Universal Silicone Pump Sleeve - Perfect vacuum together with your penis pump!

Universal Pump Sleeve closes tightly around your penis pump and fits all cylinders with a diameter up to 7,5 cm.

When it closes completely tightly, a vacuum is created that is needed for your penis pump to work in the best possible way.

The sleeve measures 6x6 cm and is made of 100% pure silicone and the flexible material makes this pump-sleeve stretchable when needed.
