BA3100 Series

View Larger

The BA3100 Series self flare tee shaped adapter is made up of two opposing tube connections and a female pipe thread tee connection. For the tube connections, the OD and wall thickness of the tubes to be joined to the Self Flare fitting will determine the dash size(s) and whether a BA or BAX version of the Self Flare fitting is required for the application.

Standard Features:

  • Tube sizes from -2 (.125 inch) to -32 (2.00 inch)
  • Female pipe thread sizes from 1/8 inch NPTF to 2 inch NPTF
  • Machined from solid steel bar stock - free from brazing, welding and soldering
  • BAX3100 adapters available for applications with heavy wall tubing
  • Includes swivel tube nuts and Self Flare sleeves

Standard Materials:

  • Steel construction
  • Black oxide finish on fitting body and tube sleeves
  • Zinc plated, steel swivel tube nuts


  • System operating conditions and maximum pressures dictate tubing requirements. LDI Self Flare fittings require matching the tube connection on the adapter to the tube wall thickness selected for the application.
  • Fully annealed and cleaned tubing is preferred. Consult factory for applications that require alloy tubing or tube wall thicknesses that exceed published limits for BA and BAX tube connections.

When hydraulic systems require the use of large diameter tubing, have connections in confined spaces or require a large number of tube connections, the ends of the tube assemblies can be flared prior to system assembly using a Vise Held Preset Tool or Hydraulic Preset Tool.
