Developed initially for the demanding performance requirements of NASA, Parker Stratoflex invented the original “beam seal” Dynatube® design for high temperature, high pressure aerospace systems. Parker Stratoflex’s Dynatube fittings have been proven through decades of testing, development, and installation in nearly every aerospace application.
Using an elegantly simple geometric design and the utilization of compression and load forces, Dynabute fittings create several redundant seals for a zero-leak seal – even after repeated assembly and disassembly. Dynatube fittings can also be used on aircraft hydraulic systems without the need for safety wiring, as proven by repeated NASA testing in high vibration rocket applications.
