摘要： A torque operable conduit union and mating spanner wrench are shown for the hammerless coupling of the ends of abutting fluid conduits, such as pipe, hoses, and fittings. A union nut body has an upper peripheral planar face, a lower peripheral planar face and a circumferential side wall. The circumferential side wall has a series of protuberances extending outwardly therefrom which define at least two circumferentially spaced wrench receiving formations. Each of the wrench receiving formations includes a slot portion which communicates with a transverse opening portion of the formation. The mating spanner wrench has a bridge region which spans certain of the receiving formations and engaging tangs which engage the slot portions of the formations for applying torque to the union nut.
