SUITABILITY OF VITON B O-RINGS FOR USE IN 3000 PSI HYDRAULIC SYSTEMS CONTAINING PETROLEUM BASE OR PHOSPHATE ESTER FLUIDS
Abstract
Results of dynamic performance tests of Viton B O-rings indicate that Viton B O-rings of 70 Shore A hardness with Teflon backup rings will perform satisfactorily at 180 F in 3000 psi hydraulic systems containing phosphate ester fluids. In addition, the results indicate that the O-rings will perform equally as well under these conditions in hydraulic systems containing petroleum base fluids. As reported previously, the Teflon backup rings do not stand up at 300 F under the test conditions. Backup rings made of a 90 Shore A Viton B stock showed even greater wear. (Author)
