Kasco SureSink™ self-weighted tubing is a durable PVC composite available in both 3/8" and 5/8". The hose will not crack during cold weather and will remain flexible. The 3/8" tubing is used for lengths below 300' and is offered to save on purchase price, installation effort, as well as shipping & handling costs. Marks are placed every foot on all weighted tubing to assist with measurements in the field.
