‘Polished Ring’ Pump & Stim Cylinder

This Bi Polar vacuum cylinder is fitted with two conductive aluminium ring electrodes – base & glans. The 50mm tube has a 40mm internal diameter electrode, and the 60mm tube a 50mm internal diameter electrode. The lower section is available in a range of different lengths and additional lengths are available for £22. Simply choose an internal diameter and a length for the lower section. Scroll down to the full product description for information on sizing and electro-stimulation.

Sizing:

Internal diameter (50mm or 60mm): In our hand pump cylinders 50mm is by far the standard size.  Due to the way hand-pumping works the sizes are not that critical - as long as the penis will fit inside the acrylic tube when erect, with room to grow during pumping. 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 mid point of the polished ring electrode is 35mm from this point. The length chosen should be the length closest to that of the erect penis, measured from abdomen to tip. This enables the head of the penis to be drawn into the upper ring electrode when pumped. Sizing is not an exact science as some people extend more or less than others. If you have used a hand pump cylinder before, that is a useful guide.

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

BI-polar E-stim:

The 'Polished Ring' cylinder is bi-polar and can therefore be used on its own. If you are new to Electro-Stimulation you can learn more on our FAQ page.
