Most hookahs have an air release valve that helps to clear smoke from the vase. These valves typically have a small ball bearing inside that is responsible for opening and closing the valve. Hookah ball bearings are specifically designed for this purpose and are generally made from stainless steel or another durable material. While hookah ball bearings are not required for every hookah, they can be helpful in ensuring that smoke is properly cleared from the vase. In addition, they can help to prolong the life of the air release valve by preventing it from being damaged by debris. Whether you're looking to improve the performance of your hookah or simply want to replace a worn-out part, hookah ball bearings are an essential component.
