Diffused 6.5cm Coloured Glass Downstem 19/14mm | Billy Mate

Compact, colourful and built for smooth water diffusion, the Billy Mate Diffused 6.5cm Coloured Glass Downstem 19/14mm is a premium replacement downstem for compatible bongs requiring a shorter stem length.

Made from premium borosilicate glass, each downstem features diffuser slits at the bottom, a 19mm outer joint and compatibility with standard 14mm cone pieces.

Available in Charcoal, Green, Navy Blue and Pink.

The bottom of the Diffused 6.5cm Coloured Glass Downstem 19/14mm features multiple diffuser slits.

Instead of directing all airflow through one large opening, the slits divide the airflow into smaller streams as it passes through the water.

Benefits include:

• Multiple diffuser slits
• Increased bubble production
• Better water diffusion
• More even airflow through the water
• Smooth draw
• Compact design
• Premium borosilicate glass

This is one of the shorter Billy Mate downstem options, measuring approximately 6.5cm from the bottom of the joint to the bottom of the stem.

Its compact size makes it suitable for compatible bongs that require a shorter downstem.

Always measure your existing downstem before ordering.

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

Choosing the correct downstem length is important.

Remove your current downstem and measure from the bottom of the frosted joint to the very bottom of the stem.

For this model:

Approx. 6.5cm from the bottom of the joint

Approx. 10cm overall length

Do not use the overall length alone when matching your replacement downstem. The 6.5cm measurement from the bottom of the joint is the important measurement for checking how far the stem will extend into your bong.

Always check both the joint size and stem length before ordering.

Billy Mate offers both diffused and no-slit downstem designs.

A diffused downstem has multiple slits around the lower section. These divide the airflow into smaller streams and create additional bubbles through the water.

A no-slit downstem has a fully open bottom. This design is generally easier to rinse straight through because there are no small diffuser openings where residue can collect.

Choose the diffused version if your priority is:

• Increased water diffusion
• More bubbles
• More even airflow through the water

Choose the no-slit version if your priority is:

• Easier cleaning
• Straight-through airflow
• Fewer places for residue to get trapped

This compact Billy Mate downstem gives you practical diffusion without needing a long stem.

You get:

• 6.5cm downstem length
• 10cm overall length
• 19/14mm joint configuration
• Fits standard 14mm cone pieces
• Diffuser slits for improved water diffusion
• Premium borosilicate glass
• Four premium colour options
• Billy Mate branding

If your bong requires a shorter downstem, the Diffused 6.5cm Coloured Glass Downstem 19/14mm gives you the right compact size with the added benefit of water diffusion.
