Made of delrin with a 1/2" bore drip tip built in, these are the ultimate top caps for cloud chasers. These fit the TOBH, Stillare, Vulcan, Crest cap, HALO cap so far. These are available in two styles and two colors - dome cap like the Stillare or finned cap like the TOBH and white or black delrin.
Does not fit on most EHPro TOBH. EHPro rep confirmed they changed the wall/sleeve size.
