Stop your bottle falling over - This rubber boot simply pushes on to the the bottom of your cylinder and gives a flat base to help prevent the bottle from falling over.

Protect the base of your cylinders - The flat bottoms allow the cylinders to stand upright and are vented with ribs and drain holes to allow water to drain away to help prevent corrosion.

Designed fit perfectly over the bottom of your steel diving cylinder, providing superb impact protection and improved stability.

Made from a high quality rubber compound.
