The LSBSO400 has a very large barb to allow for a higher flow of water and a valve to allow for an individual line to be shut off. The barb is too big to fit into 1/2" tubing and can only be used with 3/4" or larger tubing.
Use the .400 Barb Punch () to make the appropriate size hole for this fitting.
This fitting allows a flow of 160 GPH at 10 PSI.
