These catheters are made from 100% silicone which is considered excellent when used with ozone. The catheter size is 10FR, or 0.131 inches in diameter.
Important Note: To connect these to tubing properly to a multi-chamber insufflation bag you will need a catheter connection kit. Only one connection kit is needed. If using with any other bag or tubing, you will need a catheter adapter. A free adapter is included with a box of 30.
