Down Stems

A downstem is a crucial part of a bong that connects the bowl to the water chamber, allowing smoke to pass through for filtration. It helps cool and smooth out each hit, making for a more enjoyable smoking experience. Without a downstem, the smoke would be harsher and less filtered.

The size of your bong stem depends on the length and joint size of your bong. Measure the length from the bottom of the joint to the inside base of your bong to ensure a proper fit. At Bong Warehouse, we offer a variety of stem sizes to match different bongs.

Metal downstems are durable, shatterproof, and often come with rubber grommets for a tight seal. Glass downstems, on the other hand, provide better filtration with diffuser slits for a cleaner, smoother hit. The best choice depends on your preference for durability versus filtration.

A glass bong stem is a downstem made from borosilicate glass, designed to withstand heat and provide better filtration. Many glass downstems feature slits that break up the smoke into smaller bubbles, increasing surface area for enhanced cooling and smoother hits.

A metal bong stem and bowl can fit most bongs, but you need to ensure the joint size and length match your bong’s setup. Metal stems are commonly used with rubber grommet bongs and are a great option for those who want a durable, long-lasting alternative.

A metal downstem is made from anodized aluminum or stainless steel, making it more resistant to breakage. Unlike glass downstems, metal ones don’t have diffuser slits, so they provide less filtration but are ideal for those prioritizing durability and longevity.

Cleaning your bong stem regularly prevents resin buildup and ensures optimal airflow. Soak it in isopropyl alcohol and salt, shake thoroughly, and rinse with warm water. For metal stems, you can also use boiling water or pipe cleaners for deep cleaning.

Yes, metal bong stems are safe to use as long as they are made from high-quality, non-toxic materials like anodized aluminum. These materials are heat-resistant and won’t release harmful chemicals when heated, making them a reliable choice for frequent use.
