In 1978, Deutsch Metal Components expanded the aerospace tube fitting technology to patent a NPS pipe and OD tube fitting system called PYPLOK®.

Originally developed for the US Navy, it expanded over the years to provide products and solutions to the Petrochemical market as well as other industrial process plants. As an equal to or better than replacement for welding or brazing, it found acceptance in many areas.

A hydraulically powered compression tool swages the fitting over the pipe or tube plastically deforming the fitting. This process forms a 360° radial compression around the pipe forming a permanent leak free seal. The technology to provide this seal is unique only to PYPLOK® Machanically Attached Fittings.
