The TFC G1/4 Thread - 1/2" ID Barb Connector fits standard G1/4" ports and secures tubing with its flanged barb. The barb fitting can be used in conjunction with one of our reusable clamps. The fittings have a knurled ring at the base for tool-less usage. The shortened barb length makes using these in tight places much easier. A rubber o-ring is provided to keep a tight seal.
