Expand your options with the Pulsar ROK Silicone Cloud Collar Upgrade - XL. 

The XL Cloud Collar is made with food-grade silicone and provides a perfect fit with your Pulsar Rok Electric Dab Rig. It's made just like the original collar you got with your rig but is taller than the original.

The extended size creates more space between the coil and the carb cap. Combined with the beveled top, that allows a perfect seal with almost any carb cap so you can experiment with more options. 

Though the sleeve works with most carb caps, it'll provide the best function and seal with bullet and bubble styles. Sold in a set of 5.
