The glass top on a Puffco® Peak® isn't just a water chamber, it's what shapes every draw. Swap it and you change how smooth, cool and flavorful your hits are. But dry, dome perc, swiss perc, recycler, incycler, what's the difference? This guide breaks down the main Puffco Peak glass styles so you can pick the replacement top that fits how you like to dab. (These are aftermarket, Puffco-compatible pieces, more on that below.)
Why the glass style matters
On an e-rig like the Peak, the atomizer heats your concentrate and the vapor travels up through the glass before you inhale. The percolator (or lack of one) in that glass decides how much the vapor is cooled and filtered. More percolation means smoother, cooler hits; simpler glass means more flavor-forward, less-diffused draws. It's the same principle as a bong percolator, just sized for an e-rig.
Dry (no perc)
A dry top uses no water at all. Vapor passes straight through, giving you the most direct, flavor-forward hit with zero drag. It's the simplest option, nothing to fill or spill, and it's popular with flavor chasers and anyone who wants the lowest-maintenance setup.
- Best for: maximum flavor, simplicity, no water.
- Trade-off: warmer, less filtered than water styles.
Dome perc
The dome perc is the everyday all-rounder. A single dome-style percolator diffuses the vapor through water for a noticeably smoother hit than dry, without much added drag. It's the closest to Puffco's classic feel and a safe pick if you're not sure where to start.
- Best for: balanced smoothness and easy use.
- Trade-off: less cooling than a recycler or swiss.
Swiss perc
A swiss perc has "holes" through the glass body (like swiss cheese) that force vapor around and through for extra diffusion. It cools well and looks striking. Many swiss designs pair with a recycler function for even smoother pulls.
- Best for: heavy diffusion and a standout look.
- Trade-off: a bit more to clean around the holes.
Recycler
Recyclers continuously loop the water through two chambers, so the vapor is cooled again and again. The payoff is some of the smoothest, coolest hits you can get in this form factor, plus a mesmerizing spin. Great for bigger draws and low-temp dabbing.
- Best for: the smoothest, coolest hits.
- Trade-off: pricier, more glass to clean.
Incycler
An incycler is a recycler with the loop built inside the main chamber rather than through an external arm. You get the same constant-recirculation smoothness in a more compact, protected design, fewer external tubes to bump.
- Best for: recycler smoothness in a tidier shape.
- Trade-off: premium option.

Which glass should you choose?
- Want pure flavor and no fuss? Go dry.
- Want a smooth, classic all-rounder? Dome perc.
- Want maximum cooling? Recycler or incycler.
- Want heavy diffusion with style? Swiss perc.
Whichever you pick, dab low for the best flavor, the same rule applies to e-rigs as traditional rigs; see low-temp vs high-temp dabs. New to concentrates entirely? Start with our beginner's guide to dab rigs.
Will it fit your Peak?
Check your model before buying. The original Peak and Peak Pro share the same glass base, so most tops fit both. The New Peak (2024) uses a different attachment system and needs glass made for it. Every listing in our collection states exactly which device it fits, so match it to your Peak and you're set.

Frequently asked questions
What are the different Puffco Peak glass styles?
The main styles are dry (no water), dome perc, swiss perc, recycler and incycler. They range from the most flavor-forward (dry) to the smoothest and coolest (recycler and incycler), with dome and swiss percs in between.
Which Puffco Peak glass gives the smoothest hits?
Recycler and incycler tops give the smoothest, coolest hits because they continuously loop the water to cool the vapor multiple times. A dome or swiss perc is smoother than dry but not quite as cool as a recycler.
What's the difference between a recycler and an incycler?
Both constantly recirculate water for cooling. A recycler routes the loop through an external arm, while an incycler builds the loop inside the main chamber, giving the same smoothness in a more compact, protected shape.
Does Puffco Peak glass fit the Peak Pro?
Usually yes, the original Peak and Peak Pro share the same glass base and are cross-compatible. The New Peak (2024) uses a different system and needs glass made specifically for it, so always check the listing for your exact model.
Is a dry top or a perc top better for a Puffco Peak?
It depends on your priority. A dry top delivers the most flavor with no water and no fuss; a perc top (dome, swiss, recycler, incycler) cools and smooths the vapor. Flavor chasers lean dry; smoothness seekers pick a perc.
