4mm x 8mm Clear Silicone Vacuum Tubing Rubber Hose Air Water 30 Metre

📏 4MM ID x 8MM OD, 30M LENGTH – 4mm (5/32") internal diameter, 8mm (5/16") outside diameter and 2mm wall, supplied as one continuous 30 metre length (98.4ft, approx. 900g). Choose the ID that matches the spigot you are fitting to. 🔧 MULTI-PURPOSE SILICONE TUBING – for cars, vans, motorbikes, boats and machinery. The 4mm bore suits MAP sensor and boost-control signal lines, wastegate actuator, dump valve and fuel-pressure-regulator vacuum references; also ideal for workshop air lines and low-pressure water transfer. 🌡️ -60°C TO +180°C RATED – continuous operating range -60°C to +180°C with peaks to +200°C. Extruded VMQ silicone to SAE J20 R3 grade stays flexible from cold starts to full engine-bay heat and will not harden, crack or perish like rubber. 🛠️ UNREINFORCED, EASY TO ROUTE – a single wall of silicone with no fabric ply, so it bends round tight routes and seals well on push-on spigots. Made for vacuum, signal, air and low-pressure water lines – not for pressurised coolant, fuel or oil; very tight bends can kink. ⚪ CLEAR SILICONE – clear (translucent) so you can see flow, condensation or blockages at a glance. Trim square with a sharp blade and secure with mini hose clips sized for the 8mm outside diameter.
