18.8 to 14.5mm Chillums
In this section you will find our range of different chillums and couplings with 14.5>18.8 ground joints. These inserts have a male 18.8 core cut to the bong and a female 14.5 cut for the use of bowls and bong accessories. We offer these chillums with or without a diffuser end piece as inline chillums, where the outer and inner ground glass joints have been processed into each other to reduce the overall length of the glass insert.
