Finding The Right Downstem.
Share
A **downstem** is a crucial component of a water pipe, bong, or bubbler. It is a long glass tube that extends from the pipe’s joint into the main chamber, helping to diffuse smoke or vapor into the water. This process cools and filters the smoke for a smoother and cleaner hit. Downstems often have slits or holes at the bottom that break up the smoke into smaller bubbles, further cooling and filtering it before inhalation.
Attached vs. Detachable Downstems
Some pipes come with a **fixed downstem**, which is permanently attached, while others feature a **removable downstem**. If your pipe doesn't come with one, you can purchase a separate downstem to insert through the joint. Downstems come in various lengths and joint sizes, so it’s important to measure your pipe correctly before purchasing a new one.
Measuring a Downstem
Downstems are measured by two key factors: **joint size** and **downstem length**.
- **Joint Size:** The joint size refers to the diameter of the pipe's connection point where the downstem is inserted. The most common joint sizes are:
- **10mm:** Small (about the size of your pinky).
- **14.5mm:** Medium (about the size of your index finger) — the most popular size.
- **18.8mm:** Large (about the size of your thumb).
You will also need to determine if your joint is male or female. For downstems, pipes with **female joints** are required since the downstem needs to be inserted into the joint.
- **Downstem Length:** Length is measured from the end of the ground joint to the bottom of the downstem, where the slits or holes diffuse the smoke. You want to ensure that the downstem reaches the water in the main chamber but does not touch the base of the pipe.
**How to Measure:** You can measure the length by inserting a pencil into the joint and marking where the joint meets the pipe. Remove the pencil and measure the length from the tip to the notch.
Types of Downstems
Different types of downstems offer various methods of filtration, impacting the smoothness and flavor of your hit. Some popular styles include:
- **Classic Slitted Downstems:** These have simple slits at the base, offering basic but reliable filtration with every hit. They are easy to clean and durable, making them a popular choice for beginners.
- **Tree Perc Downstems:** These downstems contain multiple arms, like tree branches, that offer superior filtration but require a stronger pull and frequent cleaning due to clogging.
- **Firecut Downstems:** Known for preserving flavor, these downstems offer excellent diffusion without requiring much pull, although they may clog quicker.
- **Showerhead Downstems:** Similar to internal percolators, showerhead downstems have multiple small slits or holes around the base, offering smooth filtration. They work well in combination with other percolators for a smoother hit.
- **Honeycomb Downstems:** These downstems feature a honeycomb-like pattern at the base for maximum diffusion and airflow, making them ideal for users who want enhanced filtration without sacrificing ease of use.
Popular Downstem Types
- **Slitted Diffuser:** The most common and simplest option with basic slits for consistent diffusion.
- **Tree Perc Downstem:** Provides enhanced filtration through multiple arms but requires more maintenance.
- **Showerhead Downstem:** Uses a circular design with slits to create smooth hits while complementing additional percolators.
- **Firecut Downstem:** Known for preserving flavor but can clog easily due to finer diffusion.
By choosing the right downstem for your pipe, you can significantly improve the quality of your smoking experience, ensuring better flavor, smoother hits, and optimal filtration.
