Learn what a spinner cap does, how it works with terp pearls, and step-by-step tips for getting smoother, more flavorful dabs.
Quick Answer
A spinner cap is a carb cap designed to direct airflow so terp pearls spin inside your banger, spreading heat and improving vaporization. Use it with a proper banger and pearls, and adjust the cap's airflow to get the most flavor and efficiency.
Why Use a Spinner Cap?
A spinner cap isn't just a fancy carb cap. Its angled airflow creates a vortex that spins terp pearls across the banger surface. This helps distribute the oil evenly and prevents hot spots, so you get more consistent vapor and better flavor.
Compared to a flat or bubble cap, a spinner cap offers more control over airflow direction. You can fine-tune the spin speed by rotating the cap, which is a big advantage when you're using different banger shapes or pearl sizes.
Choosing the Right Spinner Cap and Pearls
Not all spinner caps fit every banger. Check the joint size (usually 10mm, 14mm, or 19mm) and the cap's design. A cap that's too loose won't create enough pressure to spin pearls, while one that's too tight can restrict airflow too much.
Terp pearls come in different sizes, typically 4mm to 8mm. Smaller pearls spin faster and are great for small bangers, while larger pearls hold more heat and work well for bigger dabs. Start with one pearl and add more if you need more spin.
The Blob Full Color Spinner Cap is a solid choice because it's made in Nevada and designed for dialed-in function. It comes in a variety of colors, including UV-reactive and satin finishes, so you can match it to your setup.
How to Use a Spinner Cap: Step-by-Step
- Set Up Your Banger and Pearls: Place one or two terp pearls into your banger before heating. Make sure the pearls are clean and dry. Choose a banger that fits your spinner cap snugly. Check that the pearls move freely and the cap fits well before heating.
- Heat Your Banger and Let It Cool: Heat the banger evenly with a torch until it reaches your desired temperature. For low-temp dabs, heat for about 30 seconds and then let it cool for 30-45 seconds. If you have a temperature gun, aim for 450-550°F. Don't overheat—too hot can burn your oil and ruin the flavor.
- Apply Your Concentrate: Drop your concentrate into the banger using a dab tool. Start with a small amount to avoid overflow. Let it melt slightly. Use a rice-sized dab to start; you can add more later if needed.
- Place the Spinner Cap and Spin: Place the spinner cap on the banger and gently adjust it to direct the airflow. You should see the pearls start spinning. Rotate the cap to control the spin speed and direction. If the pearls aren't spinning, adjust the cap's position or check the airflow holes.
- Inhale Slowly and Steadily: Inhale slowly and steadily through the rig. The spinning pearls will keep the oil moving and vaporizing. Continue until the vapor thins out. Stop when you see no more vapor—don't keep heating the banger.
- Clean and Maintain: After each dab, wipe the banger with a cotton swab to remove residue. Clean the spinner cap and pearls with isopropyl alcohol regularly to keep them functioning well. Regular cleaning prevents buildup and keeps your cap and pearls spinning smoothly.
