Give your glass a flexible upgrade with these silicone downstems, built to keep bubbles cruising even if you knock your piece off the coffee table. The 14mm male bowl joint slides into a sturdy 18mm female bong joint, while the slitted diffuser at the tip chops smoke into tiny, flavorful bubbles. Made from heat-resistant, BPA-free silicone, each stem bends instead of breaks and pops out for a lightning-fast rinse. Four length options—2.25", 3", 3.75", and 4.75"—let you dial in the perfect fit for everything from travel rigs to tall tubes.
