Stand-alone pump gauge

>When I got home and realized there is big difference in vacuum PSI

What do you mean? The difference in inches of mercury vs. PSI? A vacuum gauge that reads in PSI will work fine, though you’ll need to adjust the numbers compared to the more common inches of Hg given here.

1 PSI = 2” Hg, so 5” Hg = 2.5 PSI. Use half the PSI as you would inches Hg.

>Sorry , I meant the vacuum tube was 2½” the flexible tube was aboaut ¼” but my dick was not feeling much in the way of pressure.

The pumping tube diameter doesn’t make much difference as long as the tube you’re sucking on is much smaller. Try using a 1/8” inside diameter suction line.

Well, some of us have funny fetishes

What I meant was it was a pressure gauge not vaccum so Im goiing to try to take it a part like petitfaun recommended.

“I haven’t tried it yet, but it may be possible to make a vaccum pump by converting a tyre inflator. Opening it up and changing the washer inside the cylinder, back to front so when it is pumped the air is sucked through the nozzle end and expelled throught the normal input end. I was going to try it out but I’ve just had to cram everything in my garage to take in some new fencing so it’s a bit difficult to find a wrench (to open up the cylinder).”

I did get a chance to try it today but met with dismal failure. Reversing the washer and metal support caused the swing of the centre rod to describe a different arc and the metal support was rubbing against the cylinder and jamming.

I also had another try at the larger home-made pumper but even making the seal against my body didn’t improve things. I think it must be related to the fact that to put the same pressure into a larger container needs more power, so is it logical to assume that making a vacuum in a larger contaianer would need more power?

I’ll leave the experts to argue the pros and cons of that!

I simply noticed that using oral sucking (this is getting disgusting!) through a flex tube for a 1¾” pump caused my dick to swell and eventually the foreskin was all puffed out, Whereas the 2½” tube had far less effect.
