For men using the Osbon ErecAid Esteem Vacuum Therapy System, the Standard Tension Ring is the everyday clinical accessory designed to maintain a firm erection once achieved — safely, comfortably, and reliably.
Patented and medically engineered in the US, this is a purpose-built clinical ring, not a generic constriction device. It is designed specifically to work with the Osbon ErecAid system, applying the correct level of pressure to restrict venous outflow and maintain erection firmness during intimacy.
How it works
Once an erection is achieved using the vacuum therapy system, the Standard Tension Ring is applied at the base of the penis. It restricts the natural outflow of blood from the erectile tissue, maintaining engorgement and firmness for the duration of intimacy.
The ring features unique pressure-point bumps, expertly positioned to press against the veins that sustain an erection — applying targeted compression where it is clinically needed. The urethral 'U' notch allows ejaculation to occur safely while the ring is worn, making it suitable for use both with the vacuum system and independently during intimacy.
Seven combination options
The Osbon tension rings are designed to be used individually or in combination. The full User Guide details seven possible combinations to accommodate a wide range of penile girths and desired results — giving you precise, personalised control over the level of compression that works best for you.
