This 16 inch TAG water pipe runs two full percolation stages built around a Super Slit gridded inline. The lower inline perc splits the draw across a long row of fine gridded slits, dropping incoming air into a dense column of small bubbles right at the base. That column then feeds an inverted showerhead (INV4) that diffuses a second time and spreads contact across the water's surface, so every pull is cooled and softened twice before it reaches the neck. The gridded slits give heavy diffusion with manageable drag; the extra stage adds a little more resistance in exchange for a noticeably smoother draw.

The tube is made from 50MM diameter borosilicate with 5MM walls, solid heavy-wall glass that stands up to daily handling. The 18MM female joint runs a fixed diffuser stem and accepts an 18MM male accessory. It ships with a matching glass slide (female joint, so it takes a male accessory of its own size). The sandblasted logo is etched permanently and will not fade with cleaning.

This is a made-to-order (CMTO) build, so it is not ready to ship and is cut to spec on order. Expect roughly an inch of height variance. Avoid thermal shock: no boiling or freezing water, and let the glass reach room temperature before any temperature change.
