Anatomy of a Penis Pump

The typical penis pump will have five (5) main components including the cylinder, sleeve, hose, pressure gauge, and pump mechanism.

Cylinder

The cylinder is a clear tube or chamber typically made out of acrylic that encompasses the penis during a pumping session. Some cylinders are made out of ABS plastic or glass, and come in various sizes to fit your erect penis size. Many cylinders also have a ruler imprinted or labeled on its body for fast and accurate measuring.

Cylinders should fit your penis size properly for optimal safety and effectiveness. Please view our cylinder sizing charts to find the proper size here.

Sleeve

The sleeve is a silicone or rubber cover used as both a soft padding at the base of the penis and a sealant to reduce air leakage.

While not necessary for a pumping session, sleeves provide a hygienic and comforting barrier between the device and your body that can be easily removed and cleaned.

Hose

The hose is a flexible rubber tube that connects the pump to the cylinder.

Pressure Gauge

The pressure gauge is a digital or analog screen or dial that measures the pressure in the chamber in inHg or kPa.

While the pressure gauge is not necessary and some vacuum devices do not come with one, we would recommend pumps that have them, for greater accuracy and safety.

Pump Mechanism

The pump mechanism is an electric or manual device used to remove air from the chamber to create a negative pressure. The negative pressure then produces an erection or expansion by drawing blood into the shaft of the penis.
