SEALS FOR 5200 PSI AIR SYSTEMS

Abstract

The objectives of this investigation were (1) to develop elastomeric seals for 5200 psi air systems wherein the compressors are lubricated with either petroleum-base fluids or with phosphate-ester fluids, and (2) to prepare a specification for these seals. A Viton B stock (377-112) was previously developed and shown by performance tests to be very suitable for this purpose. However, O-rings of this stock corroded steel and bronze under humid conditions. This problem was solved by washing the O-rings with soap and water prior to placing them in contact with the metals. Dynamic and static performance tests of 377-112 O-rings lubricated with dry MoS2 verified the suitability of this stock and showed that this lubricant was as satisfactory as MIL-L-4343A grease currently used in high pressure air systems. A specification was prepared based on tests conducted on specimens of stock 377-112.
