The function on this dry catcher, due to its size, is hands down the chuggiest dry catcher I've ever seen function. The dry catcher, the water, hell even the piece you choose to use, rumbles!
This dry catcher made by Grab Labs has an 18mm male joint and an 18mm female joint, allowing it to be used in 18mm pieces with 18mm slides. (I can include a 14mm reducer for a few extra bucks so that 14mm slides can be used as well.)
I forgot to mention that this dry catcher has a 29(?)mm joint with cap; this is to allow the user to add new water as well as remove dirty water with ease
