High Temperature Hydraulic Seals
Abstract
This program investigated and evaluated high-temperature hydraulic sealing technology, including seals, fluids and actuator materials. Test limits for fluid pressure and temperature were 8000 psi and 700 deg F respectively. The original plan to investigate CTFE fluid at 350 deg F as well as other fluids at higher temperatures was reduced in scope to include only the higher temperature investigation. Seals were obtained from 11 manufacturers. Design requirements including materials, dimensions, clearances and tolerances were established and test modules were constructed from the detail designs which were produced. Nine piston seals and one rod seal were tested at temperatures ranging from -65 to +600 deg F and pressures to 6000 psi. Fluid performance under these conditions was evaluated. Details of this activity and results of the effort are summarized in this report.
