Check chamber fit before pumping
The 8.8-inch length and 2.3-inch diameter are the chamber’s internal measurements. They are not target body measurements, enlargement promises, or proof that the base sleeve will fit every user. Compare both erect length and girth with the chamber dimensions and leave clearance rather than trying to overcome a tight fit with more vacuum. The 0.8-inch sleeve opening is measured unstretched and does not define a guaranteed fit range.
Before first use, inspect the cylinder, sleeve, tubing, pull handle, connections, and release valve. Confirm that the valve releases pressure while the device is not sealed against the body. Do not use a cracked cylinder, torn or hardened sleeve, loose tube, jammed handle, blocked valve, or damaged pump body.
Use pressure gradually
Read and follow the directions supplied with the pump. Keep the release valve within easy reach, create a comfortable seal, and use slow, controlled handle strokes. Use only the minimum vacuum needed for the intended temporary effect. Pause to check skin color, temperature, sensation, comfort, and swelling. Never try to overcome leakage or poor fit by pumping harder or faster.
- Release pressure and remove the pump immediately for pain, marked discomfort, numbness, coldness, unusual blue or purple color, pinpoint red spots, bruising, bleeding, or excessive swelling.
- Use only while awake, unimpaired, and able to operate the release valve promptly. Do not sleep with the pump in place or use it while impaired by alcohol or drugs.
- Consult a qualified clinician before use if you take blood-thinning medication, have sickle cell disease or another bleeding or clotting disorder, have reduced genital sensation, or have another condition that could make vacuum use unsafe.
- If you are using a pump for erectile-dysfunction symptoms, ask a qualified clinician about an appropriate device and instructions. This retail product page does not establish medical suitability.
Vacuum can create a temporary fuller appearance by drawing blood into the penis. It does not permanently enlarge the penis, cure erectile dysfunction, or guarantee a particular result. Excessive pressure, overly long sessions, or repeated aggressive use can cause bruising, swelling, pain, or injury.
Release, cleaning, and storage
To stop, use the release valve and wait until the vacuum has fully dissipated before sliding the pump away. Never pull the cylinder against an active vacuum. If pressure does not release promptly, stop using the product.
Follow the enclosed cleaning directions for the exact unit you receive. Clean body-contact surfaces after use with a method compatible with SAN plastic and silicone, rinse away residue when the instructions call for rinsing, and dry every part completely before reassembly or storage. Keep the pull-handle pump and tubing dry unless the supplied directions specifically allow water exposure. Store the pump uncompressed, away from direct sunlight, extreme heat, sharp objects, and materials that can deform the sleeve.
