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).
