The silicone tube is one of the three straps with the ProExtender System. The silicone tube was the very first strap introduced with the classic version of the Proextender.
The silicone tube is still one of the favorite straps and is widely used by customers. The silicone tube strap fits firmly over the protective foam padding supplied with the product to hold the penis, ensuring that the penis is held securely onto the front base plate piece.
As the name suggests, the tube is made up of silicone which is skin-friendly and does not cause irritation or burns.
It is strongly recommended that you always wear protective foam padding supplied along with the product before securing the strap.
