Pump Addicted Rx5 ergonomic vacuum penis pump

The Rx5 pump works on a simple but effective principle: creating a progressive vacuum that concentrates blood in the penis, independently of natural erection. I consider it one of the essentials for anyone looking to improve their performance or manage mild erectile dysfunction. For me, the key advantage here is the seal’s ergonomics—it must be both airtight AND comfortable, which is not easy to achieve with this type of product.

Vacuum system and airtight seal

The heart of the product is the comfortable, airtight seal positioned at the base of the body, where the penis meets the pubic area. This seal maintains the vacuum without excessive compression—that is the difference between a pleasant pump and one that hurts. Thanks to the soft silicone sleeve, the seal stays firm while remaining comfortable throughout use. The progressive vacuum system allows blood to accumulate gradually, providing better endurance and a longer-lasting erection.

Material and construction

ABS body (rigid plastic) combined with silicone for the seal and sleeve. The ABS provides structural strength and either transparency (transparent version) or opacity (black version). The silicone seal should be cleaned regularly to prevent residue buildup. Between us, I prefer recommending this type of construction over PVC—ABS and silicone age better and do not release a chemical odor over time.

• Insertable length: 23 cm
• Inner diameter: 5.5 cm
• Weight: 350 g (transparent) / 330 g (black)
• Material: ABS + silicone
• Waterproof (cleaning with lukewarm water recommended)

Transparent and black versions

The choice between transparent and black is primarily about aesthetics and discretion. The transparent version offers an interesting optical effect (as mentioned in the specifications, the penis may appear visually enlarged during use). The black version is more discreet when stored. Both versions have the same technical specifications and seal ergonomics. The weight varies slightly (350 g vs. 330 g), which does not affect use.

Accessory compatibility and enhancements

The real strength of the Pump Addicted system is its modularity. You can pair the Rx5 with:

• Pump vibrating ball (sold separately)—increases pleasurable sensations
• Pump masturbator sleeve (two sizes available)—turns the pump into a masturbator while amplifying the vacuum effect
• Water-based lubricants—compatible with silicone and ABS

Who it is for and who it is not for

Who it is for: Men seeking enhanced erectile performance, those managing mild erectile dysfunction, or anyone simply curious about exploring a different kind of stimulation. The vacuum system is effective, and the seal’s ergonomics make it accessible even for beginners—you do not need to be an expert to use it. The 5.5 cm diameter suits most body types.

Who it is not for: If you are looking for a 100% passive solution without any mechanics, or if you are extremely sensitive to pressure, you should test it first. Some men find the vacuum system too intense at first—in that case, I recommend checking out our other male stimulation solutions or taking the time to adjust gradually.

A girlfriend’s advice— Start with short sessions (5–10 min) to let your body adapt to the vacuum. Use a water-based lubricant on the seal to improve airtightness and comfort. And I’ll be honest: this type of pump requires regular seal maintenance—do not neglect it, as this extends the product’s lifespan.
