SiliStretcher All Day Penis Vacuum Stretcher and Weight Hanger



With over 15 years of research and development, MOS is proud to bring you our stealth SiliStretcher for eight-way all day penis stretching and weight hanging to permanently increase penis size.

The SiliStretcher is the first ever robust piston vacuum system for all day penis stretching (ADS) and penis weight hanging to comfortably and effectively add length and girth to your penis.

The SiliStretcher effortlessly stretches your penis tissue and ligs and then allows you to heal in that extended state to gain permanent penis length and girth as tissue heals. The SiliStretcher is self contained and requires no external pumps or attachments. 

Dubbed as "The Most Comfortable ADS in the World", the SiliStretcher can be comfortably worn all day for many hours as an eight way all day stretcher in stealth mode under your clothes while you are at work or out running around.  When you are at home, you can use the SiliStretcher for your weight hanging sessions.

The piston vacuum and SiliSleev/SiliCap combination provides the ultimate in comfort with no blistering such as associated with standard hangers and ADS systems.

The SiliStretcher is the only all day stretcher that offers eight stretching positions to work the penis ligaments. The included adjustable ADS belt gives you left and right side waist stretching and downward left and right leg stretching.

The optional SiliStrap gives you upward left, right, center stretching and downward between the cheeks stretching for intense penis ligament stretching.

We also include MOSGrip to maximize your penis stretching sessions. MOSGrip eliminates natural oils from your skin and creates a tack for maximum grip.

The SiliStretcher is used for flaccid stretching and hanging.

The national average flaccid penis girth is 3.66” (93mm) circumference which equates to a 1.1" (28mm) diameter.

The medium size SiliStretcher internal diameter is 1.5" (38mm) and will work for most men up to a 6" (152mm) flaccid girth. If you have an abnormally small or abnormally large circumference flaccid girth, please contact us for an alternate size SIliStretcher.

To get the proper circumference measurement for sizing your SiliStretcher,
use a measuring tape and wrap it around 7the thickest part of your glans in flaccid state.

How to use

  1. Apply MOSGrip powder to your penis
  2. Apply the SiliCap to the head of your penis to prevent fluid retention, blistering, bruising and reduce sensitivity.
  3. Roll the SiliSleev back over the SiliStretcher
  4. Put the head of your penis into the SiliStretcher
  5. Unroll the SiliSleeve over the shaft of your penis
  6. Turn the SiliStretcher vacuum piston knob a full twist counter-clockwise. One full turn of the vacuum piston knob is 10 in.-Hg vacuum. Your penis will be safely and pulled and secured into the SiliStretcher.
  7. Attach to the ADS belt or hanger.
  8. Adjust tension or weight to begin session.

To release vacuum, give the SiliStretcher vacuum piston knob a couple twists clockwise.

For the most effective sessions with the SiliStretchers and SiliSleevs, follow this guide below.

Make sure your entire penis is shaved clean of hairs
Hairs will create loss of suction with SiliSleevs and the SiliStretcher .

Make sure your penis is clean, dry and free of oil
If you put lotion on your skin, this will cause loss of grip . Your skin also has a natural oil that can cause loss of grip. Sweat causes loss of grip. We strongly recommend cleaning and drying your penis then using MOSGrip to remove all the natural oils of your skin and create a tack for maximum grip. MOSGrip also helps eliminate sweat under the SIliSleev .

Make sure your SiliSleevs are clean, dried and powdered with MOSGrip
Dirty oily SiliSleevs with pubic hairs in them will cause loss of suction/vacuum /grip . You want to clean your SiliSleevs before each use

Make sure you do not have a pin hole in your SiliSleev from excessive use
Pinholes are easiest to find if you blow up the SiliSleev with a little air from your mouth. Don't blow them up In a big balloon. Pin holes are like a slow leak in a tire.
