Product specification Penis pump Pump Worx Max Boost — transparent cylinder, Elite Silicone sleeve, motorless, 28.6 cm length, 19.1 cm insertion, Ø 3–5.1 cm

Description
The Pump Worx Max Boost Blue is a manual piston-action penis pump with a clear polycarbonate cylinder, ergonomic grip and removable Elite Silicone sleeve. Designed to encourage blood flow and temporary tissue expansion, it supports firmer, stronger and longer-lasting erections without pills or electrical motors. The motorless, in-line pump is self-contained — no hoses or external parts — and the crystal-clear tube includes an easy-to-read ruler to monitor changes in size. The pump is suitable for use in dry conditions or filled with water for a different sensation, and the quick-release button allows immediate pressure relief.
Advantages
The Pump Worx Max Boost Blue delivers reliable suction through its piston-action mechanism while remaining quiet and portable due to its motorless design. The heavy-grade polycarbonate tube provides clear visibility and measurement, and the removable premium silicone sleeve offers hygienic, comfortable contact with the skin. The device is easy to operate, requires no batteries or attachments and includes a quick-release for safe pressure removal.

Usage recommendations
Use the pump for short sessions and follow safe practice: do not over-pump, stop if you feel pain or numbness, and consult a healthcare professional if you have cardiovascular conditions, blood-clotting disorders, or implanted devices. Clean the sleeve and cylinder after each use according to the manufacturer’s instructions and store the product in a dry place.
