The HydroMax9 Cushion Ring is a soft cushion ring that is added to your Bathmate HydroMax 9 penis pump.
The insert seals the opening of the pump for even greater efficiency and at the same time protects the testicle area from falling into the pump while you use it.
The kit includes two gaskets made of flexible and soft material. To place them - follow the instructions on the back of the package.
