A stem kit is the quickest way to bring an old bong back to life — one purchase gets you a matched stem, cone piece and collar that all work together straight out of the box. No guessing sizes, no mixing and matching parts that don’t quite fit. We stock bong stem kits from Waterfall and The Bong Shop, All delivered in discreet plain packaging anywhere in Australia.
Shop Bong Stem Kits by Fitting Type
Two fitting types across this range — getting the right one is the most important step:
-
Standard stem kits — three options from Waterfall including Slip-In, Pop-In and Screw-In cone configurations. Standard fitting suits bongs with a standard grommet hole. The Standard Anodised Brass Slip-In Cone & Collar Stem Kit, available in multiple lengths from 8cm upwards.
-
Bonza stem kits — four options from The Bong Shop including Slip-In, Pop-In and Screw-In cone configurations. Bonza fitting suits bongs with a bonza grommet hole — the most common fitting on Australian acrylic and glass bongs. Multiple length options available. All bonza kits are rated 5.0 stars.
Not sure whether you need standard or bonza? Check how your current stem connects to the bong — if it’s held in place by a rubber grommet on the side of the bong, it’s almost certainly a bonza fitting.
