CT-63 .825" Colon Tube

from $57.00

The CT-63 represents our slimmest, lowest-profile custom silicone colon tube. Measuring 63 on the French scale with an approximate 0.825" outer diameter, this model is specifically engineered for users seeking an extended reach with a narrower, more manageable thickness. Hand-cast from our high-quality, ultra-durable Platinum-Cure silicone, this highly flexible tube balances deep fluid delivery with impressive pliability.

Fully customizable from tip to base, the CT-63 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 slim, highly flexible 0.825" (21mm / 63 French) outer diameter throughout the body of the tube.
Tip Style B (Smooth Taper): Features a gently rounded, low-pressure entry tip that gradually expands up to the standard 0.825" shaft size for effortless navigation.
Tip Style A (Ribbed Ball Style): An advanced configuration beginning with a unique entry taper that steps into a repeating rib and valley profile:
- First Ball: 20.1mm diameter, followed by a 15.9mm valley.
- Second Ball: 20.75mm diameter, followed by a 16.25mm valley.
- Third Ball: 22.15mm diameter, followed by a 17.25mm valley, before settling back to 20.5mm at the main shaft.
1.3" Custom Flange Base: A compact retention style base featuring:
- A 34.25mm first expansion ball, a 22.8mm retention valley, and a 37.5mm final anchoring ball.
1.8" Custom Flange Base: An expanded retention style base featuring:
- A 45.4mm first expansion ball, a 23.7mm retention valley, and a 46.1mm final anchoring ball.

👑 Bob's Choice Recommendations

Experience Level: Thanks to its smaller 0.825" diameter, the CT-63 serves as a highly accessible introduction to long-format colon tubes. It is an excellent choice for beginners (shorter tubes) - intermediate (longer tubes) users transitioning away from shorter nozzles.
The Prime Recommendation: Bob notes that the single most popular—and highly recommended—customer configuration for this tube is our #10 firmness. This specific density provides the ideal functional sweet spot: it delivers just enough column rigidity to make deep insertion smooth and direct, while fully preserving the high flexibility needed to yield to your body's natural contours.

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.
