Penis Vacuum Pumping Guide

Looking for advice on penis vacuum pumping? This guide is designed to give you advice and information on safe cock pumping. The information also applies to clitoral, nipple and rosebud pumping. Please note that you should not insert any of the cylinders into the body except for the rosebud cylinder (and even then ONLY THE PROBE). You should never sit ONTO the cylinder.

Getting Started

Connect your cylinder to a vacuum pump using the push-fit mechanism. We strongly recommend only using a pump with a pressure gauge and trigger vacuum release. Sit securely, in a safe and secure, private place. Using a water based lubricant, lubricate the area to be pumped. This will also help keep a seal. J-Lube works well and will not rot rubber based products. Start pumping slowly; there should be a gentle tugging feeling. If there is any pain or discomfort, you should reduce the vacuum and STOP if it continues. Release the vacuum often, especially for first time usage. Little and often is the key. To release the vacuum, use the release on the pump. Removal of the vacuum fitting is not recommended or necessary to release the vacuum. DO NOT exceed a static vacuum greater than 6 inch Hg / 15cm Hg / 0.2 bar. A vacuum up to 10 inch ( 25 cm) Hg is acceptable only where the vacuum is continuously cycled slowly between 10 inch and 4 inch.


Apply only the minimum amount of vacuum necessary to achieve an erection; excessive vacuum pressure may bruise or injure the penis. The circulatory system and body tissue can easily be traumatised by exceeding the vacuum levels mentioned above either momentarily, or exceeding a lower level for appreciable periods. This may happen even with breaks and massage. Repeated damage can result in permanent erectile dysfunction and tissue fibrosis. Use of a vacuum pump may aggravate existing conditions such as Peyronie’s disease (the formation of hardened tissue in the penis that causes pain, curvature, and distortion, usually during erection); Priapism (persistent, usually painful erection of the penis as a consequence of disease and not related to sexual arousal); and urethral strictures (urethral stricture is an area of hardened tissue, which narrows the urethra sometimes making it difficult to urinate. If you have either of these conditions, please discuss with your doctor prior to use.


    • If there is any pain or discomfort, you should reduce the vacuum. and STOP if it continues.
    • If flesh goes purple or blue, cold and numb, STOP immediately and massage. You have been pumping too long or at too high a vacuum. Do not restart until circulation has been fully restored
    • DO NOT use with a cock ring or other device designed to constrict blood flow to the penis and scrotum.
    • Never use a cylinder if there is anything more than just cosmetic damage.
    • Use only water-based lubricants. DO NOT use petroleum based lubricants such as Vaseline which seal the skin. Pumping with such lubricants may cause blisters of lymphatic fluid or air from body tissue which will take time to heal, re-occur more easily and with greater frequency, and may become infected.
    • DO NOT use whilst driving.
    • DO NOT use under the influence of alcohol or drugs, as this may impair your judgment and increase the risk of injury to the penis.
      Using cylinders in warm water can be a great help and add to the fun at bath time, but DO NOT use an electrically powered vacuum pump in or near water.
    • DO NOT use if you have sickle cell disease, diabetes, a history of prolonged erections, or are taking large quantities of aspirin or other blood thinners. These conditions increase the risk of bruising and haematoma.
    • Misuse of the vacuum pump could injure the penis
    • Discontinue use and consult a doctor if any complications occur.
    • As with all sex toys, cylinders should not be shared for reasons of safer sex.


Delayed Diagnosis of Other Conditions

If you have symptoms of erectile dysfunction, i.e., inability to achieve an erection that is sufficient for sexual intercourse, consult your doctor prior to using this device to avoid a potentially harmful delay in diagnosing any of the most common causes of this condition, such as diabetes, multiple sclerosis, cirrhosis of the liver, chronic renal failure, or alcoholism.

Use with Impaired Pain Perception

DO NOT use the device if you have decreased sensation of pain in the area of the penis.

Use with Decreased Hand Strength

DO NOT use the device if you have decreased hand strength because this may make removal of the device difficult.

Cleaning Instructions

Always wash immediately after use. Warm soapy water and washing up liquid are sufficient. DO NOT wash in the dish washer, it degrades the acrylic tube, which can cause premature failure of the seals.

Petroleum and silicone based products, glycerine and cling film will also damage the cast acrylic causing a crazed or opaque look. Do not store with rubber or silicone items, including clothing, dildos, etc

Troubleshooting Guide


Unable to connect pump to cylinder

Cylinder connector locked; incompatible pump being used. Slide metal mechanism across and re-try; change pump type or connector. Thickwall cylinders are compatible with most quality brands.

No erection

No vacuum because of air leak caused by poor seal. Use more lubricant; apply firm pressure to body; trim pubic hair; check device for air leaks. Problem is most often associated with inexperience; it resolves as you become more adept at using the device.

Partial erection

Incorrect cylinder size; not enough practice sessions. Correct sizing; more practice using device. Problem most often improves with continued use of device.

Pulling the skin of the scrotum

Lubricant on scrotum; improper pumping technique; Cylinder too large; inexperience with system. Remove lubricant from scrotum; use the modified pumping technique continue with practice sessions; angle cylinder downward during pumping. Problem may disappear as you become more adept at using the device.

Rapid loss of erection (in less than 5 minutes)

Vacuum lost because of air leak from faulty equipment, , poor seal, inadequate lubrication, or excessive pubic hair. Problem most often improves with continued use of device. See No Erection

Discomfort or pain: during pumping

Too rapid pumping; pulling of scrotal tissue. Slower pumping; continue to use device only once discomfort stopped. Problem usually resolves as you become more adept at using the device.

Discomfort or pain: during intercourse

Inadequate lubrication; pressure on a sensitive area. More lubrication; position changes.

Discomfort or pain; during ejaculation

Long period of abstinence; infection or inflammation of the prostate gland. Consult your doctor if this continues. Problem usually resolves as you become more adept at using the device.

Redness, irritation or bruising

]Too rapid pumping; over Pumping. Slower pumping; fewer pumps. Consult your doctor if this problem persists.

Penis feels cold (to you or your partner)

  • Constriction of blood flow to the penis.
  • If manageable, apply the device after you have a partial erection.
  • Consult your doctor if this problem persists.

Penis pivots on its base

Constriction of blood flow to the penis; lubrication. Stop pumping and massage to get blood flowing; wash off lubricant or use warm lubricant before use. Consult your doctor if this problem persists.
