Product details:

Our tubing commonly referred to as UL size, US size, UL non-kink, UL kink-free tubing, UL water garden hose, UL pond tubing, and UL corrugated tubing is perfect for use with water gardening, ponds, waterfalls, fountains, aquariums, and fish hatcheries, drains, light farming and gardening and light irrigation. This hose is designed to be used with barbed or insert fittings and appropriate clamps. The US or UL sized tubing is slightly larger than our MM or Metric sized pond tubing. If you are not certain which size to order, it is usually better to order the UL size and build up your fitting or pump outlet since the MM size is smaller and may not fit your application. While it is not as strong and durable as our flexible PVC pipe, it is somewhat more flexible and lighter. It will not collapse due to backpressure or from the reasonable weight from cover material or gravel.
