Catheter funnel ends are the ends of many intermittent catheters where urine exits the catheter tube. On many catheter products, the funnel end is also color-coded to help identify the catheter’s French size.
Below, we answer common questions about catheter funnel ends, catheter funnel colors, and what to check if you are unsure of your catheter size.
What is a Catheter Funnel End?
The catheter funnel end is the end opposite the insertion tip. After urine drains from the bladder through the catheter eyelets and tube, it exits through the funnel end into a toilet, urinal, collection bag, or other receptacle.
You can learn lots more about the different parts of a catheter, including insertion tips, eyelets, and more, in our complete guide to parts of intermittent catheters.
What Are Catheter Funnel Ends Used For?
Catheter funnel ends are used to direct urine flow out of the catheter.
Depending on the catheter brand and style, the funnel end may also help with gripping, connecting to compatible drainage supplies, or identifying catheter French size by color.
Some coudé catheters may also include a guide stripe down the length of the catheter or a notch or raised marker near the funnel to help indicate the position of the curved catheter tip.
If you need to use a coudé catheter, follow your healthcare provider’s instructions for proper catheter use and positioning of your insertion tip.
What Do Catheter Funnel Colors Mean?
Many intermittent catheters use a universal funnel color-coding system to help identify the catheter’s French size. French size (Fr) refers to the outside diameter of a catheter tube.
For example, a green catheter funnel commonly indicates a 14 Fr catheter. However, not all catheter products use color-coded funnels, so always check your catheter packaging if you are unsure of your size.

Why Do Some Catheters Not Have Funnel Ends?
Most intermittent catheters have funnel ends, but some products are designed without a traditional funnel. These may be called luer end catheters or whistle-tip catheters. Instead of a funnel, the catheter’s end is an open tube.
Some people may prefer this style because of the product design, packaging, or how it fits their routine. If you are interested in discreet catheter options, you may also want to learn about pocket catheters.
How Do I Know What Catheter Size I Need?
Your prescribing healthcare provider should determine the appropriate catheter French size for your anatomy and medical needs. If you are unsure what size catheter you currently use, check the packaging or contact your catheter supplier to review your product information.
