A spiral wound hose consists of two or more sets of helically wrapped high-tensile wire that exhibits exemplary strength, making the hose very strong but also very rigid. The resistance to pressure spikes is exceptionally high, especially compared to a braided hose. However, the bend radius suffers, and spiral wound hose is highly resistant to bending. This effect is especially pronounced with 4- or 6-wire hoses, which are required from many large diameter, high-pressure applications.
