Standard Design Penis Enhancer Cylinder

Standard Design Cylinder a.k.a. Classic Design: BostonPump’s Standard Design penis vacuum cylinder is the oldest and one of the most popular cylinder on our site. This design has a classic upward flared neck with built in cock-ring. The Standard Design penis suction cylinder is among the strongest penis enlarger cylinder on our catalog. All BostonPump.com cylinders are plug and pump ready, equipped with state-of-the-art quick-disconnect couplings and growth indicator.  The built in cock-ring is designed internally and is an integral part of the design. Because of the cock-ring, the cylinder stays nice and tight  without sucking in much of your scrotum or squeezing the base of your groin. By having a built-in cock ring, the opening diameter of the Standard designed cylinders are somewhat smaller than the other BostonPump penis suction cylinders. It is for the same reason that the standard cylinders are capable of more intensive suction than the other models without this feature. The reduction in opening diameter is about ¼” to 1/2 " smaller than the actual size. As an example, if you choose a size 2” Standard Design cylinder, the opening size is almost 1 3/4”. Please choose the size of the cylinder based on its actual size and not the base.

-Pros: Capable of high suction, Suitable for Hydro-penis pumping, Built-in cock-ring.

-Cons: Requires full shaving for best suction.
