Flexible coupling, 4-step: These hoses are made exclusively from high-quality silicone for the best durability and finish. With three layers of Aramid reinforcement they withstand high pressures and temperatures over a long period. The original hoses on a car or lorry are often made of rubber, which not infrequently cracks as it dries out. These hoses have been developed specifically to bend, flex and absorb vibration. They allow movement in any direction without kinking and without stressing the connections. The flexibility of the hose makes it very forgiving of engine movement, for example. Intended applications: - Pressure applications: turbo, intercooler, supercharger. - Suction applications: air filter, intake. Visualisation of bending: Visualisation of compression:
