The clear Bathmate Hydromax 7 Wide Boy is the wider-chamber version of the Hydromax 7, intended for people who need more internal width while remaining within the maker- and supplier-supported 5–7-inch erect-length range. It is a rigid, manual, water-powered pump for single-user use. The current maker page identifies the exact Wide Boy variant, maker SKU, GTIN, price, and published variant weight; the official guide supplies the operating and safety limits below.

The Wide Boy has a wider chamber than the standard Hydromax 7. Conflicting archived and legacy pages publish different numerical girth limits, so this page does not invent or choose a girth number. Measure fit before purchase and follow the instructions supplied with the received product. If the received label or guide differs, follow the received materials.
Before use
- Read the supplied Bathmate instructions completely. The maker says not to use the device with sickle-cell disease, a history of prolonged erections, a bleeding disorder, or blood-thinning medication, including aspirin.
- Ask a clinician before use if you have erectile-dysfunction symptoms or a condition or medication that may affect circulation, sensation, bleeding, urinary function, the heart, lungs, kidneys, liver, or nervous system.
- Do not use while impaired by alcohol or drugs, if pain sensation is reduced, if you cannot operate the release with your hands, or if you might fall asleep.
- Before first use and after use, wash with warm soapy water, rinse thoroughly, allow to dry, and store dry away from direct sunlight.
Water setup and controlled pressure
- Relax in a warm shower or bath. Keep the testicles completely clear of the sealing area.
- Fill and position the pump as directed in the maker guide. Use the black valve pip in the closed position only while filling in the shower; keep it centered and open at other times.
- Create a comfortable seal and pump slowly and evenly. Use only the minimum vacuum needed. Excessive vacuum or vigorous pumping can cause bruising or injury.
- Every 2–3 minutes, remove the pump, allow retraction, and massage for two minutes. Repeat no more than three cycles in one 15-minute session.
- Never use the pump for more than 15 minutes in any 24-hour period. Remain awake and in control throughout use.
Release and stop conditions
To remove the pump, press the valve cap inward to activate the quick release, then slide the pump off. Stop immediately for severe pain, discomfort, numbness, marked discoloration, bruising, bleeding, swelling, coldness, loss of sensation, or any other concerning change. Release the vacuum and seek medical advice when symptoms are severe, persist, or concern you.
Do not use lubricant with this water-use device, do not chase a specific pressure or size result, and do not treat temporary expansion as a guaranteed or permanent outcome. This page does not make a medical, treatment, enlargement, performance, universal-fit, or FDA-approval claim.
