Signature Features of Kovacs Glass Gridded Stemline Perc Bongs

The gridded stemline percolator is a hallmark of Kovacs' gn. Built directly into the fixed stem, this type of diffusion offers smooth, low-drag filtration by breaking up smoke or vapor into fine bubbles. The result? A clean, flavorful hit with less harshness and more control. Whether you prefer flower or hash, this scientific-style bong is ideal for daily use and trusted by experienced smokers.

Spinner Carb Caps

Kovacs Glass also crafts high-performance spinner carb caps, designed to optimize airflow and promote vortex action in your banger. When paired with terp pearls, these caps spin air evenly over your dabs, maximizing surface area and delivering better vaporization of concentrates at lower temperatures—perfect for flavor-focused hash smokers.

Scientific Craftsmanship

Each piece is made from high-quality borosilicate glass and reflects a true glass artisan's care, experience, and technical skill. The focus is always on clean execution and precise function, making Kovacs a go-to brand for those who value reliability in every session.
