What is Pyplok  ? 01-180-001



Fast, Reliable and Tamper Proof fittings with operating pressures over 9000 PSI (620 Bar).
A hydraulically powered compression toolswages the fitting over the pipe or tube plastically deforming the fitting. This process forms a 360° radial compression around thepipe forming a permanent leak free seal.

In 1968 McDonnell Aircraft in St. Louis, Mo first developed the technology to affect a 360° radial compression swage as areplacement for threaded AN/MS tube fittings on the F-4 fighter. Threaded joints were less reliable in applications of high stressesand loads. McDonnell Aircraft licensed a company, named at that time, Deutsch Metal Components in Gardena, California, tomanufacture the fittings for them that were used on the F-4 Fighter. As time went by, Deutsch extended the product materialrange, configurations, and pressures to become the leading supplier of Mechanically Attached Fittings (MAF’s) to the entire scope ofAerospace/Defense Industry applications in the United States, Canada, Brazil, China, and Europe.

In 1978, Deutsch Metal Components expanded the aerospace tube fitting technology to patent a NPS pipe and OD tube fittingsystem called PYPLOK
®. Originally developed for the US Navy, it expanded over the years to provide products and solutions to thePetrochemical 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. The product line eventually expanded to include fittings to join pipe and tube up to 2”NPS and66MM for a range of pipe schedules and tube wall thickness; in a variety of materials such as Stainless Steel (types 316, Duplex andSuper Duplex), Carbon Steel, Copper Nickel (CUNI), Copper and Aluminum. Testing and qualification to all industry standards overthe years has shown the PYPLOK® System to be superior to a welded system as well as being a major cost and time savings on anoverall installed basis.

In 2004, the family owners of Deutsch Metal Components decided to sell their company to private equity investors from theUnited Kingdom. The company’s named was subsequently changed to Design Metal Connections. With new ownership, and beingpredominantly an Aerospace/Defense tube fitting supplier, a decision was made to divest the PYPLOK
® Product Line and to foregothat business for which it served and concentrate on the aerospace tube fitting market.

Tube-Mac Industries Ltd., was a longtime user of PYPLOK
® and proponent/advocate of non-welded technology in their own right asdesigners, manufacturers, and installers of a 37° flared and retain ring flanged systems for pressures up to 10,000PSI (690) andpipe sizes to 10” NPS. Design Metal Connections offered to sell Tube-Mac the PYPLOK® Product line complete with all engineering,tooling, and manufacturing processes required to continue the manufacturing of PYPLOK® in the same manner as before in orderto service all markets outside of the Aeronautics Industry. In January of 2007, the sale was completed and Tube-Mac, as an ISO9001:2008 certified manufacturer, began to produce and market the PYPLOK® Product line. PYPLOK® fittings are ABS, CRN DNV andNAVSEA approved.
