Model F 12" & 16"

from $49.00

As our very first dedicated colon nozzle, the Model F remains one of our most popular and trusted designs. Engineered for deeper fluid delivery, its exceptional flexibility allows it to adapt fluidly to your body's natural internal paths.

The defining feature of the Model F is its unique rolling ribbed multi-ball tip. This 4-inch-long section introduces five beautifully rolled, segmented beads that glide in smoothly while providing a gentle tactile presence. The texturing is followed by an extended smooth shaft that leads down to an integrated internal retaining ball and flared base, offering incredible depth control and a secure backflow seal for advanced cleansing regimens.

Anatomical Design & Dimensions:

Dual Length Options: Available in 12.0" and 16.0" overall lengths.
Deep Insertable Length: Provides approximately 11.0" or 15.0" of deep, fully usable insertion depth depending on your chosen model.
Rolling Ribbed Tip: Features a 4.0" long tip comprised of five rolled ribs/balls measuring 1.0" in diameter at their widest points.
Extended Smooth Shaft: A long, uniform trailing shaft measuring approximately 0.875" (7/8") in diameter to minimize pelvic muscle fatigue during deep placement.
Integrated Base Anchor: Features an approximate 1.4" diameter internal retaining ball just ahead of the expanded safety flange to secure the nozzle at full depth and block fluid backflow.

👑 Bob's Choice Recommendations

Experience Level: Because of the deep 11" and 15" reach, the Model F is an intermediate colon nozzle designed for deep-capacity cleansing and is not intended as a standard starter nozzle.
The Prime Durometer Recommendation: For extended tubes of this length, Bob strongly recommends selecting #10. This hardness level offers the perfect balance—giving the long shaft the flexibility it needs to safely navigate internal contours while keeping it firm enough to slide past muscle clenching without buckling.
The Ultra-Pliable Alternative: If you prefer an exceptionally soft, highly compliant, snake-style feel that completely yields to internal pressure, Bob recommends choosing our extra-soft #00-50 composition.

Extended Upgrades: If you require an even deeper reach, please explore our Model CT-63Fr in the Colon Tube section, which starts at 18" and offers alternative barrel or tapered tip profiles.

Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.

Important Safety Disclaimer: Because individual anatomy varies, we cannot guarantee a full fit for all longer or larger diameter pieces. Please use all products with care. By purchasing, you accept full responsibility for safe use. If you experience discomfort, discontinue use immediately.
