Parker Hannifin MPI™ connections are engineered and manufactured to be secure and gas-tight while being made manually (wrench turns) or hydraulically using a set tool. This connection has application throughout industry, including off-shore oil and gas exploration platforms, research labs, and other facilities that require operating pressures to 15,000 psi.

MPI™ Fittings are ideally suited to handle liquids, gases, or chemicals and can be used on a wide variety of tubing materials including: Instrument Grade thick-walled annealed 316 SS, 1/8th Hard (cold drawn) 316 SS MPI tubing, and 2507 Super Duplex MPI tubing. Every Parker MPI™ Fitting is supplied complete with both ferrules and compression gland nut, ready to install.

NOTE:
  • Add to the part number either -SS or -2507 depending on selected material. (Example: 16-16 FBMP7-SS)
  • Bulkhead hole approximately 1/64" (0.015") larger than R Thread major diameter.
  • Dimensions in inches are for reference only, subject to change.
    • WBMP7 MPI™ Bulkhead Union Connector
