SizeMatters Penis Pump Cylinder 1.75 X 9

The Size Matters Penis Pump Cylinder in 1.75 x 9 inches is a replacement or upgrade penis pump cylinder made from crystal-clear acrylic. The 1.75-inch diameter is the smaller of the three Size Matters widths, so it suits guys who find a standard 2-inch tube too roomy. It's sold on its own, without a pump, to pair with your existing Size Matters set-up.

Choosing the right diameter

Fit matters more than anything with a pump. A cylinder that's too wide pulls skin and the scrotum in at the base and loses seal; one that's too narrow feels tight and uncomfortable. Size Matters says most men need the 2-inch cylinder, recommends the 1.75 inch if you're on the smaller side, and the 2.25 inch if you're above average. Measure your girth when aroused and divide by about 3.14 to estimate diameter; you want a little room around the shaft, but not much.

How it's made

Each cylinder is hand-made from thick, clear acrylic, so you can see exactly what's happening while you pump. The tube tapers toward the top to follow the natural shape of the penis. Size Matters says no gaskets are required. A built-in air valve lets you disconnect the hose from the pump while keeping the vacuum inside the cylinder, so you can set the pump aside and keep the pressure without holding it.

Using it comfortably

Trim or shave the base area for a better seal, and apply a little water-based lube around the opening. Place the cylinder flat against your body, pump slowly and stop well before anything feels painful. Short sessions of 10 to 15 minutes are plenty. Release the valve to let air in before you pull the cylinder away. Never pump to the point of discomfort, numbness or colour change.

Cleaning

Wash the cylinder in warm, soapy water, rinse and let it dry with the valve open. Avoid alcohol and harsh solvents, which can cloud acrylic.
