The CT-228 is a 3.0" (76 mm / 228 French) diameter colon tube designed for experienced users looking for one of our largest tube sizes.

It is available in 24", 28", 32", 36", and 40" lengths. You can also choose the bore size, silicone firmness, and color. The CT-228 can be made with the standard flange arrangement or without a flange.

Smooth Tapered Tip

The CT-228 uses a smooth, rounded tip that starts at approximately 1.0" in diameter and gradually increases over the first 10" before reaching the full 3.0" shaft diameter.

Retention Flange

The standard base has a 3.5" retention ball followed by a 1.75"-long, 2.5" diameter valley and a final 3.5" base section.

The CT-228 can also be made without a flange if that is what you prefer.

Choosing your silicone firmness

Because of the CT-228's 3.0" diameter, silicone firmness makes a noticeable difference in how the tube behaves.

For this design, Bob recommends #00-20 (Soft) for maximum flexibility. If you prefer a somewhat firmer tube, #00-50 is also available.

If you're unsure which firmness to choose, we recommend ordering our silicone firmness samples first.

Color options

#18 and #30 are available in pure translucent.

#00-20, #00-50, and #10 are translucent white base materials and can be mixed with standard colors.

Please note

The CT-228 is one of our largest designs and is intended for very experienced users. The longer versions add considerably to the overall size of the piece.

Everyone's anatomy is different, and we cannot guarantee that a particular length or diameter will be suitable for everyone.

Use appropriate lubrication, never force the product, and stop if you experience pain or significant discomfort. Inspect the silicone before each use and do not use the product if it is damaged.
