Silicone hose / hoses / Silicone hose Red / Hump

Hump silicone hose.

This tube has a waist in the middle of the tube which allows it to flex slightly between the pipes it is mounted. A normal straight silicone hose is quite stiff and flexes therefore very little. In car it can be good to have a slightly flexible hose between a motor and a chassis fixed component. This means that the hump hose can take up a portion of the motor movement.
