Parker provides a diverse range of fittings, valves and couplings for today s aerospace and derivative markets. Our unique fittings, including Nutlock and Dynatube , are designed for the high-temperature, high-pressure, no-leak requirements of aircraft and aerospace fluid and pneumatic systems. Parker s breakaway valves are proven lifesavers that separate under crash loads when the fluid lines exceed a predetermined value. Upon separation, the valves automatically seal the fluids in the lines to effectively prevent spills. Our single shut-off, thread-lok, slide-lok and indi-lok valved couplings are compatible with all standard and many exotic fluids, offering superior performance during the operation and maintenance of fluid systems.
