The Model F was the first colon-style nozzle we produced and remains one of our most popular designs. It has five rounded ribs at the tip, followed by a smooth shaft and a larger retaining ball near the base. The five ribs extend across approximately 4" of the tip and reach about 1" in diameter. Behind them, the smooth shaft is approximately 7/8" in diameter before expanding to the 1.4" retaining ball and base flange.

Details

  • Available lengths: 12" and 16"

  • Recommended insertion: approximately 11" and 15", respectively

  • Ribbed section: 5 rounded ribs over approximately 4"

  • Maximum rib diameter: 1" (25.4 mm)

Color options

Please note

The Model F is a long design with five rounded ribs followed by a smooth shaft and larger retaining section. It is available in two lengths, making it useful if you want the same basic shape with different overall reach.

Anatomy varies, and no single size or shape will work for everyone. Use appropriate lubrication, never force insertion, and stop if you experience pain or significant discomfort. Inspect the nozzle before each use and do not use it if damaged.
