Design for a low Hg all night pump


Design for a low Hg all night pump


I wore the vac extender suction cup (with all the air pushed out) a few months ago; this means that there was a low Hg (no more than 0.5) acting on the penis head. This was fairly comfortable and did give good head girth gains when I wore it for a week or so.

My idea is to build on this by using a presta valve, a clear plastic pipe with one end closed and one end open, and a wide silicone sleeve to seal the cylinder. The seal point will be 1 cm from the base of the penis. A bicycle handpump can draw air out of the cylinder (when air tight) decreasing the pressure. The cylinder is much smaller than the standard pump sizes and made for length gains so 25 cm long x 6 cm internal diameter. A usb electrically heated pad can be used at the penis base (just before the cylinder) to keep the blood flowing. A wear time of around 4 hours could be possible.

It is not possible to increase the vacuum Hg after detaching the hand pump, and the penis is heated throughout the process by the heated pad. The vacuum pressure is very low (no more than 0.5 with a starting Hg of 0.1). The vacuum is applied to the entire penis minus 1 cm from the base (which is where the silicone sleeve makes the seal).

Any input on this? It could work!

Bpel: 8", Bpeg: 6", Mbeg: 5.75", Meg: 5.5", Aheg: 5.25", Heg: 4.5" - 11/18/11

Bpel: 8", Bpeg: 6", Mbeg: 5.875", Meg: 5.63", Aheg: 5.38", Heg: 4.75" - 5/18/12

Bpel:+1/4", Bpeg:6", Mbeg: 5.875", Meg:+1/16", Aheg: +1/16", Heg: +1/16" - 6/18/12

Extended vacuum tends to just draw more lymph fluid into the skin and that is not going to lead to gains. What you are describing as a very low vacuum might help avoid this, but you will have to be the guinea pig on this experiment. Keep us updated on your results.

The primary goal of PE should be to make your penis as healthy as possible in both form and function. If you do that, increased size will follow.


Forgot to add that I will be wearing a silicone sleeve on the penis throughout the pressure application; this is to slow fluid build up

Never even heard of those things before. Looks like decent construction and waaay more reasonable prices than much of the PE gear on the interwebs.

Thanks Divider.

I have figured out to do exactly the same using the following equipment:

1 x cylinder (1.75 inch internal diameter to 2 inch internal diameter) with mustang press
1 x silicone penis pump sleeve off Ebay
2 x 2 inch wide silicone sleeve supplied with the vac extender 3 off the vac extender website
1 x condom

Put the condom on first, roll down to base, then put the two silicone sleeves over each other as far into the base as possible (over the condom, on top of each other and unrolled fully)
Put the silicone penis pump sleeve over the 2 inch wide silicone sleeve and then put the cylinder on the penis and make the seal with the silicone penis pump sleeve
Connect the pump press and pump to 4 Hg
Disconnect the pump press and move the cylinder such that it is resting on your chest, some air should be expunged from the cylinder
Reattach the pump press and measure the Hg, should be around 1 Hg,
Adjust the Hg value to between 0.1 Hg and 0.5 Hg
Disconnect the pump press again
Put a sports sock over the cylinder right down to the base

Finished, you can now sleep with a Hg of between 0.1 and 0.5 with a good seal, this allows the cylinder to be moved around comfortably
I have not figured out how to do attach the heated pads yet, will put a photo of the setup this evening

Why not just get an electric cycling vacuum pump and make a night routine?

Djrobins - this is primitive however is safe because once the Hg is set there is no way to accidentally increase the Hg once the hand press is disconnected. But I am interested, do you have any links for an electric cycling vacuum pump?

Search ALEAS aquarium pump on ebay, the 3W one has a regulator switch on it. Do the “15$ vacum pump” mod, by turning around the pump valves.


It worked!! I happily slept for 6 hours with the following setup

1 x 2.25 internal diameter pump connected to a mustang hand press set at 0.5 Hg
1 x penis pump silicone sleeve
1 x durex condom
1 x usb powered heating pad
1 x thick sports sock
1 x 2 inch wide silicone sleeve (supplied with the vac extender 3 pack)

Put durex condom on erect penis, put the 2 inch wide silicone sleeve on the middle of the penis, put pump with the sleeve attached onto the penis, make the vacuum seal, put the usb pad on the penis base (lightly tie on using shoe laces), pump the hand press to 4 Hg, disconnect hand press, move cylinder around a bit to ensure that the cylinder has a flexible seal (should loose a little bit of Hg), reconnect the hand press and adjust to 0.5 Hg. Put the thick sports sock over the entire cylinder and silicone sleeve.
Put the cylinder over your right leg at 45 degrees to the leg (can tie around the leg using a strap if necessary or if you move a lot whilst sleeping)
The setup worked well the glans were a little purple but it worked well.


The setup described above works better with the cylinder at 90 degrees to the body (straight up) this means that higher Hg can be used. The cylinder is pressed lightly under it’s own weight against your pubic bone and with the thick silicone sleeve this stops leaks from happening. Same equipment as above with additional
4 x 4 cm shoelace cuts superglued in closed loops at 90 degrees apart at the top of the cylinder
4 x 4 cm shoelace cuts sewn in closed loops at 90 degrees to each other around your pajamas trousers
4 x 20 cm shoelace cuts to secure each cylinder loop to your trouser loop

This setup stabilises the cylinder and stops it from changing position, I slept happily for 6 hours with this on with no vacuum leak at 0.2 hg, woke up and there was no discolouration although the penis was slightly hard when erect (effect of pumping)

Will have a break for 4 days (no PE) and then try the improved night time routine then

Sorry to get off topic.

I like what you’re doing though Jack1015. Keep us updated please.

Proof that the all night pump did increase fatigue (not absolute) is:
I did my standard pump set of 15,15, 10 x 4 Hg (minute x hg set) with 3 minute breaks, then did 7 hours at 0.5 hg sleeping on 15/01/2012, normally I recover within 48 hours but still not recovered (18/01/2012) although had a near erect flaccid whilst sleeping on 17/01/2012, where I would normally have full erections (sleeping) so EQ has taken longer to recover. NBPEL reduced from 173 mm to 163 mm immediately after the night set but has recovered to 173 mm now.
Will post measurements tomorrow but looks good so far, would recommend no more than 0.3 Hg as it is considerably more effective than I thought

Awesome experiment. Keep logging more this could be good.
