Simple Vacuum cups for your Vacuum Kit. If you ever lose your regular cup, damage it, or just need to size up. These will receive updates as time goes on.
Please measure your flaccid glans to get the proper sizing for cup. Please chose a size that will allow for at least a quarter of the circumference. All the number numbers should be sized up to suit your expansion numbers. We do recommend you select the next size up if you are already at or near the fullness level.
| Vacuum Cup Size | Imperial Range | Metric Range (cm) |
| COMPACT - 33 mm (Full at 4) | 3.0" – 3.75" | 7.62 cm – 9.52 cm |
| MEDIUM - 38 mm (Full at 4.7) | 3.75" – 4.5" | 9.52 cm – 11.43 cm |
