Continued progress in the development of selflubricated piston and rod seals for oil-free, highpressure air compressors is described. Seal material characteristics based on filled polyetrafluoroethylene PTFE as well as new, potentially improved seal materials are discussed. Piston speeds up to 450 feet per minute were investigated. Wear results from several long-term tests at 4500 and 5000 pounds per square inch are shown. A useful piston seal life exceeding 2000 hours was demonstrated.
