CT-190 2.5" Colon Tube

The CT-190 stands as a very high volume profile in our custom silicone colon tube family. Measuring a monumental 190 on the French scale with a 2.5" (63.5mm) outer diameter, this heavy-duty instrument is engineered strictly for elite, highly experienced users who require maximum structural presence and high-capacity fluid delivery. Hand-cast from premium, medical-grade Platinum-Cure silicone, the CT-190 delivers an unparalleled physical seal and maximum hands-free anchoring stability.

Fully customizable from tip to base, the CT-190 allows you to select your ideal length, tip style, safety flange size, bore size, color, and material firmness to create a piece tailored exactly to your anatomical requirements.

Anatomical Design & Tailored Geometry:

• Main Shaft Diameter: A hearty, ultra-substantial 2.5" (63.5mm / 190 French) outer diameter throughout the body of the tube.

• Available Lengths: Built to your needs, starting at a deep 24'' and stepping up incrementally by 4'' up to a maximum total length of 44”.

• Tip Style B (Smooth Tapered): Begins with a slim 3/4" (12mm / 36 French) smooth entry point and gradually increases in diameter over the first 8” until it smoothly meets the maximum 2.5" shaft diameter.

• Tip Style A (Graduating Ribs): An advanced, textured entry configuration featuring three massive graduating expansion zones and valleys to ease placement:

  • First Rib: Tapers from the tip up to 1.9” (48.3mm / 145 French), followed by a 1.6” (40.6mm / 122 French) valley.

  • Second Rib: Reaches 2.0” (50.8mm / 152 French), followed by a 1.7” (43.2mm / 130 French) valley.

  • Third Rib: Expands to 2.1” (53.3mm / 160 French), followed by a 1.9” (48.3mm / 145 French) valley, before swelling to the full 2.5" shaft.

• Heavy-Duty Retention Flange: Features a robust 2.8” (71mm / 210 French) primary retaining ball, dropping into a 2.0” (50mm / 150 French) retention valley, finished with a final ball grip base (not intended for insertion).

👑 Bob's Choice Recommendations

• Elite Sizing Only: Measuring 2.5" in diameter and up to 44" long, the CT-190 is a monumental piece. Bob strongly emphasizes that this instrument requires a tremendous amount of experience to use and is absolutely not suitable for beginners or intermediate users.

• The Prime Material Recommendations: For a tube of this massive thickness and scale, Bob highly recommends selecting our extra-soft #00-20 or #00-50 options. These extra-soft densities ensure the substantial 2.5" shaft remains remarkably flexible, allowing it to safely yield, form, and fit to the natural contours, strictures, bends, and curves of your anatomy.

• The Firmness Caution: Bob explicitly cautions that choosing anything more firm than #00-50 for the CT-190 demands an exceptional, expert level of experience due to the sheer structural presence of a 2.5" thick silicone shaft.

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.
