Developer & Manufacturer of the
"World's Only Hinged Vacuum Tube"
Hello, my name is Master E and I am the inventor of
the tubes you see above. I just wanted to give a brief
history of why and how these tube came about. I have
been vacuum pumping since 1972 and at that time you
could not purchase any tubes- you had to make them yourself.
Which I did for many years until firms like VacuTech
and others started offering quality, professionally-constructed
all pumpers do, we continually grow and have to buy
new, larger tubes to accommodate our genitalia and eventually
we all had to get two-stage tubes. The obvious problems
with two stages are exiting without rupturing yourself
and the need to continually buy new, larger ones which
cost about $140-$180 per tube. That's where I was in
1995, many sizes of straight and two-stages, hundreds
of dollars in plastic filling my pump closet.
was the highest technical level in tube design until
1995, when I developed the MONSTER TUBE. Not only is
the Monster Tube a two-pice hinged cylinder for easy
access & exit, but the shape of Monster Tube eliminates
genital distortion. You will never outgrow or get stuck
in a tube again. And the effectivness and the efficiency
in growth from Monster Tubes is unmatched in any other
vacuum tube on the market.
U.S. Patent Office agreed with my claims about the tubes'
unique ability to enlarge WITHOUT genital DISTORTION
and how quickly and easily the genitalia increase. I
was awarded a patent on the MONSTER TUBE. It is the
ONLY PATENTED,HINGED vacuum tube being offered in the
