Interior Diameter of the Bathmate.

Does anyone know what the interior diameter of the Bathmate Hercules is? I know the outside goes from about 7 5/8 inches right above where it flares to meet the bellows, to about 7 1/4 inches at the 200 mm mark. Now I know there is a bit of magnifying glass effect that goes on because it’s filled with water, but I’m pumping at a lower vacuum today, and mt dick looks so fat in the tube. So close to filling the tube girthwise. I know it’s just because it’s under vacuum, but it looks soo freakin’ cool. If it could touch the interior walls of the tube, how big would that be?

Nobody? I emailed Bathmate customer service and asked them. I measured the outside of the tube’s circumference. I tried to guess the thickness of the plastic, and it doesn’t seem to be very thick.

Measure the inner diameter and multiply by PI.

Yeah, that occurred to me, but I can’t really reach inside.

OK, I tried as best as I could to figure the interior diameter, and it seems about 2.125 (2 1/8”) inches. That makes for an interior circumference of 6 and 5/8”.

You need a vernier caliper to measure the inside accurately. Customer services should have the figure to hand; you can’t be the only person who’s ever asked!

I’m sure it is the “magnifying glass” effect that the tube full of water produces, but I looked at myself in the mirror with that Bathmate on yesterday, and my dick looked FAT. Like just about to touch the walls of the tube. It looked freakin’ awesome.

In the bathtub full of water immerse the bathmate and then look at it the tub water will cancel out the bathmate water and will give a better look!

I bet a good mathematician (not me!) could tell you the internal diameter if you know the length of the tube and the volume of water the tube holds!

Sure but going to buy a vernier caliper would be faster.

I think my 6 5/8” is really close.It’s not a straight cylinder really. Probably 6 5/8” at the base and 6 1/4” at the 200mm mark.
