Parker Hannifin, original Patent Holder (US 6851729 B2), for "Tube Fitting, Medium Pressure" developed the MPI Medium Pressure compression fitting connections to be secure and gas-tight while being made manually (wrench turns) or hydraulic 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 (1035 bar).

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 or 317 SS MPI tubing, and 2507 Super Duplex MPI tubing up to 1" OD. 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)
  • Dimensions in inches are for reference only, subject to change.
  • Pressure Rating of Fittings is controlled by tubing selected and choice of ASME Standard.
  • -XF Ferrules are required for 3/4" and 1" 316 SS or 2507 Super Duplex Tubing.
