This glass joint adapter converts a 14mm male connection to an 18mm male fitting, letting customers pair accessories and water pipes that would otherwise be incompatible. Made from durable borosilicate glass, it's a small piece that solves a common, everyday problem.
Joint adapters are one of the easiest upsells in the shop — nearly every customer who mixes and matches glass eventually needs one, and keeping a full range of size conversions on hand means shops rarely have to turn away a sale.
