FAQs About Human Grade

What joint size do Human Grade bongs and accessories use?
Most Human Grade water pipes, ash catchers, and downstems use standard 14mm female or male joints. This makes it easy to swap out bowls, add a quartz banger, or attach an ash catcher without needing awkward sizing adapters.

How do I measure my water pipe for a replacement Human Grade downstem?
Measure from the top edge of the ground glass joint down to the end of the tube, stopping about half an inch above the bottom of your water chamber. Human Grade color downstems even include a printed ruler on the packaging so you can double-check the exact length before opening it.

Are Human Grade aluminum grinders durable?
Yes. Human Grade 4-piece aluminum grinders feature sharp, CNC-machined teeth, smooth threading, and integrated pollen screens. They shred herb cleanly without flaking metal or jamming, giving you a consistent grind every time.
