The Human Grade Color Downstem is a 14mm replacement downstem available in three sizes and nine full-color options — giving you the exact fit and the exact look you want for your water pipe. Whether you're replacing a broken downstem, upgrading from a stock clear one, or matching a color theme across your setup, Human Grade makes it easy to find the right piece.
Not sure which size you need? Each package includes a printed ruler directly on the packaging so you can measure your existing downstem and joint size before you even open the box — a thoughtful detail that takes the guesswork out of replacement shopping. Choose from 4-inch, 4.5-inch, or 5-inch lengths in colors ranging from Amber and Pink to Lake Green and Lavender, and drop it into any bong or water pipe with a 14mm joint.
Features
- Three Size Options — Available in 4", 4.5", and 5" lengths to fit a wide range of bongs and water pipes. Select the length that matches your current downstem for a guaranteed drop-in replacement.
- Nine Full-Color Options — Choose from Amber, Green, Lake Green, Lavender, Light Blue, Matrix Green, Pink, Smoke, or Yellow. Color runs through the glass — not painted on — so it won't chip, peel, or fade over time.
- Universal 14mm Fit — Standard 14mm joint size that drops into any bong, water pipe, or bubbler with a 14mm female connection. No adapters or modifications needed.
- Optimal Airflow & Filtration — Slitted diffusion at the submerged end breaks smoke into fine bubbles, increasing water contact for smoother, cooler, and better-filtered hits.
- Printed Ruler on Packaging — A measurement guide printed directly on the box lets you measure your current downstem and joint size to confirm the right replacement — before you open the package.
- Durable Glass Construction — Built to withstand regular insertion, removal, and cleaning without cracking or degrading.

How to Measure Your Downstem
Step 1: Remove your current downstem from your bong.
Step 2: Measure from the bottom of the frosted ground joint (where it seats into the bong) to the very bottom tip of the downstem. Do not include the joint section that sits above the opening.
Step 3: Match your measurement to the closest available size — 4", 4.5", or 5".
No downstem to measure? Use the printed ruler on the Human Grade packaging, or insert a pencil into the joint of your bong until it touches the bottom of the base, mark the depth at the joint opening, and measure that length.

Why Choose the Human Grade Color Downstem?
Downstems break. It's one of the most commonly replaced parts on any bong — they're thin, they're constantly being pulled in and out, and a single clumsy moment over a hard countertop can end one instantly. When yours breaks, you want a replacement that fits right, ships fast, and doesn't force you to settle for generic clear glass.
Human Grade gives you nine color options and three size options, which means you're not compromising on fit or aesthetics. Match your downstem to your bowl, your ash catcher, or the accent color on your rig — or go with a contrasting pop of color that makes the piece feel brand new. The color runs through the glass itself, so it won't fade, chip, or wash off no matter how many times you clean it.
The printed ruler on the packaging is a small detail that solves one of the biggest headaches in downstem shopping — ordering the wrong size. Measure your old one against the ruler, confirm the length, and you know before you open the package that you've got the right fit. If your original broke and you have nothing to measure, the pencil trick works just as well.
Whether it's an emergency replacement or a planned style upgrade, the Human Grade Color Downstem delivers the right size, the right color, and a hassle-free fit for any 14mm water pipe on the market.
