CT-103 1.35" Colon Tube

Measuring 103 on the French scale with a substantial 1.35" outer diameter, this tube is specifically designed for more advanced users who require high fluid capacity and a commanding internal presence. Hand-cast from our durable, medical-grade Platinum-Cure silicone, the CT-103 provides a highly effective anatomical seal and exceptional hands-free stability.

Fully customizable from tip to base, the CT-103 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 & Modular Geometry:

• Main Shaft Diameter: A consistent, large-capacity 1.35" (103 French) outer diameter throughout the body of the tube.

• Tip Style B (Tapered): A sleek, gradually tapered entry design engineered for direct, low-resistance placement.

• Tip Style A (Bumpy): An advanced, textured entry configuration featuring progressive contours designed to gently engage internal curves and maximize fluid retention.

• Flange Options: Tailor your base behavior with two distinct configurations:

  • Integrated Ball Flange Base: A multi-stage anchoring base featuring a primary ball that is approximately 1.7" in diameter, dropping into a 1" diameter retention valley, and finishing with a final 1.8" diameter safety flange measuring approximately 1.25" long.

  • No Flange Base: A streamlined configuration without an integrated base, allowing for an unobstructed, continuous entry profile.

👑 Bob's Choice Recommendations

• Sizing Intermediate: Measuring 1.35" in diameter throughout, the CT-103 is a, larger-volume instrument. Bob strongly cautions that this piece is intended for more experienced users and is not recommended for beginners.

• The Prime Material Recommendation: For a tube with this wide of a profile, Bob highly recommends choosing #10 firmness. This material density strikes the ultimate functional sweet spot: it gives the 1.35" shaft excellent column stability for smooth deep placement, while keeping the bumpy or tapered entry tips comfortably pliable.

• The Extra-Flexibility Alternative: If you want a more compliant, highly flexible internal presence that easily yields to muscle pressure, Bob suggests dropping down to our softer #00-50 composition.

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.
