This carb cap is blown for optimal use with the Puffco Peak chamber. With a fantastic colorway not found on any Puffco branded products as well as fantastic airflow, accessories like this give you a chance to individualize your experience using the Puffco products with an accessory that not everyone else has.
If you don't own a Peak this carb cap would still be perfect for any standard or flat-top banger or terp slurper as well.
