The Puffco Peak Pro Ball Cap & tether by Puffco is a no-brainer upgrade on the stock oculus cap, it gives the user the function of a directional airflow cap providing full 360-degree control and allowing for even heating and thick vapour production. The resulting vapour hit is smoother and more consistent with even more vapour so you can direct the air into every single remaining drop of oil so you don’t waste a penny. The Black Peak Pro Ball Cap rubber seal will also allow you to add after-market ball caps to your set-up made by after-market heady glass blowers. Put, simply the Peak Pro Ball cap is a guaranteed imrpovement on the stock cap for everyone that prefers the experience of a directional airflow carb cap over the Oculus cap pear spinner design. The Puffco Peak Pro Ball Cap gives you the consumption experience of a more heady directional airflow carb cap. Only compatible with the Puffco Peak Pro.
