Pump Addicted Rx7 vacuum penis pump

The Rx7 is a classic penis pump that works on a simple, proven principle: a vacuum system that draws blood into the penis and holds it there with an airtight seal at the base of the shaft. I consider this model one of the essentials in the Pump Addicted range — it is designed for practicality and comfort, with no fuss.

How the vacuum system works

The Rx7's vacuum system allows you to achieve an erection gradually. Once the vacuum is created, the comfortable, airtight seal at the junction of the penis and pubic area keeps the blood in the shaft. Thanks to the sleeve, the seal remains secure, comfortable, and snug without excessive compression. This design is intended to prevent the discomfort caused by models that are too tight or poorly positioned.

Materials and construction

The Rx7 combines silicone and ABS — a common combination for this type of product. The silicone makes the sleeve flexible, while the ABS provides rigidity to the vacuum chamber. The whole unit weighs approximately 300 g (transparent: 315 g, black: 295 g), making it easy to handle without fatigue. Inner diameter: 6 cm — adjust it to your body. In my view, this is a standard size that suits most people.

Compatibility and accessories

Here's what makes the Rx7 interesting: it can be combined with other products in the Pump series. You can add the Pump vibrating ball to increase the pleasurable sensations. You can also turn the pump into a masturbator with the “pleasure sleeve” masturbadora sleeve, available in two sizes — an accessory that completely changes how it is used and creates an optical effect in which the penis appears visually multiplied by 5. That's a major advantage: a basic pump can become several toys depending on what you add. Take a look at our compatible accessories to see what's available.

Variants: transparent vs. black

The model is available in two colors. The transparent version weighs 315 g and offers an appealing visual experience — you can watch the vacuum effect happen in real time. The black version weighs 295 g and provides greater discretion. There is no difference in performance; it comes down to aesthetic preference and storage. Between you and me, the transparent version appeals to those who like observing the process, while the black version is better suited to those who prioritize discretion.

Who is it for?

Who is it for: Men aged 25 to 55 looking for a solution to improve or maintain an erection, or simply explore penis stimulation without electronics. Beginners and experienced users alike — the product is intuitive. Those who enjoy combining multiple accessories will appreciate the Pump ecosystem.

Who is it not for: If you're looking for an electronic solution with integrated vibration, check out our vibrating sex toys. If you need a very compact pump for travel, the Rx7 is bulky (33.5 cm tall in its packaging).

Girlfriend's tip — Clean it with lukewarm water and mild soap after each use, then dry it thoroughly. The airtight seal is the key to its effectiveness — maintain it regularly to prevent leaks.
