Packed tube pump for length gains

Hello friends

I´ve been doing my maths and if I am not wrong, pumping in a 1.75” inch tube, if the tube is packed, the pressure inside, translated to longitudinal pull, would be as follows:
5 inHg= 2.4 Kg or 5.3 pounds
7.5 inHg= 3.6 kg or 8 pounds
10 inHg= 4.8 kg or 10.6 pounds
12.5 inHg= 6 kg or or 13.2 pounds
15 inHg= 7.2 kg or 16 pounds
30 inHg= 14.5kg or 32 pounds

If there´s a correlation to the effects of hanging, would be like that.
However as the corpora cavernosa is full, the tension is applied somewhat differently, but this could be positive as it also creates the conditions of the erection and expansion.

But how effective is it to gain length?
Are there some success experiences by some veteran gaining length in a pump tube here?

thanks

I attribute all of my length gains to pumping.

could you outline the procedure you used?

Pumping five days a week. Adding time over months/years. The big part was wrapping the cylinder with a heating pad.

how long the sessions?
how much pressure?

Just one word of caution. Once you pack the tube, all of the vacuum force is now focused on the glans and with increased vacuum pressure and or time, you become very susceptible to getting blisters on the glans and those are a real bitch.

At what pressure you would say blister risk is a real threat?

I´ve only experienced blisters using those silicone caps with vacuum extenders….

It kind of a pressure/time factor. So after packing staying at pressure of 8 or above for 15 minutes or longer could get you into this problem, but these only estimates. Also, it seems once you get a blister, it seems to have a lasting effect on future occurrences but this is hard to quantify.

I had a superficial blister that healed in 1 week and left no sequels, but i had also a deep blister that healed in 2 weeks and left a dent that can turn black under some pressure.

I think if a thicker layer of skin is detached from the underlayers, that is, if the fluid bubble is lodged in deeper level, the sequels can be long lasting.

Is it necessary to stay at 8 ? I´d say 6-10 feels high pressure but i´ve only had a handful of sessions.

It is impossible to put exact numbers on this. It’s just important to know that after packing, the glans is more prone to getting blisters.

For me, I never pack anymore. I always pump with a tube ¼” larger then one I can pack.

Why would pump with packed tube be different than hanging?
if it is applying the suction pressure in the longitudinal axis only.

Wouldnt pump equal hanging if pressure in the chamber exert the same pull in long axis as you would while hanging?
only difference is the penis chambers are full, which is indeed relevant in as much as the septum will receive less pull, and some will be distributed more in the outer tunica but anyway the chambers have to adapt to some volumetric increase too, not just longitudinal, in order to achieve size gain…

Some people have experienced a lot of length gain using exclusively a pump but seems like not many.
Why is this? why studies dont back pumping as capable of permanent gains?

so

Excellent approach!

Cylinder’s on the way I got a 9x2 already, but now noticing how the dick stretches once the tube is packed girth wise I had to go back to this tread and another one similar to study this(had read this a while back) and order a 9x1.75 for lenght, I’m able to pack the 9x2 by the 3rd set currently but it’s when the dick gets a bit of limb fluid, so I’ll switch in between tubes once it gets here I gotta come up with a routine, any ideas are welcomed!

Wait you have a dent that turns black under pressure now?…

Have you gotten this looked at?…

I think you’ve got some good points as far as how the vacuum affects the penis but I’m quite certain that pumping is very different from hanging in that the stretch is focused length wise with hanging and also affects the ligaments where as pumping does not. Also pumping I believe causes expansion outward from within the penis due to the vacuum where as hanging only creates tension through gravity and there’s no expansion outward.

I’m no professional but from what I’ve read
