CT-228 3.0" Colon Tube

The CT-228 represents the absolute pinnacle of size and capacity in our custom silicone colon tube lineup. Measuring a monumental 228 on the French scale with a massive 3.0" (76mm) outer diameter, this heavy-duty instrument is engineered strictly for advanced expert users who require the maximum possible structural presence. Hand-cast from our premium medical-grade Platinum-Cure silicone, the CT-228 delivers an unyielding physical seal and unparalleled anchoring stability.

The CT-228 allows you to select your ideal length, 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 3.0" (76mm / 228 French) outer diameter throughout the main body of the tube.

• Available Lengths: Scaled to your exact specifications, starting at 24'' and stepping up incrementally by 4'' to a whopping 40” total length. Also, we have made the GBR-228 16", a shorter product with very similar dimensions.

• Smooth Tapered Tip: Begins with a manageable 1.0" diameter rounded entry point and gradually, smoothly increases in diameter over the first 10” before reaching the full 3.0" shaft thickness.

• Grip Retaining Ball Flange: Features a high-profile 3.5” primary retaining ball that drops into a 1 ¾” long by 2.5" diameter retention valley, finishing with a final 3.5" ball flange grip base (not intended for insertion). This piece can also be made with no flange at all

👑 Bob's Choice Recommendations

• Elite, Expert Sizing Only: Measuring a full 3.0" in diameter and running up to 40" in length, the CT-228 is an incredibly intense, specialized instrument. Bob strongly emphasizes that this piece requires a tremendous amount of experience to manage safely and is absolutely not suitable for beginners or intermediate users, this piece will be a challenge for the most advanced users.

• The Prime Material Recommendations: For a silicone tube of this extreme thickness and volume, Bob highly recommends selecting our extra-soft #00-20 or #00-50 if you want it more firm. Despite the sheer thickness of the walls, these extra-soft durometers ensure the piece remains remarkably flexible, allowing it to safely yield, conform, and fit to the natural contours, strictures, bends, and curves of your anatomy.

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.
