Abstract: A particularly durable two-piece packing ring for sealing fixed and reciprocating cylindrical elements such as sight glasses of steam boilers, puff iron valves and the like where gland nut assemblies are required to seal such tubes and rods, this packing ring being entirely non-metallic and in two mating parts, that is, an outer ring and an inner ring with preferably differently tapered confronting faces to be forced together by a gland nut for a limited interface sealing contact.
