Monster Tubes Pumping Cylinders are now at The Pumping Shop!
This is the Monster Tube Jr. (we also have the Monster Tube)
These highly desirable Penis Pump Cylinders have been around the pumping community for over 25 years and have proven their worth.
Be the envy of the block with this monster of all pumping tubes. It has a bolted steel hinge on one side of the tube and 3 holes spaced around the edge to place a screw and nut to secure and close/open it.
