply, 5.5mm Wall, 113mm Outside Diameter Short Joint, Tight Engine Bays -60C to +180C

📏 102mm (4") ID x 75mm STRAIGHT COUPLER - 102mm internal diameter, 5.5mm wall and 113mm Outside Diameter (OD). The 75mm length makes a short joint for tight engine bays. Push it over two 102mm pipes or spigots of the same size to make a sealed inline joint. 🔧 BUILT FOR AIR INTAKE & INDUCTION DUCTING - at 102mm bore it suits air intakes, induction kits, cold air feeds and large-bore ducting, on cars, vans, motorbikes, 4x4s, trucks, tractors, plant and industrial machinery. 🌡️ HIGH TEMPERATURE SILICONE -60°C to +180°C - stays flexible through extreme heat and cold and resists ozone, UV and moisture, so it will not harden, crack or perish the way ageing rubber hose does. 🛡️ 4-PLY POLYESTER REINFORCED - 4 layers of polyester fabric inside a 5.5mm silicone wall hold the 102mm bore round under boost pressure and vacuum, with a smooth inner surface for clean airflow and coolant flow. 🔵 BLUE GLOSS FINISH - a smart blue silicone joiner for a tidy engine bay. Cut with a sharp blade for a shorter joint, and secure each end with a hose clip sized for the 113mm Outside Diameter (OD). Also available in red and black.
