FDA Approved Osbon Personal Lubricant plays an important part in the overall function of the System. Proper application of our water-soluble lubricant to the head of the penis and to the open end of the cylinder helps create a good vacuum seal against the body. The lubricant also helps you to load and remove the tension rings. You should use only water-based Osbon Personal Lubricant. Other lubricants may damage the tension rings and other system parts, as well as void your warranty.
