An adapter makes your smoking paraphernalia more practical and versatile. By changing the socket size or turning a female into a male (or vice versa) you can make your bong compatible with different kinds of bowls and nails, and allow you to connect pre-coolers and other accessories for a better/different smoking experience. An adapter can also extend the distance between the banger and your bong making it easier to warm up. Here you can find adapters in different designs, for different socket sizes and uses.
