CT-152 2" Colon Tube

The CT-152 stands as a, high-volume powerhouse in our lineup. Measuring 152 on the French scale with a substantial 2" (50.8mm) outer diameter, this model is engineered for advanced users who demand maximum fluid capacity and an intense internal presence.

Uniquely versatile, the CT-152 can be ordered in shorter lengths to serve as an oversized, large-diameter enema nozzle or configured in extended lengths for deep-delivery colon training.

Fully customizable from tip to base, the CT-152 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 robust, thick 2.0" (50.8mm / 152 French) outer diameter throughout the body of the tube.

• Tip Style B (Smooth Tapered): Begins with a rounded 0.875" to 1.0" entry diameter, transitioning into a gentle, smooth taper for approximately 6 to 8 inches before meeting the full 2" shaft thickness.

• Tip Style A (Complex Ribbed): An advanced, multi-stage undulating entry point engineered for progressive placement:

  • Initial Entry: Starts at a 0.75" (3/4") diameter, expanding quickly to a 1.4" first rib and a 1.2" valley.

  • First Rib Cluster: Features a secondary 1.4" rib, a 1.45" rib, and a 1.5" rib.

  • Tapered Mid-Neck: Relaxes into a 2" long mid-shaft section that tapers gently from 1.35" up to 1.45".

  • Second Rib Cluster: Rises into a 1.7" rib, a 1.8" rib, and a final 1.9" rib before swelling smoothly into the full 2" main shaft.

• Flange Base Options: Available with our specialized retention-style oval ball flange or configured with a streamlined, no-flange base depending on your application.

👑 Bob's Choice Recommendations

• Advanced Sizing Only: With a 2" main shaft diameter, the CT-152 is a heavy-volume instrument requiring significant experience to handle comfortably. It is not recommended for beginners or intermediate users.

• The Material Flexibility Rule: Because a 2" thick silicone shaft is naturally heavy and rigid, Bob highly recommends selecting our soft #00-50 options for longer builds. This soft density allows the tube to remain highly flexible, safely form-fitting the contours of your anatomy as it navigates natural strictures, bends, and curves.

• Bob's Length vs. Firmness Guide: To ensure your tube has the perfect balance of column strength and flexibility, match your length selection to Bob’s recommended material configurations:

  • Shorter Builds (20" to 28"): #00-20, #00-50, or #10, depending how firm you prefer it

  • Mid-Length Builds (28" to 68"):   #00-50 this is really the perfect firmness for this piece

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.
