Our ‘Mushroom head’ vacuum cylinders have a close fitting lower stage and a wider upper stage. This focuses sensation and enlargement on the head of the penis. The ‘SeriousKit’ design includes two of our precision machined polished aluminium ring electrodes. The ring electrodes have the same diameter as the lower stage.
Just choose an internal diameter and length. The length refers to the distance from the base of the cylinder to the point in the upper electrode where the diameter starts to increase. Additional lower sections are £22 each. Scroll down for more sizing information.
Internal diameter of lower stage (40mm or 50mm): In this model of hand pump cylinder 40mm is by far the standard size (this is because the 'Mushroom Head' cylinder is designed to have a closer fitting lower stage in order to encourage maximum growth for the head of the penis - you must still fit comfortably inside the lower stage). Diameter is calculated by dividing circumference by 3.142 (π)
Length: The Length of the lower section is available in 100mm, 110mm, 120mm, 130mm, or 140mm lengths. The length refers to the distance from the base of the cylinder to the point in the upper electrode where the diameter starts to increase. The ‘best fit’ is to have a lower stage that fits close to the shaft but is short enough to allow the head of the penis to sit in the upper section. The length chosen should be the length closest to that of the erect penis, measured from the abdomen to the base of the head of the penis. It is important that the lower stage is not too long.
If you require a different size or would like more information - just email us. You can do this before or after you purchase.
Additional lower lengths are available to ensure correct sizing or for use with multiple players.
The tube is fitted with a standard ‘click fit’ female connector compatible with hand held vacuum pumps
The 'Polished Ring' cylinder is bi-polar and can therefore be used on its own.
