Rubber Hose Support Springs

These stainless steel internal support springs are used to optimize flow through a soft rubber hose. They are commonly used in 2 different scenarios. 1. When rubber hoses require a tight radius bend, they will often kink. This "restriction" can be avoided by using these springs. 2. When a rubber hose experiences a high amount of vacuum, they can collapse. This is more common with larger hoses than smaller hoses. This "flattening" can be avoided by using these springs.
