7" Swiss Hole Klein Recycler Glass Attachment for Puffco Peak & Peak Pro | Croia Glass

The Croia Glass 7" Swiss Hole Klein Recycler is a replacement glass top for the Puffco Peak and Peak Pro that turns a standard e-rig into a piece of scientific glass. Vapor enters a compact diffusion chamber at the base, then rises into a rounded Swiss hole chamber, where circular openings cut through the glass add extra surfaces for the water to move around. From there, an external Klein-style return loop carries water back down so it keeps circulating while you pull. The all-clear borosilicate build puts every curve on display, and the straight 7 inch neck with a flared mouthpiece gives you a comfortable reach above the device.

Recyclers reward a little setup. Add water a bit at a time and take a few test pulls with the glass off the base until you see it cycle through the return loop without splashing toward the mouthpiece. The trade-off for that extra filtration is upkeep, since the Swiss holes and return tube give residue more places to settle, so plan on regular soaks in isopropyl alcohol. The taller glass also sits a little top-heavy on the Peak, so set it on a flat, stable surface. Browse all of our Puffco Peak glass attachments, or see more from the Croia Glass collection.

If you want your Peak to look as technical as it performs, this recycler is an easy pick. It is a standout for anyone who appreciates detailed glasswork.
