Specialty 3/8" to 1/4" reducing Tee. It has great uses when designing larger systems with a 3/8" backbone. Two ports fit 3/8" tubing and middle port fits 1/4" tubing.
I just setup the Ultimate system to 3 of my enclosures and, wow! Was i surprised!
the pump does a great job at distributing water, the nozzles work great " fine mist", zip drip does exactly what its supposed to. The seconds timer is user friendly, the mistking goes off a few times a day. total setup time was about 25 minutes. So far In my opinion it beats anything out on the market! I definitely recommend it!
