This EHLE Reducing Diffuser will allow you to transform your 29.2 joint size bong into a 18.8 joint size. The male joint is 29.2, but the female joint is 18.8 to take 18.8 size bowls only.
EHLE's replacement parts are made with precision joints and EHLE are rightly proud of them. Technically speaking, these EHLE puncture-hole diffusers leave nothing to be desired. The joint walls are twice as thick in comparison to common industrial joints. The ringless, rounded rims of EHLE joints on both pipes and parts will pardon one or two ungentle knocks.
Flame-polished EHLE logos on these reducing diffusers are a classy touch and their perfect functionality improves the flavor and taste of your smoke.
