Made by Waterway and the plumbing is a 3/4" Slip connection for water and 3/8" Barb for air or ozone tubing. We also include a short length of adapter tubing, because most ozonators today use 1/4" I.D. ozone line.
Can be used as an ozone jet or often used as cluster jets (many jets installed in one seat).
Requires front internal (wall fitting 215-9860) sold seperately.
