The length of the sound is adjustable to allow easy insertion to varying depths. The cylinder is bi-polar, with a ring electrode at the base, so it can be used on its own. Simply choose an internal diameter (50mm/60mm) and a diameter for the sound (5mm or 6.35mm). Scroll down for more sizing information.

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 cylinder length is 210mm.

Sound: The sound is available with a diameter of 5mm or 6.25mm (quarter of an inch). The length of the sound is adjustable to allow easy insertion to varying depths.

If you require a different size or would like more information - just email us. You can do this before or after you purchase.

The tube is fitted with a standard ‘click fit’ female connector compatible with hand held vacuum pumps

BI-polar E-stim:

The 'Urethral Sound' cylinder is bi-polar and can therefore be used on its own.
