Penis Pump Cylinder (2" x 9", Clear Acrylic)

This is the replacement tube for your Size Matters pump, machined from thick, crystal-clear acrylic with a 2 inch inside bore and 9 inches of usable length. It tapers toward the top so it sits closer to your natural shape, and the built-in air valve lets you pop it off the pump without losing the pressure you've built.

• Inside diameter: 2 inches. Length: 9 inches.
• Tapered top for a more comfortable, anatomical fit
• Quick-release air valve holds pressure when you disconnect the pump
• No gaskets to buy or replace
• Thick, see-through acrylic so you can watch your progress
• Works with Size Matters pumps (pump sold separately)

Materials and care: Solid clear acrylic. Rinse with warm water and a mild toy cleaner after each use, let it fully air dry, and store it out of direct sunlight so the acrylic stays clear. Skip harsh solvents, they can cloud or crack the tube.

Honest note: This is a cylinder only, not a complete kit, so you'll need a compatible Size Matters pump and hand ball or trigger to use it. A 2 inch bore fits most users comfortably, but if you're on the larger side around the base you may want to size up. Go slow with the pressure and use a little water-based lube around the base for a better seal and an easier release.

FAQ

Does this come with a pump?

No. It's the cylinder by itself. It's built to pair with Size Matters pumps, which you buy separately.

What size is it?

The bore is 2 inches across and the tube gives you 9 inches of length, tapered toward the top.

Is the shipping discreet?

Yes. It ships in plain packaging with a discreet billing descriptor, so nothing on the box or your statement spells out what's inside.
