Aquascape® 94000 1.25" x 25' Kink-Free Pipe. Aquascape Kink-Free Pipe is ideal for recirculating water in ponds, waterfalls, and other water features without the use of PVC cement. The internal spiral prevents crushing while the smooth inner wall reduces friction and maximizes water flow. Aquascape Kink-Free Pipe is made in the USA and provides durability and flexibility, making installations quick and easy in a wide variety of applications. Kink-Free Pipe works best when used with traditional barbed fittings and stainless steel hose clamps to form water-tight seals. Aquascape makes it easy to determine pipe diameter by using color coding on the internal spiral of the pipe, making it simple to find the proper fittings for any installation.
