Proxy Ball Cap and Teather by Puffco The Puffco Proxy Ball Cap is a no-brainer upgrade over the Proxy’s stock oculus carb cap. The 360 directional air flow gives you control of the airflow as it hits your dab, allowing for even heating and thick clouds of vapour production. The resulting hit is more consistent and vapour packed as you can direct the air into every single remaining drop of oil so you don’t waste a single penny. The Ball Cap comes with a secure rubber seal that will allow you to add more heady after-market ball caps to your set-up made by a range of after-market heady glass blowers.
