Review on Saim 20-Feet Flexible Air-Line Tubing for Aquariums (Black) - Enhanced SEO by Tamara Palmer

Very soft and flexible, strong and forms when stretched. Provides a very tight and durable connection to pumps, accessories, valves, no leaks, accidental or unintentional disconnections. Suitable for tight spaces and sharp corners that are problematic for less flexible, heavier wall hoses. Arrived rolled tight, ends broken, unwound, unwound very loosely, hung on a hook, and after a few hours no kinks, no broken ends, no flat spots, no defects whatsoever the length of the tube. He naturally wants to return to his original shape and size. If that describes your intended use, I see no reason why this tube shouldn't serve you well. If wall thickness is more important than flexibility in your setup, then this tube may not be for you. For me and my needs, this material is perfect.
