Pulsar RöK Bullet Carb Cap has a rating of 5.0 stars based on 1 reviews.
Provides an excellent seal with the beveled edge of the silicone collar. The rounded bullet shape allows you to push puddles of your concentrates around on the coil surface.
Made with durable borosilicate glass and measures 21mm in diameter at the widest point. This bullet style carb cap is made for use with concentrates.
Note: This cap has an extended nipple and will not fit the standard silicone collar that comes with the original RoK design.
