Suction and discharge hoses (also known as suction and delivery hoses) are one of the largest hoses we manufacture in terms of diameter, usually made from a flexible PVC material and containing a PVC helix. The flexibility of these hoses can range from rigid to super flexible, depending on the application and durability needed.

These hoses operate under negative pressures, meaning they are able to draw water, slurries and various other types of substances from a static source, such as a tank or pool. They are resistant to a range of temperatures, depending on the hose, but are commonly designed to withstand vacuum rather than pressure, abrasion or heat. However, the PVC helix, found in a majority of suction hoses, helps to reduce crushing and kinking.
