Tube socket weld tees make a permanent three-way connection in instrumentation tubing, with two socket weld tube ends and one male NPT thread. They are typically used to tap a pressure gauge, transmitter, switch or vent into a welded tube run, so the instrument can be removed at the threaded port while the tubing stays welded.
The difference between the two types is where the thread sits. On a male run tee, the NPT thread is on one end of the straight-through run, and the tube enters through the opposite run end and the side branch. On a male branch tee, the NPT thread forms the side branch, with tube on both ends of the run. A branch tee suits a straight tube run with an instrument off the side, while a run tee suits a port-mounted tee where the tube leaves at right angles.
Both types are SS316 and cover tube sizes from 1/8" to 2" and 6 mm to 38 mm. Common sectors include oil and gas, petrochemical and power generation, where welded tubing is specified for vibration resistance or code compliance.
