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:
Ferrules are sold in Sets and are shipped in Gang of 8 on a plastic holder.

Features

 N/A Every MPI™ Fitting has the features shown below:
  1. Front ferrule with corrosion-resistant Parker Suparcase forms a seal between the tube, body and ferrule. It also provides a mechanical hold on the tube.
  2. Back ferrule with corrosion-resistant Parker Suparcase® provides a strong mechanical hold on the tube.
  3. Longer thread area for improved resistance to pressure and load on the ferrules.
  4. Molybdenum disulfide-coated inverted nut helps prevent galling, provides easier assembly, and permits multiple remakes.
  5. Long tube-support area improves resistance to vibration and line loads.

Materials and Identification

 N/A Standard MPI™ Fittings and Valves are made of Heat Code Traceable 316 SS or optional 2507 Super Duplex materials. Tubing and fitting materials should be selected based on compatibility with the fluid or gas media. Part numbers for MPI™ Fittings use symbols that identify their style, size, and composition. 2507 material is easily identified by a groove in the gland nut hex.

MPI™ Fittings Pressure Ratings

 N/A The maximum pressure rating is marked on each fitting. MPI™ working pressures to be determined by selected tubing. Please see tables on pages 10 and 11 for specific working pressures.
  • Size 4 (1/4") MPI™ - to 15,000 psi
  • Size 6 (3.8") MPI™ - to 15,000 psi
  • Size 8 (1/2") MPI™ - to 15,000 psi
  • Size 9 (9/16") MPI™ - to 15,000 psi
  • Size 12 (3/4") MPI™ - to 15,000 psi
  • Size 16 (1") MPI™ - to 12,500 psi using 316 SS MPI tubing, 15,000 psi using MPI 2507 Super Duplex tubing with -XF Ferrule Option
Note: Tube and pipe thread sizes are designated by the number of sixteenths of an inch (1/4” tube = 4/16” or 4). See "How to Order" on page 8 for additional information.
