Glass Z-core - 19/22

Glass Z-core designed for the Lamart Tetra / Tubo, RBT Milaana / Splinter and other 19mm glass joint devices.

An original Zasquatch design that provides optimal airflow, flavor, and cooling via borosilicate glass balls.

Z-designed and fabricated titanium ball retention screen system provides an innovative way to keep the balls secured. The side with the thinner walls provides access to the 3/8” standard pipe screen for easy replacement or cleaning. When installing the device, the side with the thinner walls should be facing the balls.

The default configuration includes a high volume of balls with a basket screen at the end of the ground joint. A second ball retention device is included to allow for stem packing if desired. In this configuration, using a conical screen in between the ball retention device and basket screen is recommended. Note that this will greatly reduce the cooling capacity!

Made in the USA by a scientific glass manufacturer! This is nice thick 2.5mm wall American glass. Joint length is 22mm.

Compatible with the Z-stem ecosystem of wood sleeves and mouthpieces.
