13.5cm Glass Diffused Stem 19/14mm | Billy Mate

Upgrade your setup with the Diffused 13.5cm Glow Glass Stem 19/14mm by Billy Mate, featuring 6 diffuser slits, premium coloured glass and a Billy Mate logo that glows in the dark.

Designed for compatible bongs using a 19mm stem joint and 14mm cone piece, this longer glass stem combines effective water diffusion with premium Billy Mate styling.

Available in Charcoal, Pink, Blue and Green, and you choose your colour.

The Diffused 13.5cm Glow Glass Stem 19/14mm features 6 diffuser slits around the bottom section.

These slits help spread airflow through the water instead of releasing it through one large opening.

Benefits include:

• 6 diffuser slits
• Increased bubble production
• Better water diffusion
• More even airflow
• Smooth draw
• Premium glass construction

If you prefer a diffused stem over a fully open no-slit design, this is a great option.

The Billy Mate logo is designed to glow in the dark after exposure to light.

Place the stem under a bright light to charge the glow, then watch the Billy Mate branding illuminate when the lights go down.

The coloured glass gives the stem a premium look during the day, while the glowing logo adds extra character at night.

This stem uses the common 19/14mm joint configuration:

• 19mm outer joint
• Fits a standard 14mm cone piece
• Suitable for compatible glass bongs using a 19/14mm stem setup

The Diffused 13.5cm Glow Glass Stem 19/14mm is available in four colours:

Billy Mate offers both diffused and no-slit glass stem options.

The Diffused 13.5cm Glow Glass Stem 19/14mm uses 6 diffuser slits to spread airflow through several openings, creating more bubbles through the water.

A no-slit stem uses a fully open bottom, which can be easier to rinse and clean because there are no small diffuser openings.

Choose the diffused version if your priority is increased water diffusion.

Choose the no-slit version if your priority is easier cleaning and a simple straight-through design.

This stem combines practical diffusion with premium Billy Mate styling.
