Report of experimental work at U S Navy Marine Engineering Laboratory, leading to design of nonlubricated seal for air compressors intended for shipboard use, which successfully operated 1500 hr at discharge pressure of 4500 psi; seal consisted of sleeve made of 25% glass-filled TFE and follower made of polyimide material; long-term operation occurred in chromium-plated cylinder bore; in later evaluations follower material was changed to metal impregnated carbon-graphite, etc.
