Downstems

At Bong Empire, we stock one of Australia’s best ranges of downstems for bongs, designed to deliver smoother, cleaner, and more flavourful hits. A downstem is a crucial part of any bong, connecting your bowl or cone piece to the water chamber and ensuring smoke is filtered through water before inhalation. Whether you need a replacement downstem, want to upgrade to a diffuser downstem, or prefer a durable metal bong stem, you’ll find the perfect fit here.

Our collection includes borosilicate glass downstems for pure flavour, metal downstems for long-lasting durability, and a variety of sizes and colours to match your bong setup. From standard pieces to slitted diffuser stems that create maximum bubbling action, we’ve got options to suit every style and budget.

Why Downstems Matter

A quality downstem doesn’t just connect your bowl to your bong – it transforms your entire smoking experience. By breaking smoke into smaller bubbles as it passes through water, the downstem cools and filters the hit, reducing harshness and irritation. This makes every pull smoother, cleaner, and more enjoyable.

At Bong Empire, we only stock high-grade, heat-resistant downstems that are built for performance. Whether you prefer classic straight stems or diffuser styles with extra percolation, you’ll notice the difference from the first hit.

Find the Right Downstem for Your Bong

Not sure which downstem you need? Here’s how to get it right:

  • Joint Size – The most common sizes are 10mm, 14mm, and 18mm. Your downstem’s joint size must match your bong’s joint.
  • Length – Measure from the bottom of the ground joint (where the cone sits) to the end that rests in the water. Common lengths include 8cm, 11cm, 14cm, and 17cm.
  • Material – Choose glass downstems for clean flavour and diffusion, or metal downstems if you want something unbreakable.
  • Diffusion – Upgrade to a diffuser downstem with slits or holes at the base for extra bubbling, cooling, and smoother hits.

Our range makes it easy to match your bong perfectly, whether you’re replacing a broken stem or looking for an upgrade.

Customise & Upgrade Your Bong Setup

Looking to enhance your session? Swap your standard downstem for a diffuser version for better cooling and smoother rips. Prefer a pop of colour? Choose from clear, frosted, or coloured downstems that add personality to your bong. Want something travel-friendly? Pick an unbreakable metal downstem that can handle everyday use.

FAQs about Downstems

What is a downstem for a bong?

A downstem is a tube that connects the cone piece to the water chamber of your bong. It allows smoke to pass through water for cooling and filtration before being inhaled.

What is a diffuser downstem?

A diffuser downstem has multiple slits or holes at the base. These break smoke into smaller bubbles, increasing surface area contact with the water, which leads to smoother, cooler, and cleaner hits.

Are glass or metal downstems better?

Glass downstems provide superior flavour and smoother diffusion, while metal downstems are nearly indestructible and ideal for travel or everyday use. The best choice depends on whether you prioritise taste or durability.

How do I measure the right downstem size?

Measure your bong’s joint size (10mm, 14mm, or 18mm) and the length from the joint to the bottom of the water chamber. This ensures a perfect fit and proper airflow.

Can I replace a broken downstem?

Yes – most bongs use removable downstems, which are easy to replace. At Bong Empire, we stock a full range of replacement glass and metal downstems in multiple sizes.

How do I clean a downstem?

Soak your glass downstem in isopropyl alcohol and salt, then rinse with warm water. For metal stems, you can also boil them or use a pipe cleaner for deeper cleaning.
