Specifications Features
Every MPI™ Fitting has the features shown below: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.Back ferrule with corrosion-resistant Parker Suparcase® provides a strong mechanical hold on the tube.Longer thread area for improved resistance to pressure and load on the ferrules.Molybdenum disulfide-coated inverted nut helps prevent galling, provides easier assembly, and permits multiple remakes.Long tube-support area improves resistance to vibration and line loads.
Specifications Materials And Identification
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.
