It is made from a durable PVC material that is resistant to kinking, cracking, and UV damage. The hose is black in color and has a corrugated exterior, which gives it added flexibility and makes it easier to route through tight spaces. It is typically used for connecting filters, pumps, and other equipment in a pond or water feature, as well as for creating waterfalls and streams. The hose is also commonly used in aquaculture and fish farming.

This hose is a lightweight PVC hose, reinforced with a rigid crush resistant white PVC helix. It is tough, flexible and extremely durable under normal operating conditions. The cross section is maintained even when highly flexed. Minimum frictional loss is achieved by the smooth bore. The corrugation in the hose gives it strength and flexibility, allowing you to turn tight corners without it kinking.
