Hose, 40 mm

An amazingly corrugated hose  ideal for pond-type Happet filters. Suitable for a pond, pond or pool. 
It fits perfectly with the outputs and inputs of devices such as filter, UV lamp and pump. It is very  durable and flexible , which is an important advantage, especially when the connections do not run in a straight line.
The hose is easy to keep clean and does not oblate with algae inside.
